Use the Cpu Util Interval Statistics window to view CPU utilization over a series of time intervals. To set the time interval and the number of statistic sets that are stored, refer to System - Interval Statistics.
On the SBC main screen, go to Monitoring > System > Category: Hardware Status > CPU > CPU Util Interval Statistics or
Monitoring > Dashboard > CPU > CPU Util Interval Statistics
All > System > CPU Util Interval Statistics
The Cpu Util Interval Statistics window is displayed.
The following fields are displayed:
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.
