I created a Custom Group in vRealize Operation Manager 6.1 and I'd like to see a Trend graph of all VMs in this group under Details > Views, however there are only List and Distribution 'Types'. If I select a single VM, there are Trend report options. Is it possible to get these Trend Type of graphs created for a group of VMs? It would be nice to see them all on one graph.
Nope - trend reports can only be run on one object at a time. If you want a line graph with multiple lines in a graph representing different objects in a REPORT, your only chance would be to create a custom dashboard and import that in to a report. However, YMMV and you'll need to statically configure the dashboard widgets (all would be self providers, no interactions).
