N.5 Troubleshoot OVP Results
The following list provides suggestions for troubleshooting OVP test failures:
• The OVP issues a test failure if CPU usage on one or more nodes is found to be over 10 percent. In
that case, use the top command to determine what processes are running and consuming CPU
resources.
• CPU usage might hit a spike if the system is in a metrics collection phase. In that case, run the OVP
again to see if the spike is a one-time instance or if the problem is persistent. If the problem is persistent,
use the top command to determine what processes are running and consuming CPU resources.
• The OVP issues a test failure if memory usage on the compute nodes is more than 25 percent. In that
case, log in to the compute node and use the top command to determine what processes are running
and consuming memory.

<<Starting on lsfhost.localdomain>>
The following node has memory usage more than 25%:
n3: memory usage is 34.38%, 12.08% of which is cache
--- FAILED ---
• The OVP issues a test failure when a node (in this example, n16) has values more than three standard
deviations from the mean. In this case, the failure could be a result of a loose cable on node n16.
