<process_filter>.add-pattern "pattern"
Restrict instrumentation to only a specific node path pattern as given by the pattern argument. The pattern can be a simple string just naming a process, e.g., "grep", or it can be more precise, like "pid=103,tid=103". For more information about node path patterns see the Analyzer User Guide. The filter uses os-awareness to automatically enable measurements for the tool when the given pattern matches the currently running process/thread on a processor. Similarly, disable measurement for the tool on the processor when the process/thread stops executing. Note that one single pattern can match several processes or threads. More than one pattern can be given by using this command several times, then the union of all patterns will be used.
