Have you ever wanted to monitor the percentage of something, but been stuck with just the raw measurements? This is where vRealize Operations super metrics come into play. Super metrics are a mathematical formula in vRealize Operations which contain one or more numerical values. They can be used to calculate averages, percentages, sums, min and max, among others. In this blog, we’ll take a look at how we can create a percentage value using a super metric.
For this example, we have an Oracle DB tablespace resource from the Blue Medora Management Pack for Oracle DBs. The metrics provided show the allocated tablespace as well as the free space.

The first step to create a super metric is to create the super metric formula. To accomplish this you will:

Figure 4: Creating the super metric formula
Now that we have a super metric, we need to associate it with an object, so that the metric is tracked alongside other metrics for that object.

The last step is to enable the creation this Super Metric in our policy. Find the policy which your Oracle Databases are in (often times this will be the default policy). Then, we’ll enable the super metric by doing the following:

And there you have it! Creating a percentage super metric with vRealize Operations can be quite simple, and transform how you’re monitoring. For more information on super metrics, check out some of our other recent blog posts:
