Evaluate multiple condition blocks
You can use complex conditions to evaluate multiple condition blocks, or sections, independently. For example, you may want to create an alert when an application is down and when your fail-over server is active for more than an hour.
- Enable complex conditions.
- Click Add Section.
- Select And then after from the drop-down menu between the two condition sections.
- Choose how long to wait before evaluating the next section.
- Create the next condition block.
How condition blocks are evaluated
The condition blocks are evaluated at the same time. If they are all true based on the conditions, the alert triggers. For example, condition A, B, and C must be true in order for the alert to trigger.
(Condition A) & (Condition B) & (Condition C)
Condition blocks are evaluated using variations of AND, so the trigger condition in each section must be met.
A condition block can be evaluated at a different time than other condition blocks. For example, if you want to be alerted if the backup system is active for more than an hour, you can choose to wait an hour after the primary condition block, where the application going down is the trigger condition, before evaluating whether the backup system is still active.
