I forgot to mention that if you are interested in RPC operation counts and times, the xstat_fs_test RPC metrics (-collID 2) are adequate and work out of the box, but they are only available for fileservers. Similarly, xstat_cm_test also reports RPC operation counts and times, but only for cache managers. These metrics have some other limitations as well. The lesser-known Rx RPC statistics (aka RPCSTATS, RXSTATS) have to be enabled, but they are easy to enable (via the --enable_processs_stats option or rxstat_enable_process command). I consider them superior to what's available via xstat_fs_test: - they are universal (work _almost_ the same for all OpenAFS components, with some cache manager quirks) - they are more accurate (they include some rx and dispatch overhead that xstat_* can't capture) - they record RPC metrics from both the server (RPCs received) and client (RPCs issued) perspective - they are remotely resettable (via rxstat_clear_process). - they support both process (server) and peer (client) granularity Regards, -- Mark Vitale mvit...@sinenomine.net _______________________________________________ OpenAFS-info mailing list OpenAFS-info@openafs.org https://lists.openafs.org/mailman/listinfo/openafs-info
