RSYSLOG.CONF(5)        Linux System Administration       RSYSLOG.CONF(5)

NAME         top

       rsyslog.conf - rsyslogd(8) configuration file

DESCRIPTION         top

       The rsyslog.conf file is the main configuration file for the
       rsyslogd(8) which logs system messages on *nix systems.  This
       file specifies rules for logging.  For special features see the
       rsyslogd(8) manpage. Rsyslog.conf is backward-compatible with
       sysklogd's syslog.conf file. So if you migrate from sysklogd you
       can rename it and it should work.

       Note that this version of rsyslog ships with extensive
       documentation in HTML format.  This is provided in the ./doc
       subdirectory and probably in a separate package if you installed
       rsyslog via a packaging system.  To use rsyslog's advanced
       features, you need to look at the HTML documentation, because the
       man pages only cover basic aspects of operation.

MODULES         top

       Rsyslog has a modular design. Consequently, there is a growing
       number of modules. See the HTML documentation for their full
       description.

       omsnmp SNMP trap output module

       omgssapi
              Output module for GSS-enabled syslog

       ommysql
              Output module for MySQL

       omrelp Output module for the reliable RELP protocol (prevents
              message loss).  For details, see below at imrelp and the
              HTML documentation.  It can be used like this:

              *.*  :omrelp:server:port

              *.*  :omrelp:192.168.0.1:2514 # actual sample

       ompgsql
              Output module for PostgreSQL

       omlibdbi
              Generic database output module (Firebird/Interbase, MS
              SQL, Sybase, SQLite, Ingres, Oracle, mSQL)

       imfile Input module for text files

       imudp  Input plugin for UDP syslog. Replaces the deprecated -r
              option. Can be used like this:

              $ModLoad imudp

              $UDPServerRun 514

       imtcp  Input plugin for plain TCP syslog. Replaces the deprecated
              -t option. Can be used like this:

              $ModLoad imtcp

              $InputTCPServerRun 514

       imrelp Input plugin for the RELP protocol. RELP can be used
              instead of UDP or plain TCP syslog to provide reliable
              delivery of syslog messages. Please note that plain TCP
              syslog does NOT provide truly reliable delivery, with it
              messages may be lost when there is a connection problem or
              the server shuts down.  RELP prevents message loss in
              those cases.  It can be used like this:

              $ModLoad imrelp

              $InputRELPServerRun 2514

       imgssapi
              Input plugin for plain TCP and GSS-enable syslog

       immark Support for mark messages

       imklog Kernel logging. To include kernel log messages, you need
              to do

              $ModLoad imklog

              Please note that the klogd daemon is no longer necessary
              and consequently no longer provided by the rsyslog
              package.

       imuxsock
              Unix sockets, including the system log socket. You need to
              specify

              $ModLoad imuxsock

              in order to receive log messages from local system
              processes. This config directive should only left out if
              you know exactly what you are doing.

BASIC STRUCTURE         top

       Lines starting with a hash mark ('#') and empty lines are
       ignored.  Rsyslog.conf should contain following sections (sorted
       by recommended order in file):

       Global directives
              Global directives set some global properties of whole
              rsyslog daemon, for example size of main message queue
              ($MainMessageQueueSize), loading external modules
              ($ModLoad) and so on.  All global directives need to be
              specified on a line by their own and must start with a
              dollar-sign. The complete list of global directives can be
              found in HTML documentation in doc directory or online on
              web pages.

       Templates
              Templates allow you to specify format of the logged
              message. They are also used for dynamic file name
              generation. They have to be defined before they are used
              in rules. For more info about templates see TEMPLATES
              section of this manpage.

       Output channels
              Output channels provide an umbrella for any type of output
              that the user might want.  They have to be defined before
              they are used in rules. For more info about output
              channels see OUTPUT CHANNELS section of this manpage.

       Rules (selector + action)
              Every rule line consists of two fields, a selector field
              and an action field. These two fields are separated by one
              or more spaces or tabs. The selector field specifies a
              pattern of facilities and priorities belonging to the
              specified action.

