Modify the global alert check count

Use Alerts > Actions > Manage Alert Settings to set a global control for how many times Ambari checks an alert before dispatching a notification.

If the alert state changes during a check, Ambari attempts to check the condition a number of times. That number is called the check count. You can set the value of check count. Alert check counts are not applicable to AGGREATE alert types. A state change for an AGGREGATE alert results in a notification dispatch. If your environment experiences transient issues resulting in false alerts, you can increase the check count. In this case, the alert state change is still recorded, but as a soft state change. If the alert condition is still triggered after the specified number of checks, the state change is considered a hard state change, and notifications dispatch. Generally, you should set the check count value globally for all alerts. You can override the global check count value for any alerts experiencing transient issues.
  1. In Ambari Web, browse to Alerts > Actions > Manage Alert Settings.
  2. In Check Count, edit the value, as necessary.
  3. Click Save.
Wait several seconds for changes made to the global alert check count to appear for individual alerts in Ambari Web.
