Use the
--metricsoption to collect custom perfCtl based metrics provided in the command line. MSR based events (aperf,mperf,irperf, andtsc) are not allowed to collect without at least one valid PMC event in the given metrics. In such a case, behavior will be undefined.While using the
--use-linux-perfflag, you cannot use the options-Cand-ptogether in Linux.All VM configurations have not been tested.
When collecting multiple metrics simultaneously, the profiler may sporadically report a Failed to Configure CountMode API error.
