SLA Performance

This alert notifies you that a potential SLA performance violation occurred.

The SLA performance test requests the SLA test object via the edge servers and directly from your origin server and compares the load times with previous data. When the target performance value reaches a set threshold, it fires this alert. It may indicate SLA violations which can be caused by spurious measurements, misbehaving agents, or other situations that do not constitute a valid SLA violation.

You can set this alert to monitor one SLA test.
