Many months ago when a web application running in Tomcat on a Linux server experienced intermittent and severe performance problems I setup a cron task to record Tomcat free memory and operating system load average. I plotted these figures on a chart using JFreeChart and I was able to get huge insight into the problem which other tools failed to provide. I'd like to expand this script to record other potentially useful data which I can use as a baseline should problems arise in future. Besides load average and tomcat free memory -- what else should I record given that I'm running a pretty typical Java/Linux/Tomcat/MySQL server. The kind items that come to mind is network IO, disk IO, page fault rate.... BTW: what's the best way of getting the page fault rate? I can't find the right file in /proc for that. Thanks, Joe. -- fedora-devel-java-list mailing list fedora-devel-java-list@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/fedora-devel-java-list
