Hi, I'm looking for wisdom and advice here. I'm supporting an application running on Solaris, and it is experiencing performance problems during peak use times. I was asked to look at the OS and ascertain where the issue might be. If this was Windows, I would start by running perfmon for a day watching a standard set of counters and looking for numbers to be above certain thresholds (i.e. pages/sec higher than 2 consistently, %processor utilization above 80, etc). I gather in Solaris one runs vmstat, prstat, iostat, mpstat as a start. What I can't find is any documentation of what realistic thresholds are for the counters. So I have some lovely log files and not much idea where my problem really is. Suggestions? Are there good third-party utilities that might be installed here somewhere that I might not know about? (that's very possible - I'm new here) One thing I do know is that I have no baseline to compare to. There has been no previous performance monitoring. It's entirely possible that the application is misbehaving, but I need to know how - is it chewing up memory? Making too many calls to the DB and overloading the network?
Thanks, Pam _______________________________________________ Discuss mailing list [email protected] http://lopsa.org/cgi-bin/mailman/listinfo/discuss This list provided by the League of Professional System Administrators http://lopsa.org/
