Performance alerts are triggered by threshold violations, reported by application
services. Active alerts reflect an ongoing application service performance issue.
You can edit these thresholds, based on your system monitoring requirements.
A critical, or warning alert, that is active, indicates there has
been a sustained threshold violation for over five minutes. A subsequent alert is
triggered once another threshold is crossed (either an increase or decrease in
severity, or cleared). To ensure that conditions are improving, an alert for
declining severity (critical to warning) or a cleared alert, is triggered only when
the value is sustained for five minutes at ten percent below the threshold value.
For example, if a threshold value is configured for greater than 60 percent, a
declining severity must be sustained at 54 percent or less to trigger an alert.
