vi /var/lib/ambari-server/resources/host_scripts/alert_disk_space.py

# defaults in case no script parameters are passed

MIN_FREE_SPACE_DEFAULT = 5000000000L #5GB

PERCENT_USED_WARNING_DEFAULT = 50

PERCENT_USED_CRITICAL_DEFAULT = 80

You can change the above parameter to avoid alerting at 80% threshold reached in case it needs to be aletered to 85 or 90

    @Neeraj Sabharwal

    As per Ambari REST API docs https://github.com/apache/ambari/blob/trunk/ambari-server/docs/api/v1/alert-definitions.md

    the definitions can be updated

    Is it possible to use REST API to update these thresholds ?

    If not, then once the cluster has been deployed should these properties be updated in /var/lib/ambari-server/resources/host_scripts/alert_disk_space.py and then ambari server restarted to push this update to all the agents ?

    I couldn't find a way to update these thresholds in Ambari UI

    In addition don't forget to re-start Amabri-server after making above mentioned changes.
