NAME
pcp - summarize a Performance Co-Pilot (PCP) installation
SYNOPSIS
pcp [-p] [-a archive] [-h host] [-n pmnsfile] [host]
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 associated
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 PCPIn
tro(1).
With no arguments, pcp reports on the local host, however
the following options are accepted:
-a Report the PCP configuration as described in the
PCP archive log archive.
-h Report the PCP configuration on host rather than
the localhost.
-n Load an alternative Performance Metrics Name Space
(PMNS(4)) from the file pmnsfile.
-p Display pmie performance information - counts of
rules evaluating 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/con
fig.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
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 dis
played 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).

Relevant information is also available from the on-line
PCP Tutorial. Provided the pcp.man.tutorial subsystem
from the PCP images has been installed, access the URL

browser.
INDIGO MAGIC DESKTOP
Many PCP applications can be launched from the PerfTools
page of the IRIX Interactive Desktop Icon Catalog.
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.
