PMIESTATUS(1) General Commands Manual PMIESTATUS(1)NAME
pmiestatus - display information from pmie stats file
SYNOPSIS
pmiestatus statsfile [...]
DESCRIPTION
pmiestatus displays information used to identify a running pmie process. It is mostly used by pmie_check and pmie_daily when they hunt for
instances of pmie to check against the control file.
FILES
$PCP_TMP_DIR/pmie/*
pmie stats files
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 configura-
tion file, as described in pcp.conf(5).

PMDASUMMARY(1) General Commands Manual PMDASUMMARY(1)NAME
pmdasummary - summary performance metrics domain agent (PMDA)
SYNOPSIS
$PCP_PMDAS_DIR/summary/pmdasummary [-d domain] [-h helpfile] [-l logfile] [-U username] pmie-command-line
DESCRIPTION
pmdasummary is a Performance Metrics Domain Agent (PMDA) which derives performance metrics values from values made available by other
PMDAs. pmdasummary consists of two processes:
pmie process
The inference engine for performance values pmie(1) is used to periodically sample values for the base metrics and compute the
derived values. This process is launched with the given pmie-command-line arguments by the main process, described below.
main process
The main process reads and buffers the values computed by pmie(1) and makes them available to the performance metrics collector dae-
mon pmcd(1).
A brief description of the pmdasummary command line options follows:
-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.
-h This option specifies an alternative help text file helpfile for describing the metrics that pmdasummary represents.
-l Location of the log file. By default, a log file named summary.log is written in the current directory of pmcd(1) when pmdasummary 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.
-U User account under which to run the agent. The default is the unprivileged "pcp" account in current versions of PCP, but in older
versions the superuser account ("root") was used by default.
INSTALLATION
If you want access to the names, help text and values for the summary performance metrics, do the following as root:
# cd $PCP_PMDAS_DIR/summary
# ./Install
If you want to undo the installation, do the following as root:
# cd $PCP_PMDAS_DIR/summary
# ./Remove
pmdasummary 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.
