Edit the check count in each alert definition to override the global control for how
many times Ambari checks an alert before dispatching a notification with a unique value
specified per alert.
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 both globally and for
each alert. 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 by modifying the check count value
specifically for each alert.-
