PMDARPM(1) General Commands Manual PMDARPM(1)
pmdarpm - RPM packages performance metrics domain agent (PMDA)
$PCP_PMDAS_DIR/rpm/pmdarpm [-C] [-d domain] [-l logfile] [-r
path] [-U username]
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 testing.
-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 error instead.
-r Specify an alternate path to the RPM database (default is
/var/lib/rpm/Packages).
-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
# ./Install
If you want to undo the installation, do the following as root:
# cd $PCP_PMDAS_DIR/rpm
# ./Remove
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.
$PCP_PMCDCONF_PATH
command line options used to launch pmdarpm
$PCP_PMDAS_DIR/rpm/help
default help text file for the rpm metrics
$PCP_PMDAS_DIR/rpm/Install
installation script for the pmdarpm agent
$PCP_PMDAS_DIR/rpm/Remove
undo installation script for the pmdarpm agent
$PCP_LOG_DIR/pmcd/rpm.log
default log file for error messages and other information
from pmdarpm
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).
PCPIntro(1), pmcd(1), pcp.conf(5) and pcp.env(5).
