PROGRAM:
NAME
pmdatrivial - trivial performance metrics domain agent (PMDA)
SYNOPSIS
$PCP_PMDAS_DIR/trivial/pmdatrivial [-d domain] [-l logfile] [-U username]
DESCRIPTION
pmdatrivial is the simplest possible Performance Metrics Domain Agent (PMDA) which exports
a single performance metric, the time in seconds since the 1st of January, 1970.
The trivial PMDA is shipped as source code and is designed to be an aid for PMDA
developers.
A brief description of the pmdatrivial 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.
-l Location of the log file. By default, a log file named trivial.log is written in the
current directory of pmcd(1) when pmdatrivial 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 trivial performance metrics,
do the following as root:
# cd $PCP_PMDAS_DIR/trivial
# ./Install
If you want to undo the installation, do the following as root:
# cd $PCP_PMDAS_DIR/trivial
# ./Remove
pmdatrivial 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.
Use pmdatrivial online using onworks.net services
