NetAppESeries.PerformanceOverrides :: 2.1.0.1 (Management Pack)

Summary

There is a potential performance investigation that should happen for the volumes listed in the alert. Volume response times are measured in milliseconds and best model volume latency for a NetApp ESeries Storage Array. Volume response times are an ‘on the box’ measurement. This means the measurement is the amount of time the storage array takes to service the request from a particular host or application.

Use these override configurations to tune NetApp ESeries performance monitors. Available overrides are threshold, trace level, interval and timeout values.

Additional

Keep in mind that periodic operations like batch updating, backups and synchronizations can cause volume response time to elevate. Depending on the operation and the time of day it occurs, the elevated response time is completely normal and expected. For this reason NetApp recommends tuning volume response time thresholds from high to low until a reasonable response time for the particular workload is determined. If storage arrays have different workloads, it is recommended to override this monitor on an array basis. Or if a similar workload is expected across all storage arrays monitored by a single agent, then the NetApp.ESeries.PerformanceOverrides.xml file can be used to override performance thresholds for all storage arrays.
