NAME


pmtrace - command line performance instrumentation

SYNOPSIS


pmtrace [-q] [-c value | -e command | -v value] [-h host] [-S state] tag

DESCRIPTION


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.

The -e option allows 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.

Trace data can be sent to the trace PMDA running on host, rather than the localhost, using
the -h option. This overrides use of the environment variable PCP_TRACE_HOST.

The -q option suppresses messages from a successful trace, so that pmtrace runs quietly.

The -c option allows an arbitrary counter value to be exported through the trace.count
metrics, while the -v option allows an arbitrary floating point value to be exported
through the trace.observe metrics

The -S option enables 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).

ENVIRONMENT


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.
