Part 7: vCenter Operations Custom UI – Customizing the Advanced Health Tree Widget
Part 6 of the vCenter Operations Manager – Custom UI Series will go into depth for configuring the Advanced Health Tree widget. The Advanced Health Tree widget displays a section of resources hierarchy for any resources that you select. This includes both parent and child resources for the object selected. Additionally, the tree can display information regarding the grandchildren and their health. My preferred method of using this widget is to use groups, specifically nested groups for an easy breakout of a particular environment. Using the example found in my previous post: vCenter Operations Manager – Creating Nested Groups we can create a widget to quickly display the entire SharePoint environment, from top-level group down to the servers that make up each tier.
A few examples of what the Advanced Health Tree widget looks like:
1) Select the dashboard, or create a new dashboard, where you’d like to display the Advanced Health Tree widget. Click the Edit button next to Dashboard Tools.
2) Drag and drop the widget from the left column over the right column and click OK.
3) You should now have a blank, unconfigured widget on the dashboard. To edit the widget, click the Gear icon at the top right of the widget.
4) You should now be in the ” Edit ‘Advanced Health Tree’ widget” window as seen below. As with most widgets, you’ll want to turn ON the Self Provider option, select the Refresh Widget Content option to automatically refresh the content on the screen and choose the interval to refresh the data in the box below.
Now to choose what data the widget is to display: First, select the desired resource in the Resource Selection box in the middle. This will be the resource the becomes the focal point of the widget. In our example, we’re going to select the Environment group named Sharepoint – Dev. Click ok to finish the configuration, which will show you everything regarding the selected resource.
If you’d like to filter some things in/out, use the tags selection at the bottom. For example, if you only want to display running VMs, select the tag under VM Entity Status called Powered On. If you only want to display some of the application tiers but not others, select only the ones to display.
Below you can see we’ve selected the Sharepoint – Dev resource (which is a previously defined group) and selected the tags for three tiers nested under this group (these are also groups that were previous defined in this article)
**The widget below is a direct result of the configuration shown above.**
Last but not least, you should play around with what selections make sense for you. For example, selecting the Application Tier group in the configuration above would display the tree like below. Now the Application Tier is the focal point with the parent (SharePoint – Dev) shown above and it’s children (VMs) are shown below it.
