From the SBC main screen, go to Monitoring > Dashboard > CPU > CPU Usage or
Monitoring > System > Category: Hardware Status > CPU Usage
The CPU Usage window displays.
The following entries are displayed:
The same entries are displayed in a chart format.
The CPU usage data is updated every five seconds.
For applications using Linux kernel version 3.16 or higher (for example, SBC v06.02.00 and higher), the output of the top
command displays wrong, and sometimes unrealistic, values about CPU utilization. This is a known issue with all 3.16 and higher kernels (refer to this CentOS page for more information).
Likewise, the information and graphs displayed in this EMA window may display wrong values of CPU utilization.
You can use top -H
or mpstat
commands to check the memory and CPU utilization.
