15 pmdatxmon is an example Performance Metrics Domain Agent (PMDA) which
16 exports a small number of performance metrics from a simulated transac‐
17 tion monitor.
18 The txmon PMDA is shipped as both binary and source code and is
20 designed to be an aid for PMDA developers; the txmon PMDA demonstrates
21 how performance data can be exported from an application (in this case
22 txrecord) to the PCP infrastructure via a shared memory segment. As a
23 matter of convenience, pmdatxmon creates (and destroys on exit) the
24 shared memory segment.
25 The tx_type arguments are arbitrary unique tags used to identify dif‐
27 ferent transaction types.
28 The txrecord application simulates the processing of one or more trans‐
30 actions identified by tx_type and with an observed service time of
31 servtime .
32 With the -l option, txrecord displays the current summary of the trans‐
34 action activity from the shared memory segment.
35 genload is a shell and awk(1) script that acts as a front-end to
37 txrecord to generate a constant load of simulated transaction activity.
38 A brief description of the pmdatxmon command line options follows:
40 -d It is absolutely crucial that the performance metrics domain num‐
42 ber specified here is unique and consistent. That is, domain
43 should be different for every PMDA on the one host, and the same
44 domain number should be used for the same PMDA on all hosts.
45 -l Location of the log file. By default, a log file named txmon.log
47 is written in the current directory of pmcd(1) when pmdatxmon is
48 started, i.e. $PCP_LOG_DIR/pmcd. If the log file cannot be cre‐
49 ated or is not writable, output is written to the standard error
50 instead.

53 If you want access to the names, help text and values for the txmon
54 performance metrics, do the following as root:
55 # cd $PCP_PMDAS_DIR/txmon
57 # ./Install
58 You will be prompted for the tx_type tags.
60 If you want to undo the installation, do the following as root:
62 # cd $PCP_PMDAS_DIR/txmon
64 # ./Remove
65 pmdatxmon is launched by pmcd(1) and should never be executed directly.
67 The Install and Remove scripts notify pmcd(1) when the agent is
68 installed or removed.

84 Environment variables with the prefix PCP_ are used to parameterize the
85 file and directory names used by PCP. On each installation, the file
86 /etc/pcp.conf contains the local values for these variables. The
87 $PCP_CONF variable may be used to specify an alternative configuration
88 file, as described in pcp.conf(4).