SELECTORS         top

       The selector field itself again consists of two parts, a facility
       and a priority, separated by a period ('.'). Both parts are case
       insensitive and can also be specified as decimal numbers, but
       don't do that, you have been warned.  Both facilities and
       priorities are described in syslog(3). The names mentioned below
       correspond to the similar LOG_-values in /usr/include/syslog.h.

       The facility is one of the following keywords: auth, authpriv,
       cron, daemon, kern, lpr, mail, mark, news, security (same as
       auth), syslog, user, uucp and local0 through local7. The keyword
       security should not be used anymore and mark is only for internal
       use and therefore should not be used in applications.  Anyway,
       you may want to specify and redirect these messages here. The
       facility specifies the subsystem that produced the message, i.e.
       all mail programs log with the mail facility (LOG_MAIL) if they
       log using syslog.

       The priority is one of the following keywords, in ascending
       order: debug, info, notice, warning, warn (same as warning), err,
       error (same as err), crit, alert, emerg, panic (same as emerg).
       The keywords error, warn and panic are deprecated and should not
       be used anymore. The priority defines the severity of the
       message.

       The behavior of the original BSD syslogd is that all messages of
       the specified priority and higher are logged according to the
       given action. Rsyslogd behaves the same, but has some extensions.

       In addition to the above mentioned names the rsyslogd(8)
       understands the following extensions: An asterisk ('*') stands
       for all facilities or all priorities, depending on where it is
       used (before or after the period). The keyword none stands for no
       priority of the given facility.

       You can specify multiple facilities with the same priority
       pattern in one statement using the comma (',') operator. You may
       specify as much facilities as you want. Remember that only the
       facility part from such a statement is taken, a priority part
       would be skipped.

       Multiple selectors may be specified for a single action using the
       semicolon (';') separator. Remember that each selector in the
       selector field is capable to overwrite the preceding ones. Using
       this behavior you can exclude some priorities from the pattern.

       Rsyslogd has a syntax extension to the original BSD source, that
       makes its use more intuitively. You may precede every priority
       with an equals sign ('=') to specify only this single priority
       and not any of the above. You may also (both is valid, too)
       precede the priority with an exclamation mark ('!') to ignore all
       that priorities, either exact this one or this and any higher
       priority. If you use both extensions then the exclamation mark
       must occur before the equals sign, just use it intuitively.

ACTIONS         top

       The action field of a rule describes what to do with the message.
       In general, message content is written to a kind of "logfile".
       But also other actions might be done, like writing to a database
       table or forwarding to another host.

   Regular file
       Typically messages are logged to real files. The file has to be
       specified with full pathname, beginning with a slash ('/').

       Example:
              *.*
              /var/log/traditionalfile.log;RSYSLOG_TraditionalFileFormat
              # log to a file in the traditional format

       Note: if you would like to use high-precision timestamps in your
       log files, just remove the ";RSYSLOG_TraditionalFormat". That
       will select the default template, which, if not changed, uses RFC
       3339 timestamps.

       Example:
              *.*     /var/log/file.log # log to a file with RFC3339
              timestamps

       By default, files are not synced after each write. To enable
       syncing of log files globally, use either the
       "$ActionFileEnableSync" directive or the "sync" parameter to
       omfile. Enabling this option degrades performance and it is
       advised not to enable syncing unless you know what you are doing.
       To selectively disable syncing for certain files, you may prefix
       the file path with a minus sign ("-").

   Named pipes
       This version of rsyslogd(8) has support for logging output to
       named pipes (fifos). A fifo or named pipe can be used as a
       destination for log messages by prepending a pipe symbol ('|') to
       the name of the file. This is handy for debugging. Note that the
       fifo must be created with the mkfifo(1) command before
       rsyslogd(8) is started.

   Terminal and console
       If the file you specified is a tty, special tty-handling is done,
       same with /dev/console.

   Remote machine
       There are three ways to forward message: the traditional UDP
       transport, which is extremely lossy but standard, the plain TCP
       based transport which loses messages only during certain
       situations but is widely available and the RELP transport which
       does not lose messages but is currently available only as part of
       rsyslogd 3.15.0 and above.

       To forward messages to another host via UDP, prepend the hostname
       with the at sign ("@").  To forward it via plain tcp, prepend two
       at signs ("@@"). To forward via RELP, prepend the string
       ":omrelp:" in front of the hostname.

