Hello Siva, During one of our load test we noticed nearly 40% of memory was utilized by swap. But we couldn't confirm the process responsible for swap utilization. As everybody aware that swap utilization will have an adverse effect on the application performance. We experimented few tools and 1. Top command doesn't provide the utilization by process. 2. To use pmap we need to provide the process id of each process.
I found a tool exmap which gives a clear picture of what happens during a load test means the swap utilization and the process and shared libraries Responsible for that unfortunately we aren't able to build the tool for Redhat. Exmap libraries are created mostly for debian and ubuntu distros. Exmap: http://www.berthels.co.uk/exmap/faq.html Source: http://packages.debian.org/sid/exmap-modules-source Thanks Sattish. -----Original Message----- From: Sivakumar Gopalan Sent: Tuesday, March 24, 2009 2:21 PM To: Sattish Vaasudevan Subject: RE: [Ilugc] Swap utilization Tell me what you need, I will see if I can write a tool for you.
