       pmdatxmon - txmon performance metrics domain agent (PMDA)

       $PCP_PMDAS_DIR/txmon/pmdatxmon [-d domain] [-l logfile] [-U username] tx_type ...
       $PCP_PMDAS_DIR/txmon/txrecord [-l]
       $PCP_PMDAS_DIR/txmon/txrecord tx_type servtime [tx_type servtime ... ]

       pmdatxmon is an example Performance Metrics Domain Agent (PMDA) which exports a small num-
       ber of performance metrics from a simulated transaction monitor.

       The txmon PMDA is shipped as both binary and source code and is designed to be an aid  for
       PMDA  developers; the txmon PMDA demonstrates how performance data can be exported from an
       application (in this case txrecord) to the PCP infrastructure via a shared memory segment.
       As  a  matter  of  convenience, pmdatxmon creates (and destroys on exit) the shared memory

       The tx_type arguments are arbitrary unique tags used  to  identify  different  transaction

       The  txrecord  application simulates the processing of one or more transactions identified
       by tx_type and with an observed service time of servtime .

       With the -l option, txrecord displays the current summary of the transaction activity from
       the shared memory segment.

       genload	is  a  shell and awk(1) script that acts as a front-end to txrecord to generate a
       constant load of simulated transaction activity.

       A brief description of the pmdatxmon 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 txmon.log is written  in  the
	    current  directory of pmcd(1) when pmdatxmon 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.

       If  you	want access to the names, help text and values for the txmon performance metrics,
       do the following as root:

	    # cd $PCP_PMDAS_DIR/txmon
	    # ./Install

       You will be prompted for the tx_type tags.

       If you want to undo the installation, do the following as root:

	    # cd $PCP_PMDAS_DIR/txmon
	    # ./Remove

       pmdatxmon 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.

       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 config-
       uration file, as described in pcp.conf(5).
