PROGRAM:
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 daemon 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.
