<p><b>New page</b></p><div>This procedure is used to check the CPU usage.<br><br />
Since this is a standard distribution of linux, customers can use other available commands.<br />
<br />
== Check CPU usage ==<br />
From the web interface you can see the CPU usage:<br><br />
Hosts -> Status -> Select Host -> Processor Usage tab<br />
<br />

<br><br />
<br />
From the [[Accessing_Device#SSH|SSH access]], here are the available commands. <br><br />
With the '''top''' command you can see the total CPU usage (and Memory usage) of the host:<br />
# top <br />
top - 14:16:25 up 22 days, 6:35, 1 user, load average: 0.00, 0.02, 0.06<br />

Here we see the CPU usage is at 99% idle.</div>Luc Morissette
