       pmlogger_daily_report  -  write  Performance  Co-Pilot  daily summary

SYNOPSIS         top

       $PCP_BINADM_DIR/pmlogger_daily_report [-a archivefile] [-f
       outputfile] [-h hostname] [-l logfile] [-o directory] [-p] [-t
       interval] [-A] [-V] [--help]

DESCRIPTION         top

       pmlogger_daily_report and the associated systemd(1) services write
       daily performance summary reports, much like those produced by
       sadc(1) and the sa2(8) utility.

       All of the command line arguments are optional and intended to be
       self explanatory.  The service is not enabled by default.  If the
       service is enabled and no arguments are specified,
       pmlogger_daily_report will be run by systemd at 2am each morning and
       write a performance summary report named sarXX (where XX is
       yesterdays day-of-the-month, wrapping to the previous month if today
       is the 1st).  The outputfile may be changed with the -f option.  The
       report will be written to the $PCP_LOG_DIR/sa directory by default,
       but this may be changed with the -o option to a different directory.

       If the -a option is not given, the default input archivefile is
       $PCP_LOG_DIR/pmlogger/HOSTNAME/YYYYMMDD, where HOSTNAME defaults to
       the local hostname (may be changed with the -h option) and YYYYMMDD
       is the base name of yesterdays merged archive, as produced by
       pmlogger(1) and the pmlogger_daily(1) scripts.  If archivefile is a
       directory, then pmlogger_daily_report will use all PCP archives found
       in that directory to write the report (this is known as multi-archive
       mode, and may be considerably slower than specifying a single archive
       as the input).

       Note that there are suffciently flexible command line options for
       pmlogger_daily_report to be used to read any archivefile and write
       the report to any output directory.

       If the -p option is specified then the status of the daily processing
       is polled and if the report has not been done in the last 24 hours
       then it is done now.  The intent is to have pmlogger_daily_report
       called regularly with the -p option (at 30 mins past the hour, every
       hour in the default cron(8) set up) to ensure daily processing
       happens as soon as possible if it was missed at the regularly
       scheduled time (which is 02:00 by default), e.g. if the system was
       down or suspended at that time.

       With the -p option, pmlogger_daily_report simply exits if the
       previous day's processing has already been done.

       The reports themselves are created by the pmrep(1) utility using its
       default configuration file, see pmrep.conf(5).  The pmrep(1)
       configuration entries used to write the reports is currently
       hardwired into the pmlogger_daily_report script.

       Finally, the input archives must contain sufficient metrics as needed
       by pmrep(1) to write the report.  On platforms that support it, the
       pcp-zeroconf package configures PCP logging as required for this -
       hence pmlogger_daily_report should be used with the pmlogger(1)
       configuration that is set up by pcp-zeroconf.  As the name suggests,
       pcp-zeroconf requires no additional configuration after installation
       in order to capture the required archives needed by

       In order to ensure that mail is not unintentionally sent when this
       script is run by systemd(1), diagnostics are always sent to a log
       file.  By default, this file is
       $PCP_LOG_DIR/pmlogger/pmlogger_daily_report.log but this can be
       changed using the -l option.  If this log file already exists when
       the script starts, it will be renamed with a .prev suffix
       (overwriting any log file saved earlier) before diagnostics are
       generated to the log file.

       The output from the execution of the script may be extended using the
       -V option which enables verbose tracing of activity.  By default the
       script generates no log output unless some error or warning condition
       is encountered.


       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).