       Example:
              *.* @192.168.0.1

       In the example above, messages are forwarded via UDP to the
       machine 192.168.0.1, the destination port defaults to 514. Due to
       the nature of UDP, you will probably lose some messages in
       transit.  If you expect high traffic volume, you can expect to
       lose a quite noticeable number of messages (the higher the
       traffic, the more likely and severe is message loss).

       Sockets for forwarded messages can be bound to a specific device
       using the "device" option for the omfwd module.

       Example:
              action(type="omfwd" Target="192.168.0.1" Device="eth0"
              Port=514 Protocol="udp")

       In the example above, messages are forwarded via UDP to the
       machine 192.168.0.1 at port 514 over the device eth0. TCP can be
       used by setting Protocol to "tcp" in the above example.

       For Linux with VRF support, the device option is used to specify
       the VRF to send messages.

       If you would like to prevent message loss, use RELP:
              *.* :omrelp:192.168.0.1:2514

       Note that a port number was given as there is no standard port
       for relp.

       Keep in mind that you need to load the correct input and output
       plugins (see "Modules" above).

       Please note that rsyslogd offers a variety of options in
       regarding to remote forwarding. For full details, please see the
       HTML documentation.

   List of users
       Usually critical messages are also directed to ``root'' on that
       machine. You can specify a list of users that shall get the
       message by simply writing ":omusrmsg:" followed by the login
       name. You may specify more than one user by separating them with
       commas (','). If they're logged in they get the message (for
       example: ":omusrmsg:root,user1,user2").

   Everyone logged on
       Emergency messages often go to all users currently online to
       notify them that something strange is happening with the system.
       To specify this wall(1)-feature use an ":omusrmsg:*".

   Database table
       This allows logging of the message to a database table.  By
       default, a MonitorWare-compatible schema is required for this to
       work. You can create that schema with the createDB.SQL file that
       came with the rsyslog package. You can also use any other schema
       of your liking - you just need to define a proper template and
       assign this template to the action.

       See the HTML documentation for further details on database
       logging.

   Discard
       If the discard action is carried out, the received message is
       immediately discarded. Discard can be highly effective if you
       want to filter out some annoying messages that otherwise would
       fill your log files. To do that, place the discard actions early
       in your log files.  This often plays well with property-based
       filters, giving you great freedom in specifying what you do not
       want.

       Discard is just the single 'stop' command with no further
       parameters.

       Example:
              *.*   stop      # discards everything.

   Output channel
       Binds an output channel definition (see there for details) to
       this action. Output channel actions must start with a $-sign,
       e.g. if you would like to bind your output channel definition
       "mychannel" to the action, use "$mychannel". Output channels
       support template definitions like all all other actions.

   Shell execute
       This executes a program in a subshell. The program is passed the
       template-generated message as the only command line parameter.
       Rsyslog waits until the program terminates and only then
       continues to run.

       Example:
              ^program-to-execute;template

       The program-to-execute can be any valid executable. It receives
       the template string as a single parameter (argv[1]).

FILTER CONDITIONS         top

       Rsyslog offers three different types "filter conditions":
          * "traditional" severity and facility based selectors
          * property-based filters
          * expression-based filters

   Selectors
       Selectors are the traditional way of filtering syslog messages.
       They have been kept in rsyslog with their original syntax,
       because it is well-known, highly effective and also needed for
       compatibility with stock syslogd configuration files. If you just
       need to filter based on priority and facility, you should do this
       with selector lines. They are not second-class citizens in
       rsyslog and offer the best performance for this job.

   Property-Based Filters
       Property-based filters are unique to rsyslogd. They allow to
       filter on any property, like HOSTNAME, syslogtag and msg.

       A property-based filter must start with a colon in column 0. This
       tells rsyslogd that it is the new filter type. The colon must be
       followed by the property name, a comma, the name of the compare
       operation to carry out, another comma and then the value to
       compare against. This value must be quoted.  There can be spaces
       and tabs between the commas. Property names and compare
       operations are case-sensitive, so "msg" works, while "MSG" is an
       invalid property name. In brief, the syntax is as follows:

              :property, [!]compare-operation, "value"

       The following compare-operations are currently supported:

              contains
                     Checks if the string provided in value is contained
                     in the property

              isequal
                     Compares the "value" string provided and the
                     property contents. These two values must be exactly
                     equal to match.

              startswith
                     Checks if the value is found exactly at the
                     beginning of the property value

              regex
                     Compares the property against the provided regular
                     expression.

