The main motivation to use alert queries is a modeling solution based on data contained in the alert itself, as an alternative to using either discovered, application, or technical services.

Create an alert query to combine similar alerts that meet the specific criteria.

   주:

   In the Filter field:

   • When defining an alert query filter, include only fields that appear in the Alert Histories [em_alert_history] table. Impact calculation is based on Alert History data and fields such as Overall Event Count, Priority, and Priority group are not copied to the Alert Histories [em_alert_history] table.
   • Do not specify a dynamic time condition. For example, in the filter, do not specify Created condition of Last 45 minutes because impact calculation is triggered by a change of alert or alert query. However, for the dynamic time condition, none of these conditions have changed.
   • Some filters may slow down impact calculation. To solve this problem, adjust your alert query by adding an appropriate index, as described in Index suggestions for slow queries.
4. Select Update.
