We are wanting to build a heatmap that shows the many different guest file systems usage %. We have built alerts based off of usage % with different thresholds, but building a heatmap has proven difficult. We have many SQL servers with upwards of 25 mountpoints that we would like to show in the heatmap.
And if a heatmap isn't the correct display choice, some suggestions would be great.
Your best bet would to create a View. When creating the view select the following for the wizard: List, Virtual machines, Guest File System > C: > Free Space Remaining (GB) ... then create a filter to display when it is less than 5GB for example. One thing to note is that Free Space Remaining for the C: Drive is no longer enabled by default. You will need to follow the instructions in the link below to enable the hidden metric. Once completed, repeat the process for D drive, E drive, etc.
The problem i have with heat maps is they can be a pain to configure and not very flexible.
I looked at creating a Metric Config so you could use an object list feeding into a scoreboard that uses the metric config but listing the drives (c: d: etc) is not a valid metric. I get "Failed to get attributeKeyId for = guestfilesystem:D:\\|percentage" the only valid ones that can be included in a config file in the first column below:
The only options i see you have are
1 The view in the above post
2 A heat map with a configuration for each mount point.
3 A scoreboard got each SQL server ( will have a scoreboard per SQL server.
2 & 3 are not ideal because if any new mount points are added the dashboard will need to be manually updated.
Thank you for the response, and it was helpful but we are after more of the guest file system usage % as we have disk of varying sizes so alerting that the free space on 1 C: drive with 5GB might not work on another.
We try to use usage % as a better metric and then use 85/90/95% for alerting. Funny thing is we get alerts for that, on all drives and mountpoints, but we cannot find away to get that information on a dashboard, list, or heatmap. The biggest reason is that we are trying to give our Cells access to this information so they can better support their servers and applications.
We are working with a VM engineer for vrops on some other issues, but I was going to present this quandary to him also.
If all you wanted is Usage % than that's even easier. Follow the same steps and expand C: and select Guest File System Usage (%) (See picture below). I was suggesting Free Space in GB because that gives me a more accurate picture of how much space i have left. 90% of a 1000GB drive basically means you have 100GB of space left, that to me doesn't indicate a problem, but it's up to you. Also the creating a View gives you the ability to add it to a report and to also to add it to a dashboard as well.
