## Symptoms

- * When viewing the CPU status in the SmartView Monitor, the average consumption for all cores is significantly lower than the consumption per core.
* SNMP OID 1.3.6.1.4.1.2620.1.6.7.2.4 (average for all cores) show low value, while SNMP OID .3.6.1.4.1.2620.1.6.7.5.1.5.x (per core) show similar results to the output of "top".
* After a reboot issue does not occur, but comes back again after a few weeks / months.

## Cause

SNMP OID 1.3.6.1.4.1.2620.1.6.7.2.4 and the smartview monitor are checking the CPU status not according to "top", but according to the /proc/stat file.

The issue can be frequent due to:

- Lots of software interrupts (soft IRQ), e.g. big network traffic on Security Gateway.

- Multiple CPUs, due to the summarization of all CPU's soft IRQ parameter.

proc/stat parameters are counted as CPUs ticks (1/100 the second) when it reaches unsigned 32bit number it will be truncated, these parameters are zeroed after machine's reset.
