Hi, I have been looking into enabling inactive data reporting for volumes to determine unused/inactive data in the volumes, but I am wondering if there are any other ways to determine the same.
I know one can always look at the AIQUM for IOPS history, but are there any other ways to achieve this ? And are there any performance considerations for using the Inactive data reporting feature ?

There is a "zombie report" in AIQUM that reports on volumes that are not in use. We have used that successfully at my customer.
I think the best way is to look at Max IOPs over the last month (or more if you're really paranoid) to make sure it has been 0 through month-ends, etc. Unfortunatley, that is not available in AIQUM. It may be available in Cloud Insights, but I haven't played around with that yet to know for sure.

Hi @bitter fable , so would Inactive Data Reporting feature not be effective here ? and do we only have to rely on AIQUM if we don't have Cloud Insights ?

You may be able to use Grafana as well. Usually, volumes with no IOPS are what you are looking for.

yes, Harvest is adding this feature https://github.com/NetApp/harvest/issues/3745 We'll update here once the feature is available
tough chasm
the next version of Harvest (25.11) to be released in the next week or two will include panels on hot and cold data as shown below. If you want to try this feature sooner, you can grab a nightly build. Let us know what you think

Just upgraded to harvest 25.11
Was wondering if I should see the panels added or do I need to preform more actions to add these panels as I currently dont see them on grafana.

hi @split sierra how did you install Harvest?
split sierra
System is already installed and running i just upgraded the system through the ui and seemed to have gone smoothley
tough chasm
I mean did you install Harvest natively, deb, rpm, nabox, container, something else?
split sierra
Nabox
tough chasm
thanks - try deleting all the dashboards from nabox - it will recreate them and hopefully you will see the new row in the volume dashboard
split sierra
Thorugh the grafana ui?
split sierra
Okay will get on it it seems the system has alert rules im new to this environment so I will check everything with my team tommorow and will let you know it it worked
Thanks for the help if it doesnt work I will reach out tommorow 🙏🙏
tough chasm
thanks, please do!
split sierra
Okay it shows the panels but says "no data" what could be the issue?

Are you using tiering?
split sierra
No I.was under the impression that this panels is suppose to track metrics about use of data in volumes to determine what is called/dead data.
Is configuring cloud tiering a must?
tough chasm
@split sierra can you grab a support bundle from nabox and upload to https://upload.nabox.org/wyxy-dima-ryqe
The panel mentions that Harvest only detect cold data for volumes whose tiering policy is not set to none. https://github.com/NetApp/harvest/wiki/FAQ#cold-data-detection-detail Check that you have volumes with a tiering policy other than none

In the past, I've used AIQUM and System Manager to identify unused volumes. In AIQUM, select Workload Analysis and then All Workloads. Select Filter and apply the following filters.
Once you have this list of volumes, you can then use System Manager to investigate each volume for last access details.
Storage --> Volumes --> File System --> Explorer
Ensure analytics is on and check last accessed times at the bottom of the page.

@tough chasm Isn't there a way to find cold data for a volume without any tiering, the main objective is for customers (who do not have proper documentation) to identify unused volumes which can be deleted so that space is reclaimed.
