As an on-prem customer, can I fine-tune a health rule using AST?

No, AST is available for SaaS customers only.

Can I use AST to fine-tune a health rule that monitors any entity?

You can use AST to fine-tune health rules that monitor business transactions, service endpoints, or remote services only. You must set the health rule evaluation scope to 'average for all nodes' of the affected entity.

How is the metric data presented in the AST graph?

If you define a persistence threshold for a condition, the metric data is plotted directly on the AST graph. If you do not define a persistence threshold, a 'moving average' for the selected metric is plotted. For more information, see Why use 'moving average'?.

What is a moving average? How is it helpful?

Unless persistence thresholds are used, health rules compare the moving average of a metric to a threshold or a baseline. Thus, representing the moving average in the graph is appropriate. 

Can I define 'persistence threshold' for a heath rule if I plan to use AST?

Yes, you can define 'persistence threshold' for a health rule. However, you will not be able to use the moving average for the metric. For more information, see Moving Average.

How does AST help calibrate the sensitivity of the health rule?

Depending on the baseline configuration you define, AST presents a graphical view of the metric data for the given baseline configuration. The graphical view is instantly updated when you update any configuration. You can also view granular details by modifying the graphical view. The historical metric data presented in the graph helps you calibrate the sensitivity of the metric evaluation (thus the sensitivity of the health rule).

I am not able to see the AST graphical view, how can I get the graphical view?

The graphical view may not be displayed due to multiple reasons. Check if you have:

  • created the health rule for a business transaction, a service endpoint, or a remote service.
  • set the health rule evaluation scope to 'average of nodes'.

Can I use AST to configure 'Critical' and 'Warning' criteria?

Yes, you can use AST to configure conditions for both critical and warning criteria.

Will AST impact the evaluation of boolean expression for health rule conditions?

There is no change in the evaluation of boolean expressions for health rule conditions.

Can I use AST to edit an existing health rule?

Yes, you can use AST when editing an existing health rule.