   Expression-Based Filters
       See the HTML documentation for this feature.

TEMPLATES         top

       Every output in rsyslog uses templates - this holds true for
       files, user messages and so on. Templates compatible with the
       stock syslogd formats are hardcoded into rsyslogd. If no template
       is specified, we use one of these hardcoded templates. Search for
       "template_" in syslogd.c and you will find the hardcoded ones.

       A template consists of a template directive, a name, the actual
       template text and optional options. A sample is:

              $template MyTemplateName,"\7Text %property% some more
              text\n",<options>

       The "$template" is the template directive. It tells rsyslog that
       this line contains a template. The backslash is an escape
       character. For example, \7 rings the bell (this is an ASCII
       value), \n is a new line. The set in rsyslog is a bit restricted
       currently.

       All text in the template is used literally, except for things
       within percent signs. These are properties and allow you access
       to the contents of the syslog message. Properties are accessed
       via the property replacer and it can for example pick a substring
       or do date-specific formatting. More on this is the PROPERTY
       REPLACER section of this manpage.

       To escape:
          % = \%
          \ = \\ --> '\' is used to escape (as in C)
       $template TraditionalFormat,"%timegenerated% %HOSTNAME%
       %syslogtag%%msg%\n"

       Properties can be accessed by the property replacer (see there
       for details).

       Please note that templates can also by used to generate selector
       lines with dynamic file names.  For example, if you would like to
       split syslog messages from different hosts to different files
       (one per host), you can define the following template:

              $template DynFile,"/var/log/system-%HOSTNAME%.log"

       This template can then be used when defining an output selector
       line. It will result in something like "/var/log/system-
       localhost.log"

   Template options
       The <options> part is optional. It carries options influencing
       the template as whole.  See details below. Be sure NOT to mistake
       template options with property options - the later ones are
       processed by the property replacer and apply to a SINGLE
       property, only (and not the whole template).

       Template options are case-insensitive. Currently defined are:

              sql    format the string suitable for a SQL statement in
                     MySQL format. This will replace single quotes ("'")
                     and the backslash character by their backslash-
                     escaped counterpart ("´" and "\") inside each
                     field. Please note that in MySQL configuration, the
                     NO_BACKSLASH_ESCAPES mode must be turned off for
                     this format to work (this is the default).

              stdsql format the string suitable for a SQL statement that
                     is to be sent to a standards-compliant sql server.
                     This will replace single quotes ("'") by two single
                     quotes ("''") inside each field.  You must use
                     stdsql together with MySQL if in MySQL
                     configuration the NO_BACKSLASH_ESCAPES is turned
                     on.

       Either the sql or stdsql option MUST be specified when a template
       is used for writing to a database, otherwise injection might
       occur. Please note that due to the unfortunate fact that several
       vendors have violated the sql standard and introduced their own
       escape methods, it is impossible to have a single option doing
       all the work.  So you yourself must make sure you are using the
       right format.  If you choose the wrong one, you are still
       vulnerable to sql injection.

       Please note that the database writer *checks* that the sql option
       is present in the template. If it is not present, the write
       database action is disabled.  This is to guard you against
       accidental forgetting it and then becoming vulnerable to SQL
       injection. The sql option can also be useful with files -
       especially if you want to import them into a database on another
       machine for performance reasons. However, do NOT use it if you do
       not have a real need for it - among others, it takes some toll on
       the processing time. Not much, but on a really busy system you
       might notice it ;)

       The default template for the write to database action has the sql
       option set.

   Template examples
       Please note that the samples are split across multiple lines. A
       template MUST NOT actually be split across multiple lines.

