Probably worth a small patch to ps_mem.py (which is more accurate per-process than other methods) to make it run continuosly and give you CSV output. Or a cron on ps_mem.py /var/log/mem.log (I'd patch this myself now, but I'm about to hit the road, so packing.) m -- martin.langh...@gmail.com mar...@laptop.org -- School Server Architect - ask interesting questions - don't get distracted with shiny stuff - working code first - http://wiki.laptop.org/go/User:Martinlanghoff ___ Server-devel mailing list Server-devel@lists.laptop.org http://lists.laptop.org/listinfo/server-devel
Re: [Server-devel] logging performance
Sameer, Have you looked at RRDtool ? It is my understanding it can log at 1 second intervals. You can find it at http://oss.oetiker.ch/rrdtool/index.en.html along with tutorials. Some good example scripts using RRDtool can be found at http:// computingplugs.com/index.php/SheevaPlug_Real_time_Statistics#Scripts Scroll up on that page to see live graphical output from the scripts. rihowa...@gmail.com linux - the best things in life are free On Jul 15, 2009, at 12:23 PM, Sameer Verma wrote: Any suggestions on how to log data on RAM and CPU usage on the XS?
