SLACs documentation for their Perl module is pretty accessible: http://search.cpan.org/~alfw/AFS-Monitor-0.3.2/pod/afsmon_stats.pod You basically want to look at cache hits vs misses (both dcache & vcache). Those are the most helpful statistics. There is a lot of information out there about cache tuning -- feel free to ask more specific questions. I know somewhere there are some sample config files for afsmonitor, and I believe the old IBM docs have each field in afsmonitor documented (although there has almost certainly been some drift between those docs and what is present and supported in the code now). -- Steven Jenkins End Point Corporation http://www.endpoint.com/ _______________________________________________ OpenAFS-info mailing list OpenAFS-info@openafs.org https://lists.openafs.org/mailman/listinfo/openafs-info
