Question 34 - 5V0-35.21 discussion

A super metric is a mathematical formula that contains one or more metrics or properties for one or more objects.It can be used to create custom metrics that are specific to your environment and can help you gain deeper insights into the performance and health of your infrastructure1.Super metrics can be applied to any object type that contains the objects or metrics involved in the formula2.

Option A is a valid super metric, as it calculates the average CPU usage of VMs within a Datacenter, which is an object type that contains VMs as child objects.The formula for this super metric could be something likeavg(${this, metric=cpu|usage_average, depth=1}), which means the average of the CPU usage average metric for all the child objects of the current object3.

Option D is also a valid super metric, as it counts the number of Non-Windows VMs in a vSphere cluster, which is an object type that contains VMs as child objects.The formula for this super metric could be something likecount(${this, metric=guestfilesystem|osType, depth=1, where=not contains windows}), which means the count of the guest OS type metric for all the child objects of the current object, where the value does not contain the word windows3.

Option B is not a valid super metric, as it involves the difference of CPU utilization for each VM between two defined time stamps, which is not a metric or property that can be used in a super metric formula.Super metrics can only use metrics or properties that are collected by vRealize Operations, not arbitrary time stamps2.

Option C is not a valid super metric, as it involves string operators that are valid to be used with mathematical calculations in a function, which is not a metric or property that can be used in a super metric formula.Super metrics can only use numerical values, not string values, in mathematical calculations2.

Option E is not a valid super metric, as it involves the average SCSI count with disk size of VMs within an ESXi host, which is not a metric or property that can be used in a super metric formula.Super metrics can only use metrics or properties that are available for the object type that the super metric is assigned to, and the SCSI count and disk size are not available for the ESXi host object type2.
