Level: Critical

Purpose: Alert Errigal engineers to excessive CPU usage on an application server. Excessive CPU usage over a period of time is indicative of an underlying problem that should be investigated.

Scenario: CPU usage over period of time has been very high.

Resolution: Log onto the server in question, run a top command to determine process using the most CPU. This will identify which application is eating all the CPU. This could be anything from alarmCache, EMS/Snmp Manager to a long running query in the database.

Manual Action Steps:

Run the below command on the server:
top

Check number of CPUs

 egrep 'core id|physical id' /proc/cpuinfo | tr -d "\n" | sed s/physical/\\nphysical/g | grep -v '^$' | sort | uniq | wc -l

Examine the process with the highest CPU usage, also the load averages at the top. Please note the number of cores matters when using the load averages.
