pmtrace - command line performance instrumentation

pmtrace provides a simple command line interface to the trace Performance Metrics Domain Agent (PMDA) and
       the associated pcp_trace library.

       The  default pmtrace behavior is to provide point trace data to the trace PMDA, using the tag argument as
       the identifying name associated with each trace point.  The  tag  then  becomes  an  instance  identifier
       within the set of trace.point metrics.

       All are generated on standard error and are intended to be self-explanatory.

       The pmtrace exit status is always zero except when the -e option is in use, in which case the exit status
       of command is returned.

       Since  pmtrace  uses  the  libpcp_trace  library  routines,  the  environment  variables  PCP_TRACE_HOST,
       PCP_TRACE_PORT, and PCP_TRACE_TIMEOUT are all honored.  Refer to pmdatrace(3) for a detailed  description
       of the semantics of each.

pmtrace - command line performance instrumentation

       The available command line options are:

       -cvalue
            Allow an arbitrary counter value to be exported through the trace.count metrics.

       -ecommand
            Allow  an arbitrary command to be executed.  This command will be measured as a transaction since it
            has well defined start and end points.  The information is made available through the trace.transact
            metrics.

       -hhost
            Sent the trace data to the trace PMDA running on host, rather than the  localhost.   This  overrides
            use of the environment variable PCP_TRACE_HOST.

       -q   Suppress messages from a successful trace, so that pmtrace runs quietly.

       -Sstate
            Enable  internal debugging and tracing.  The value of state is a bit-wise combination of debug flags
            as defined in pmtracestate(3), and  may  be  specified  using  the  decimal  or  hexadecimal  syntax
            prescribed by strtol(3).

       -vvalue
            Allow an arbitrary floating point value to be exported through the trace.observe metrics.

       -?   Display usage message and exit.

       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 configuration file, as described in pcp.conf(5).
