High system column (vmstat) on the web server


Here is the output from vmstat 5 command on our web server:


Looks like system column (sy) is too high and I’m trying to figure out what could causing that…

Is there any tools I can look at to trace it?

I would really appreciate any suggestions!


Hi there,

This could mean a lots of things.

At first I think you should try to run top -d1 to see which application of yours is eating up all your cpu.


Looks like it mostly httpd (Apache)…Is it possible for Apache to cause high system usage? I was thinking it should affect user column…
