After gaining experience with the VMware Smart Assurance deployment, adjusting performance thresholds might reduce the number of inappropriate alarms. Devices might trigger alarms during normal operation because of performance thresholds set inappropriately low. Review all performance-related alarms that were triggered by conditions that did not represent actual or potential failures and adjust the threshold to avoid repetition of the alarm.
Conversely, failures of some devices might be preceded by performance degradation that does not trigger an alarm. Once again, review any failures that might be preceded by degraded performance and adjust the thresholds to detect these changes appropriately.