       A template that resembles traditional syslogd file output:

              $template TraditionalFormat,"%timegenerated% %HOSTNAME%
              %syslogtag%%msg:::drop-last-lf%\n"

       A template that tells you a little more about the message:

              $template
              precise,"%syslogpriority%,%syslogfacility%,%timegenerated%,%HOSTNAME%,
              %syslogtag%,%msg%\n"

       A template for RFC 3164 format:

              $template RFC3164fmt,"<%PRI%>%TIMESTAMP% %HOSTNAME%
              %syslogtag%%msg%"

       A template for the format traditionally used for user messages:

              $template usermsg," XXXX%syslogtag%%msg%\n\r"

       And a template with the traditional wall-message format:

              $template wallmsg,"\r\n\7Message from syslogd@%HOSTNAME%
              at %timegenerated%"

       A template that can be used for writing to a database (please
       note the SQL template option)

              $template MySQLInsert,"insert iut, message, receivedat
              values ('%iut%', '%msg:::UPPERCASE%',
              '%timegenerated:::date-mysql%') into systemevents\r\n",
              SQL

              NOTE 1: This template is embedded into core application
              under name StdDBFmt , so you don't need to define it.

              NOTE 2: You have to have MySQL module installed to use
              this template.

OUTPUT CHANNELS         top

       Output Channels are a new concept first introduced in rsyslog
       0.9.0. As of this writing, it is most likely that they will be
       replaced by something different in the future.  So if you use
       them, be prepared to change you configuration file syntax when
       you upgrade to a later release.

       Output channels are defined via an $outchannel directive. It's
       syntax is as follows:

              $outchannel name,file-name,max-size,action-on-max-size

       name is the name of the output channel (not the file), file-name
       is the file name to be written to, max-size the maximum allowed
       size and action-on-max-size a command to be issued when the max
       size is reached. This command always has exactly one parameter.
       The binary is that part of action-on-max-size before the first
       space, its parameter is everything behind that space.

       Keep in mind that $outchannel just defines a channel with "name".
       It does not activate it.  To do so, you must use a selector line
       (see below). That selector line includes the channel name plus
       ":omfile:$" in front of it. A sample might be:

              *.* :omfile:$mychannel

PROPERTY REPLACER         top

       The property replacer is a core component in rsyslogd's output
       system. A syslog message has a number of well-defined properties
       (see below). Each of this properties can be accessed and
       manipulated by the property replacer. With it, it is easy to use
       only part of a property value or manipulate the value, e.g. by
       converting all characters to lower case.

   Accessing Properties
       Syslog message properties are used inside templates. They are
       accessed by putting them between percent signs. Properties can be
       modified by the property replacer. The full syntax is as follows:

              %propname:fromChar:toChar:options%

       propname is the name of the property to access.  It is case-
       sensitive.

   Available Properties
       msg    the MSG part of the message (aka "the message" ;))

       rawmsg the message exactly as it was received from the socket.
              Should be useful for debugging.

       HOSTNAME
              hostname from the message

       FROMHOST
              hostname of the system the message was received from (in a
              relay chain, this is the system immediately in front of us
              and not necessarily the original sender)

       syslogtag
              TAG from the message

       programname
              the "static" part of the tag, as defined by BSD syslogd.
              For example, when TAG is "named[12345]", programname is
              "named".

       PRI    PRI part of the message - undecoded (single value)

       PRI-text
              the PRI part of the message in a textual form (e.g.
              "syslog.info")

       IUT    the monitorware InfoUnitType - used when talking to a
              MonitorWare backend (also for phpLogCon)

       syslogfacility
              the facility from the message - in numerical form

       syslogfacility-text
              the facility from the message - in text form

       syslogseverity
              severity from the message - in numerical form

       syslogseverity-text
              severity from the message - in text form

       timegenerated
              timestamp when the message was RECEIVED. Always in high
              resolution

       timereported
              timestamp from the message. Resolution depends on what was
              provided in the message (in most cases, only seconds)

       TIMESTAMP
              alias for timereported

       PROTOCOL-VERSION
              The contents of the PROTOCOL-VERSION field from IETF draft
              draft-ietf-syslog-protocol

       STRUCTURED-DATA
              The contents of the STRUCTURED-DATA field from IETF draft
              draft-ietf-syslog-protocol

       APP-NAME
              The contents of the APP-NAME field from IETF draft draft-
              ietf-syslog-protocol

