As covered earlier in the book, vCenter does not provide information at the Distributed Switch level. This makes monitoring difficult, as you cannot slice the data from the switch point of view. vRealize Operations addresses this by providing the necessary counters at the Distributed Switch level and its port groups.
The next screenshot shows that vRealize Operations has network as a first-class citizen. The structure shows a Distributed Switch called Site 1 Distributed Switch. vRealize Operations shows the objects associated with it, such as these:
Distributed port group
Distributed port group (NSX)
Uplinks
ESXi host
This screenshot shows the metrics for a Distributed Switch object:
As you can see, it has the usual network metrics you would expect. From the metric, you can also create a super metric. For example, you can create a super metric that tracks the maximum of MTU Mismatch, Unsupported...
