PCP(1)PCP(1)NAME
pcp - summarize a Performance Co-Pilot (PCP) installation
SYNOPSIS
pcp [-p] [-a archive] [-h host] [-n pmnsfile]
DESCRIPTION
The pcp command summarizes the status of a Performance Co-Pilot (PCP)
installation. The report includes: the OS version, a summary of the
hardware inventory, the local timezone, details of valid PCP licenses,
the PCP software version, the state of the pmcd(1) process and associ‐
ated Performance Metrics Domain Agents (PMDAs), as well as information
about any PCP archive loggers (pmlogger(1)) and PCP inference engines
(pmie(1)) that are running.
For more general information about PCP, refer to PCPIntro(1).
With no arguments, pcp reports on the local host, however the following
options are accepted:
-a archive
Report the PCP configuration as described in the PCP archive log
archive.
-h host
Report the PCP configuration on host rather than the localhost.
-n pmnsfile
Load an alternative Performance Metrics Name Space (pmns(4))
from the file pmnsfile.
-p Display pmie performance information - counts of rules evaluat‐
ing to true, false, or indeterminate, as well as the expected
rate of rule calculation, for each pmie process running on the
default host. Refer to the individual metric help text for full
details on these values.
All of the displayed values are performance metric values and further
information for each can be obtained using the command:
$ pminfo -dtT metric
The complete set of metrics required by pcp to produce its output is
contained in $PCP_VAR_DIR/config/pmlogger/config.pcp.
When displaying running pmlogger instances, as a space-saving measure
pcp will display a relative path to the archive being created if that
archive is located below a pcplog subdirectory, otherwise the full
pathname is displayed (the PCP log rotation and periodic pmlogger
checking facilities support the creation of archives below
$PCP_LOG_DIR/pmlogger/<hostname>).
A similar convention is used for trimming the amount of information
displayed for running pmie instances, where configuration files below
$PCP_VAR_DIR/config will be displayed in truncated form.
FILES
$PCP_VAR_DIR/config/pmlogger/config.pcp
pmlogger configuration file for collecting all of the metrics
required by pcp.
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(4).
SEE ALSOPCPIntro(1), pmcd(1), pmie(1), pmlogger(1), pcp.conf(4) and pcp.env(4).
DIAGNOSTICS
pcp will terminate with an exit status of 1 if pmcd on the target host
could not be reached or the archive could not be opened, or 2 for any
other error.
