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

Cpu Util Interval Statistics


The following fields are displayed:

system cpuUtilCurrentStatistics Parameters

ParameterDescription
NumberA sequence number which identifies the interval for the set of statistics.
CE NameSpecifies the configured SBC server name.
CpuSpecifies the CPU number.
Interval ValidA 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.
  • False
  • True
TimeThe system up time when the interval statistics were collected.
AverageThe average CPU percentage utilization for this interval.
HighThe high CPU percentage utilization for this interval.
LowThe 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.
