Custom groups are a handy way of grouping objects, similar or dissimilar, into a set and using the group in a dashboard or view for easy access and quick troubleshooting. Groups can be:
- static – objects like vCenter Servers can be termed ‘static’ in vROps terms, it’s not like you create them every other day or you are setting up monitoring of a fairly static environment, such as a DMZ.
- dynamic – objects like VMs are quite dynamic like in a VDI environment especially when non-persistent desktops are in use.
- associated with adapters – you can only edit these groups from the adapter instance.
Basically, custom groups are a way to categorize objects together. Be careful with the policies you attach to/apply to custom groups as policies dictate how vROps calculates trends and generates recommendations.
To create a group:
- Go to the Environment tab, then to the Groups tab and click on the green plus to begin creating a group.
- Here’s a group called VDI group that I’m creating specifically for VDI clusters, here are its properties
The idea behind this group is this:
- I wanted a group that grouped specific VDI clusters that I could later use to show CPU utilization within the clusters.
- I used the VDI Policy which I customized to suit my needs.
- “Keep group membership up to date” – is very handy, you couldn’t do without it. Basically, new additions to clusters get added automatically.
- Next, I chose the Object Type as the Cluster Compute Resource in Define membership criteria.
- In Objects to always include, I chose the two clusters I want to create the group for. You need to double-click the check boxes next to the clusters.
- You need to ensure you click the tiny down arrow next to the Add button which reveals something very important – selected objects and descendants. This will includes the clusters, the hosts, the VMs, the datastores – basically every object within a cluster. Click on “Selected objects and descendants” and then click on Add. If you miss this step, only the cluster object will be included in the group resulting in skewed/incorrect data wherever you use this group.
- Sit back and let it add every object to the right (where it says “Objects to always include (0)”. This may take a while depending on the size of your clusters. In my case, it took about 15 minutes.
- Click Ok to finish creating the group.
I’ve now created a group that I can use within Dashboards and custom Views. Next post will discuss using this group in Dashboards and Views.
