I came across an interesting query on Reddit regarding vRealize Operations Manager (vROPs), summarised the query;
“Can I have a vROPs report/dashboard which shows me the storage usage by VMs over the past 3 days”
The short answer is yes, and I produced the following dashboard, views and report and uploaded to code.vmware.com for the post author to use.
My dashboard has two elements to keep things simple;
- A sparkline widget of VM’s storage used, the time frame show can be controlled in the dashboard view in the top-right hand corner
- A list view of the VMs storage used covering a few metrics
- Current Disk used
- Disk Used (3 days ago)
- Change of disk used (in GB)
- Change of disk used (in %)
So, let’s look at how I created this.
Creating a Sparkline widget in the Dashboard
Create your dashboard, which will show you a blank canvas. Set the Dashboard name.
- Drag the Sparkline Chart widget onto the canvas and resize as needed, you’ll see this option appear by hovering over the edge of the widget.
- Click the pencil icon to edit the widget settings.
Configure the Widget configuration. The most important options here are;
- Self Provider – On
- Show Object Name – On
- Column Sequence – Label First
This means the widget will provide its own metric data to be displayed. It is not linked to other objects on the dashboard, as we are keeping this as a simple view. Continue reading How to build vROPs dashboard for tracking VM Growth over X days
My customer asked me how to display the VLAN ID for a virtual machine in vROPs.
The short answer is, due to the VLAN ID only being available from the Distributed switch adapter, its not simple to display this in a single list view.
So after some thinking around this, I came up with the following simple dashboard which was edited from the default “Distributed Switch Configuration” dashboard.
The dashboard is simple, and shows a selectable list of port groups, which then will refresh the virtual machine list, so you can see which virtual machines are attached to that port group.

A customer of mine queried the details of a metric available in vROPs “IsGreenForPlacement”
You can find this by selecting a cluster in vROPs, go to All Metrics, and just search placement.
And here is a screenshot of the Metric in a sparkline.
The customer uses this metric to give a signal (Green/Red Button on a vROPs Dashboard) if a vSphere cluster can be used for on-going deployments.
Unfortunately there’s not much documented information publicly. And we ran into an issue where the metric stayed positive (yes you can deploy), but the Storage datastore had run out of space. So I went off to dig out what this metric actually does.
IsGreenForPlacement – details
After speaking to the internal teams on vROPs I found the answer;
“Regarding IsGreenForPlacement metric, only CPU and Memory participates on calculation of this metric, by default if CPU and MEM workload is less than 80% it is green.”
So storage is not taken into account.
Creating a Dashboard
This one will be really simple. Continue reading vROPs – What is the “IsGreenForPlacement” Metric + Dashboard
I had an interesting question from a customer recently;
Can we track the adoption/upgrades of VMware tools to the latest version in a vROPs dashboard
At first, I thought sure this is easy. But then looking at the various different default options, nothing would give me a graph which shows the increasing uptake or upgrades of VMware Tools to the last version.
I consulted internally, and between myself and my customer we came up with the following solution. Which was quite simple once we thought it out.
- Create a custom group based on the information you want to capture
In the below example, I’ve done this to target VMs with VMware Tools 10.3.10, you could leave it as “10.3” to target any 10.3.X release. Continue reading Using vROPs to track adoption – Such as VMware Tools upgrades
