+ * app1.c
+ *
+ * Simple program to demonstrate use of the PCP trace performance metrics
+ * domain agent (PMDA(3)).  This agent needs to be installed before metrics
+ * can be made available via the performance metrics namespace (PMNS(4)),
+ * and the Performance Metrics Collector Daemon (PMCD(1)).
+ *
+ * Once this program is running, the trace PMDA metrics & instances can be
+ * viewed through PCP monitor tools such as pmchart(1), pmgadgets(1), and
+ * pmview(1).  To view the help text associated with each of these metrics,
+ * use:
+ *   $ pminfo -tT trace
