pmdarpm is a Performance Metrics Domain Agent (PMDA) which extracts
performance metrics reflecting the state of the RPM package database
managed by rpm(1).
The rpm PMDA exports metrics that describe each package installed on
a system, as well as some cumulative totals. When the RPM database
changes the PMDA automatically detects this and uses a background
thread to asynchronously refresh its values.
A brief description of the pmdarpm command line options follows:
-C Verify the package iteration code by scanning the RPM database
once, then exiting. Only useful for problem diagnosis and
-d It is absolutely crucial that the performance metrics domain
number specified here is unique and consistent. That is, domain
should be different for every PMDA on the one host, and the same
domain number should be used for the same PMDA on all hosts.
-l Location of the log file. By default, a log file named rpm.log
is written in the current directory of pmcd(1) when pmdarpm is
started, i.e. $PCP_LOG_DIR/pmcd. If the log file cannot be
created or is not writable, output is written to the standard
-r Specify an alternate path to the RPM database (default is
-U User account under which to run the agent. The default is the
unprivileged "pcp" account.
If you want access to the names, help text and values for the rpm
performance metrics, do the following as root:
# cd $PCP_PMDAS_DIR/rpm
If you want to undo the installation, do the following as root:
# cd $PCP_PMDAS_DIR/rpm
pmdarpm 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.

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).
