Performance related issues with monitored asset

Spontaneous errors occur during specific times of the day or other patterns occur, such as when backup starts or large queries run in a database on the monitored asset.

Cause

The monitored asset may be unable to complete requests from Network Monitor since it's busy performing other tasks. The problem can also be network bandwidth related. For example monitoring assets over an VPN connection can severely degrade network performance and latency. The error messages can vary but most commonly they are all related to RPC failures.

Resolution/workarounds

• Lower the test frequency to 300 seconds
• Set the Alarm generation value to at least 5 to filter out false positives
• Use the Alarm filtering features in the monitor to filter out non-threshold errors.
• If low network bandwidth or high network latency is a factor, a gateway can be placed closer to the monitored asset. A gateway uses only a fraction of the network bandwidth that a normal test does.
