NAME         top

       pmieconf - display and set configurable pmie rule variables

SYNOPSIS         top

       pmieconf [-cFv?]  [-f file] [-r rulepath] [command [args...]]

DESCRIPTION         top

       pmieconf is a utility for viewing and configuring variables from
       generalized pmie(1) rules.  The set of generalized rules is read in
       from rulepath, and the output file produced by pmieconf is a valid
       input file for pmie.

OPTIONS         top

       The available command line options are:

       -c   When run from automated pmie setup processes, this option is
            used to add a specific message and timestamp indicating that
            this is the case.  It is not appropriate when using the tool

       -f file, --config=file
            Any rule modifications resulting from pmieconf manipulation of
            variable values will be written to file.  The default value of
            file is dependent on the user ID - for the root user, the file
            $PCP_SYSCONF_DIR/pmie/config.pmie is used, for other users the
            default is $HOME/.pcp/pmie/config.pmie.

       -F   Forces the pmieconf output file to be created (or updated),
            after which pmieconf immediately exits.

       -r rulepath, --rules=rulepath
            Allows the source of generalized pmie rules to be changed -
            rulepath is a colon-delimited list of pmieconf(5) rule files
            and/or subdirectories.  The default value for rulepath is
            $PCP_VAR_DIR/config/pmieconf.  Use of this option overrides the
            PMIECONF_PATH environment variable which has a similar function.

       -v, --verbose
            Enable verbose mode.  associated variables will be displayed.
            This is the complete list of variables which affects any given
            rule (by default, global variables are not displayed with the

       -?, --help
            Display usage message and exit.

       The pmieconf commands allow information related to the various rules
       and configurable variables to be displayed or modified.  If no
       pmieconf commands are presented on the command line, pmieconf prompts
       for commands interactively.


       The pmieconf command language is described here:

       help  [ { . | all | global | <rule> | <group> } [<variable>] ]
               Without arguments, the help command displays the syntax for
               all of the available pmieconf commands.  With one argument, a
               description of one or more of the generalized rules is
               displayed.  With two arguments, a description of a specific
               variable relating to one or more of the generalized rules is

       rules  [ enabled | disabled ]
               Display the name and short summary for all of the generalized
               rules found on rulepath.  Each of the rule names can be used
               in place of the keyword <rule> in this command syntax
               description.  The enabled and disabled options can be used to
               filter the set of rules displayed to just those which are
               enabled or disabled respectfully.

       groups  Display the name of all of the rule groups that were found on
               rulepath.  Each of the group names can be used in place of
               the keyword <group> in this command syntax description, which
               applies the command to all rules within the rule group.

       status  Display status information relating to the current pmieconf
               session, including a list of running pmie processes which are
               currently using file.

       enable  { . | all | <rule> | <group> }
               Enables the specified rule or group of rules.  An enabled
               rule is one which will be included in the pmie configuration
               file generated by pmieconf.  Any enabled "actions" will be
               appended to the rule's "predicate", in a manner conforming to
               the pmie syntax ("actions" can be viewed using the list
               global command, described below).

       disable  { . | all | <rule> | <group> }
               Disables the specified rule or group of rules.  If the rule
               was previously enabled, it will be removed from the pmie
               configuration file generated by pmieconf, and hence no longer
               evaluated when pmie is restarted (using pmieconf does not
               affect any existing pmie processes using file).

       list  { . | all | global | <rule> | <group> } [<variable>]
               Display the values for a specific rule variable; or for all
               variables of a rule, a rule group, all rules, or the global

       modify  { . | all | global | <rule> | <group> } <variable> <value>
               Enable, disable, or otherwise change the value for one or
               more rule variables.  This value must be consistent with the
               type of the variable, which can be inferred from the format
               of the printed value - e.g. strings will be enclosed in
               double-quotes, percentages have the ``%'' symbol appended,
               etc.  Note that certain rule variables cannot be modified
               through pmieconf - "predicate" and "help", for example.

       undo  { . | all | global | <rule> | <group> } [<variable>]
               Applicable only to a variable whose value has been modified -
               this command simply reverts to the default value for the
               given variable.

       quit    Save any changes made to file and then exit pmieconf.

       abort   Exit pmieconf immediately without saving any changes to file.

       Each of the commands above can be shortened by simply using the first
       character of the command name, and also ``?'' for help.

       Use of the all keyword causes the command to be applied to all of the
       rules.  The global keyword refers to those variables which are
       applied to every rule.  Such variables can be changed either globally
       or locally, for example:

         pmieconf> modify global delta "5 minutes"
         pmieconf> modify memory delta "1 minute"

       causes all rules to now be evaluated once every five minutes, except
       for rules in the "memory" group which are to be evaluated once per

       The ``.'' character is special to pmieconf - it refers to the last
       successfully used value of all, global, <rule> or <group>.

EXAMPLES         top

       Specify that all of the rules in the "memory" group should be

         pmieconf> modify memory enabled yes

       Change your mind, and revert to using only the "memory" rules which
       were enabled by default:

         pmieconf> undo memory enabled

       Specify that notification of rules which evaluate to true should be
       sent to syslogd(1):

         pmieconf> modify global syslog_action yes

       Specify that rules in the "per_cpu" group should use a different
       holdoff value to other rules:

         pmieconf> help global holdoff
           rule: global  [generic parameters applied to all rules]
            var: holdoff
           help: Once the predicate is true and the action is executed,
              this variable allows suppression of further action
              execution until the specified interval has elapsed.
              A value of zero enables execution of the action if
              the rule predicate is true at the next sample. Default
              units are seconds and common units are "second", "sec",
              "minute", "min" and "hour".

         pmieconf> modify per_cpu holdoff "1 hour"

       Lower the threshold associated with a particular variable for a
       specified rule:

         pmieconf> l cpu.syscall predicate
           rule: cpu.syscall  [High aggregate system call rate]
             predicate =
                  some_host (
                   ( kernel.all.syscall $hosts$ )
                     > $threshold$ count/sec * hinv.ncpu $hosts$

         pmieconf> m . threshold 7000

         pmieconf> l . threshold
           rule: cpu.syscall  [High aggregate system call rate]
                threshold = 7000

ENVIRONMENT         top

       The environment variable PMIECONF_PATH has a similar function to the
       -r option described above, and if set will be used provided no -r
       option is presented.


       Environment variables with the prefix PCP_ are used to parameterize
       the file and directory names used by PCP.  On each installation, the
       file /etc/pcp.conf contains the local values for these variables.
       The $PCP_CONF variable may be used to specify an alternative
       configuration file, as described in pcp.conf(5).
