pmdarsyslog

PMDARSYSLOG(1)						       Performance Co-Pilot						    PMDARSYSLOG(1)

NAME

       pmdarsyslog - rsyslog (reliable and extended syslog) PMDA

DESCRIPTION

       pmdarsyslog is a Performance Metrics Domain Agent (PMDA) which exports metric values from the rsyslogd(8) server.  Further details about
       rsyslog can be found at http://www.rsyslog.com/.

INSTALLATION

       If you want access to the names and values for the rsyslog performance metrics, do the following as root:

	       # cd $PCP_PMDAS_DIR/rsyslog
	       # ./Install

       If you want to undo the installation, do the following as root:

	       # cd $PCP_PMDAS_DIR/rsyslog
	       # ./Remove

       pmdarsyslog is launched by pmcd(1) and should never be executed directly.  The Install and Remove scripts notify pmcd(1) when the agent is
       installed or removed.

       In order to use this agent, rsyslog stats gathering must be enabled.  This is done by adding the lines:

	       $ModLoad impstats
	       $PStatsInterval 5       # log every 5 seconds
	       syslog.info	       |/var/log/pcp/rsyslog/stats

       to your rsyslog.conf(5) configuration file after installing the PMDA.  Take care to ensure the syslog.info messages do not get logged in
       any other file, as this could unexpectedly fill your filesystem.  Syntax useful for this is syslog.!=info for explicitly excluding these.

FILES

       /var/log/pcp/rsyslog/stats
	   named pipe containing statistics exported from rsyslog, usually created by the PMDA Install script.

       $PCP_PMDAS_DIR/rsyslog/Install
	   installation script for the pmdarsyslog agent

       $PCP_PMDAS_DIR/rsyslog/Remove
	   undo installation script for the pmdarsyslog agent

       $PCP_LOG_DIR/pmcd/rsyslog.log
	   default log file for error messages from pmdarsyslog

SEE ALSO

       pmcd(1), rsyslog.conf(5), rsyslogd(8).
