Why are some alert variables available and some aren't (Virtual Machine Alerts)

sethrandall

I have created an event for old VM snapshots. I would like the notification to list in which DataCenter and Cluster the VM is located.

I am seeing and inconsistency with which entities are available.

I can use ${N=SwisEntity;M=Host.Cluster.Name} to get the Cluster Name, but ${N=SwisEntity;M=Host.DataCenter.Name} doesn't provide the Data Center name.

Example:
Alert ${N=Alerting;M=AlertName} on ${N=SwisEntity;M=Name} in ${N=SwisEntity;M=Host.DataCenter.Name} ${N=SwisEntity;M=Host.Cluster.Name}.

Produces
Alert VMware - Alert on old snapshots on VM001 in ${N=SwisEntity;M=Host.DataCenter.Name} VM Cluster 1.

How do I get the DataCenter name?

I'v posted a few times but some variables will not be available in all contexts.  Using the SWIS/SWQL studio as a frame of reference, the deeper tables can link up to the higher ones to see most of their variables, but none/fewer will be available from a higher level table to lower level one.  

It's super difficult to find me own posts on the forum but ill try to find a link to the feature request I put out about this.
