We running a few cPanel-based hosts, and for two of them "CPU/Memory/MySQL Usage " (which is very handy) at WHM are empty. It lists set of users (mysql, mailnull, set of usernames that used by suexec to start php fcgi process), but both "%CPU" and "%MEM" fields are zeroes.
I found that those two servers had not sysstat package installed (which contains sar and iostat commands) while it was installed on others. I thought maybe cpanel uses sar/iostat to collect stats. But after I installed it and restarted cpanel service, nothing changes.
Please advice.
(Also english is not my native, I`m from Russia, so If my language is broken -- sorry.)
