Defining Alert Conditions

Alert conditions define the logic that triggers an alert.

The alert condition reads like a sentence. In the example above, the condition is:

Set an alert on Server Load when the average goes above 0.96 for a duration of at least 5 minutes.

Condition to Measure (Set alert on)

Condition Type (When it)

  • Goes above: Alert fires if the incoming value exceeds the threshold.
  • Falls below: Alert fires if the incoming value falls below the threshold.

Threshold value (the threshold)

The value of the condition to measure that determines when an alert fires.

Threshold (for a duration of)

The time window during which the trigger condition must be met for the average of measurements coming in. For example, if you only want to be notified if disk usage is over 95% for at least 10 minutes, set to 10. The maximum allowed value is 60 minutes.
