Making sense of cPanel's numbers...

[pepper_bg]

Hi,

We have a Linux instance with cPanel running on it. There are a couple of numbers the meaning of which I can't figure out:
- CPU Usage: 155.4%/100% CPU - at the same moment here top shows "Cpu(s): 2.9%us, 0.5%sy, 0.0%ni, 96.6%id" and uptime "2.0, 2.2, 2.2", so what Linux command do I run to get this number?
- HTTP Connections: 190/300 - this seems close to what I get when I run "netstat | grep http | wc" but can I be sure?

Appreciate your help...

The CPU numbers are derived directly from the top command. For example, this a segment of the top output from a running server:

top - 07:35:33 up 12 days, 22 min,  1 user,  load average: 0.48, 0.16, 0.07
Tasks: 108 total,   1 running, 107 sleeping,   0 stopped,   0 zombie
Cpu(s):  0.3%us,  0.0%sy,  0.0%ni, 99.7%id,  0.0%wa,  0.0%hi,  0.0%si,  0.0%st
Mem:   1024864k total,   963156k used,    61708k free,   152428k buffers
Swap:  2031608k total,       72k used,  2031536k free,   456220k cached

For a full explanation, you can type man top at the shell command prompt, and I also found the following explanations which break down each field in the output:

top - Linux Command - Unix Command
top - Linux command line to see the running processes in real time | Linux Operating System
The Linux top command | Unix Linux top cpu, memory usage | ps command | devdaily.com

The Apache information is derived from the output of this command:

# /usr/local/apache/bin/apachectl status

The output of that command is what is displayed in Main >> Server Status >> Apache Status. The number of HTTP connections is derived from that output, not from a netstat command.

Thanks for the reply, Jared!

Yes, I know top. Yet I don't see there percentages going above 100% (well, I do for the individual processes when in Irix mode but that is irrelevant here). To which number in top corresponds cPanel's CPU Usage?

Thanks...
