Auto-Close Options
The Windows agent allows the auto-closure of alerts when the criteria condition that caused the alert no longer exists.
When creating a rule, within the Advanced tab of the rule criteria, an Auto-Close Options section is available.
The Auto-Close Enterprise Console Alerts parameter within the Auto-Close Options section of the Rule Criteria - Advanced tab defines whether Enterprise Console alerts for the rule are to be auto-closed and if there is any grace period before they are closed.
When the rule is checked, if the criteria selection would not currently result in an alert and there are previously raised outstanding alerts in existence, the existing alerts are closed after the specified Delay period if the criteria is still not triggering.
- A CPU rule has criteria to alert if the CPU % Processor Time is above 75%.
- It also has Auto-Close specified to Auto-Close Enterprise Console Alerts with a Delay period of 5 minutes
The rule criteria is checked and triggers as the CPU is above 75%. An alert is sent to the Enterprise Console. At the next check interval, including any time for which the rule is suspended, the rule criteria is checked again and the CPU is below the required threshold. As the criteria has auto-close specified, the outstanding alert is tagged to be automatically closed five minutes later.
The rule criteria continues to be checked and if the CPU does not cause any further triggers, the existing alert is closed at the tagged auto-close time.
