NAME
pmdasimple - simple performance metrics domain agent (PMDA)
SYNOPSIS
$PCP_PMDAS_DIR/simple/pmdasimple [-d domain] [-i port] [-l logfile] [-p] [-u socket] [-U
username]
DESCRIPTION
pmdasimple is a simple Performance Metrics Domain Agent (PMDA) which exports a small
number of synthetic performance metrics.
The simple PMDA is shipped as source code and is designed to be an aid for PMDA
developers. In terms of code size and features, it is more complex than the trivial PMDA,
about the same as the txmon PMDA and less complex than the sample PMDA. The source for
the simple PMDA is a good template from which production, customized PMDAs can be
developed.
A brief description of the pmdasimple 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.
-i Expect PMCD to connect to pmdasimple on the specified TCP/IP port. port may be a
port number or port name.
-l Location of the log file. By default, a log file named simple.log is written in the
current directory of pmcd(1) when pmdasimple 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.
-p Expect PMCD to create a pipe and the connection to pmdasimple is via standard input
and standard output. This is the default connection mode.
-u Expect PMCD to connect to pmdasimple on the Unix domain socket named socket.
-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.
At most one of the options -i, -p and -u may be specified.
INSTALLATION
If you want access the names, help text and values for the simple performance metrics, do
the following as root:
# cd $PCP_PMDAS_DIR/simple
# ./Install
If you want to undo the installation, do the following as root:
# cd $PCP_PMDAS_DIR/simple
# ./Remove
pmdasimple 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 pmdasimple online using onworks.net services
