Because super metric formulas can be complex, plan your super metric before you use the vRealize Operations Manager user interface to create it. The key to creating a super metric that alerts you to the expected behavior of your objects is knowing your own enterprise and your data.

1

Determine the objects that are involved in the behavior to track.

When you define the metrics to use, you can select either specific objects or object types. For example, you can select the specific objects VM001 and VM002, or you can select the object type Virtual Machine.

2

Determine the metrics to include in the super metric.

If you are tracking the transfer of packets along a network, the metrics are packets in and packets out because you are interested in the ratio of those metrics. In another common use of super metrics, the metrics might be the average CPU usage or average memory usage of the object type that you select.

3

Decide how to combine or compare the metrics.

For example, to find the ratio of packets in to packets out, you must divide the two metrics. If you are tracking CPU usage for an object type, you might want to determine the average use, or you might want to determine what the highest or lowest use is for any object of that type. In more complex scenarios, you might need a formula that uses constants or trigonometric functions.

4

Decide where to assign the super metric.

You define the objects to track in the super metric, then assign the super metric to the object type that contains the objects being tracked. To monitor all the objects in a group, enable the super metric in the policy, and apply the policy to the object group.