       PROCID The contents of the PROCID field from IETF draft draft-
              ietf-syslog-protocol

       MSGID  The contents of the MSGID field from IETF draft draft-
              ietf-syslog-protocol

       $NOW   The current date stamp in the format YYYY-MM-DD

       $YEAR  The current year (4-digit)

       $MONTH The current month (2-digit)

       $DAY   The current day of the month (2-digit)

       $HOUR  The current hour in military (24 hour) time (2-digit)

       $MINUTE
              The current minute (2-digit)

       Properties starting with a $-sign are so-called system
       properties. These do NOT stem from the message but are rather
       internally-generated.

   Character Positions
       FromChar and toChar are used to build substrings. They specify
       the offset within the string that should be copied. Offset
       counting starts at 1, so if you need to obtain the first 2
       characters of the message text, you can use this syntax:
       "%msg:1:2%". If you do not wish to specify from and to, but you
       want to specify options, you still need to include the colons.
       For example, if you would like to convert the full message text
       to lower case, use "%msg:::lowercase%". If you would like to
       extract from a position until the end of the string, you can
       place a dollar-sign ("$") in toChar (e.g. %msg:10:$%, which will
       extract from position 10 to the end of the string).

       There is also support for regular expressions.  To use them, you
       need to place a "R" into FromChar.  This tells rsyslog that a
       regular expression instead of position-based extraction is
       desired. The actual regular expression must then be provided in
       toChar. The regular expression must be followed by the string
       "--end". It denotes the end of the regular expression and will
       not become part of it.  If you are using regular expressions, the
       property replacer will return the part of the property text that
       matches the regular expression. An example for a property
       replacer sequence with a regular expression is: "%msg:R:.*Sev:.
       \(.*\) \[.*--end%"

       Also, extraction can be done based on so-called "fields". To do
       so, place a "F" into FromChar. A field in its current definition
       is anything that is delimited by a delimiter character. The
       delimiter by default is TAB (US-ASCII value 9). However, if can
       be changed to any other US-ASCII character by specifying a comma
       and the decimal US-ASCII value of the delimiter immediately after
       the "F". For example, to use comma (",") as a delimiter, use this
       field specifier: "F,44".  If your syslog data is delimited, this
       is a quicker way to extract than via regular expressions
       (actually, a *much* quicker way). Field counting starts at 1.
       Field zero is accepted, but will always lead to a "field not
       found" error. The same happens if a field number higher than the
       number of fields in the property is requested. The field number
       must be placed in the "ToChar" parameter. An example where the
       3rd field (delimited by TAB) from the msg property is extracted
       is as follows: "%msg:F:3%". The same example with semicolon as
       delimiter is "%msg:F,59:3%".

       Please note that the special characters "F" and "R" are case-
       sensitive. Only upper case works, lower case will return an
       error. There are no white spaces permitted inside the sequence
       (that will lead to error messages and will NOT provide the
       intended result).

   Property Options
       Property options are case-insensitive. Currently, the following
       options are defined:

       uppercase
              convert property to lowercase only

       lowercase
              convert property text to uppercase only

       drop-last-lf
              The last LF in the message (if any), is dropped.
              Especially useful for PIX.

       date-mysql
              format as mysql date

       date-rfc3164
              format as RFC 3164 date

       date-rfc3339
              format as RFC 3339 date

       escape-cc
              replace control characters (ASCII value 127 and values
              less then 32) with an escape sequence. The sequence is
              "#<charval>" where charval is the 3-digit decimal value of
              the control character. For example, a tabulator would be
              replaced by "#009".

       space-cc
              replace control characters by spaces

       drop-cc
              drop control characters - the resulting string will
              neither contain control characters, escape sequences nor
              any other replacement character like space.

QUEUED OPERATIONS         top

       Rsyslogd supports queued operations to handle offline outputs
       (like remote syslogd's or database servers being down). When
       running in queued mode, rsyslogd buffers messages to memory and
       optionally to disk (on an as-needed basis). Queues survive
       rsyslogd restarts.

       It is highly suggested to use remote forwarding and database
       writing in queued mode, only.

       To learn more about queued operations, see the HTML
       documentation.
