Additional Considerations
-
Your application status is based on health rules for the current time range. If you disable old health rule policies or enable new ones, you might see errors in red in your application status, even if there are no current critical events based on the new policies. To verify that your new or disabled health rule policies have taken effect, change the time range in your dashboard to a smaller, more recent time frame.
- When you are configuring health rules for business transactions with baseline selected in the configured condition with a very fast average response time (ART) such as 25 ms, using standard deviation as a criterion can cause the health rule to be violated too frequently. The health rule may violate too frequently because a tiny increase in response time can represent multiple standard deviations. In this case, consider adding a second condition that sets a minimum ART as a threshold. For example, if you do not want to be notified unless ART is over 50 ms, you could set your threshold as ART > 2 Standard Deviations and ART > 50 ms.
- Similarly, when configuring health rules for calls-per-minute (CPM) metrics with baseline selected in the configured condition, the health rule may never be violated if the condition is using standard deviations, and the resulting value is below zero. In this case, consider adding a second condition that checks for a zero value, such as CPM < 2 Standard Deviations and CPM < 1.
