pmdarsyslog

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

To uninstall, 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

$PCP_LOG_DIR/rsyslog/stats

named pipe containing statistics exported from rsyslog, usually created by the PMDA Install script.

$PCP_PMDAS_DIR/rsyslog/rsyslog.conf

optional configuration file for pmdarsyslog

$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

PCP Environment

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).
