When happen when the above condition met or true. When all conditions are true then alarm will trigger. Mean if anyone will be true, alarm triggerĪll: Similarly all condition work like “AND” case. Click “Next”Īny: it works like “ OR” operation between different defined condition. In Next page you will define you condition and his threshold level.

Based on specific event occurring on the object.įor sake of demonstration, I am going to create two alarms at vCenter level one from each condition.īased on the conditions and states of the objectĮxample 1: Create an alarm for datastore which will tell us and email when datastore will overcommit.Based on the conditions and states of the object.

There are two types of alarms available when you will choose to can create a new one. You can create your own custom alarm on various object levels in the vCenter inventory such as (vCenter, datacenter, cluster, individual object level) You can check the default datastore alarms which come with vCenterįrom WebClient-> datastore->Click on vCenter -> Manage-> Alarm definition -> Search “datastore”Īll the datastore related alarms are filtered as shown below You can adjust the existing alarm configuration or create the new one.
