A feature that VMware VI3 offers and that is definitely worth the ten minutes it takes to configure are the alarms. VMware VI3 gives us the opportunity to receive alarms (via a script) or be notified (by mail, SNMP) for changes in certain parameters of our VM.
The alarms indicate the status of objects, which can be: folders, datacenters, clusters, resource pools, and hosts and VMs. In fact, on the left side of the VMware Virtual Center, you can see these objects and their hierarchy.

In this way, setting a couple of alarms is enough for all of my VMs. If one particular VM or parameter that is not specifically monitored with the above-mentioned alarms interests me, I can set another alarm for it. This, however, does not happen often.
There are only two alarms that I would like to set for Hosts & Clusters: one type is an Alarm Host and the other is an Alarm VM. This will allow me to know what is happening to the Hosts and VMs I have in my virtual infrastructure.… Read More
