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.
| Parameter | Description |
|---|---|
| Number | A sequence number which identifies the interval for the set of statistics. |
| CE Name | Specifies the configured SBC server name. |
| Cpu | Specifies the CPU number. |
| Interval Valid | A setting of True indicates the interval contains valid data during the time interval. Each interval is for a configurable fixed time (default interval is 15 minutes) starting on the hour. For example, if the system starts at 12:05, the first interval at 12:15 will not be valid because it is less than the 15-minute interval. Subsequent intervals will be valid upon meeting the 15-minute time interval. System switch-overs also cause invalid intervals because data is lost during the interval.
|
| Time | The system up time when the interval statistics were collected. |
| Average | The average CPU percentage utilization for this interval. |
| High | The high CPU percentage utilization for this interval. |
| Low | The low CPU percentage utilization for this interval. |
Note
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.
