Missing metric data after Harvest upgrade

[hazy sky]

After upgrading Harvest in NABOX, I'm no longer receiving data for volume_space_logical_available. Where do I begin to troubleshoot?

[proud sail]

Double check the roles required by harvest, they change over time

[final plover]

@hazy sky Could you share your ONTAP version? Also, do you see any data returned for this field when you run the query below?

volume show -fields logical-available

[hazy sky]

Roles were rechecked after the upgrade

[hazy sky]

9.12.1P10
Yes, I get returned data when running the command.

[final plover]

Okay, Could you confirm if you are using Rest or Zapi collector?

or you can share output of below command here https://netapp.github.io/harvest/24.05/help/config-collection/#nabox

dc exec -w /conf nabox-harvest2 /netapp-harvest/bin/harvest doctor --print

Thanks. We have fixed this in 24.05 (https://github.com/NetApp/harvest/pull/2904/files). Could you upgrade to this version?
https://github.com/NetApp/harvest/releases/tag/v24.05.1

[hazy sky]

Upgrade complete. How long do I have to wait for data to populate?

[final plover]

Not more than 5 mins

[hazy sky]

It's been longer than 5 mins and still no data.

[final plover]

Do you see other volume metrics like volume_space_logical_used for this Cluster?

[hazy sky]

Yes, I do.

[final plover]

If you query below endpoint
https://CLUSTER_IP/api/private/cli/volume?fields=logical-available
Do you get this field?
Also what is the output of below command in nabox?

dc exec nabox-harvest2 grep -r 'logical-available' /conf

[hazy sky]

Yes, the query produces the field.

[final plover]

Are there any errors in below command

dc logs nabox-harvest2 2>&1 | grep -w 'Rest:Volume'

[hazy sky]

No errors in the result. All results are "INF".

Just for reference, this was working prior to the Harvest upgrade.

[final plover]

Okay, with which version of Harvest did it work?

[hazy sky]

I don't recall exactly, but I think it was a 23.x release.

[final plover]

Thanks. We ll check on our end.

Thanks @hazy sky for raising this issue. With your help, we found the problem and fixed in https://github.com/NetApp/harvest/pull/2943
We can explain how to edit the template locally or you can install a new nightly build once that build passes CI. Let us know which you prefer

[hazy sky]

Please provide instruction to edit the template locally.

[final plover]

1. SSH as root to nabox:

2. Change the directory to /opt/harvest2-conf/conf/rest/9.12.0:

    ```sh
   

   cd /opt/harvest2-conf/conf/rest/9.12.0

3. Open the volume.yaml file with vi editor:

     ```sh
   

   vi volume.yaml

4. At line 33, Change the string logical-available to logical_available.

5. Restart nabox:

     ```sh
   

   dc restart

You can also install nightly build which has this fix
https://github.com/NetApp/harvest/releases/tag/nightly

[hazy sky]

A few seconds after modifying the file, it's being overwritten and the change reverted.

[hollow hollow]

sorry about that Lorne, that's an nabox-ism. Can you grab nightly and use it? If you'd rather not, take a look at the instructions documented here and make similar changes for volume.yaml https://github.com/NetApp/harvest/wiki/Enabling-FlexGroup-Constituents#for-nabox-installation

The gist of which is create a custom_volume_fix.yaml file, copy the existing volume.yaml to custom_volume.yaml, make your edits to the custom_volume.yaml file, update custom_volume_fix.yaml to point to the new custom_volume.yaml and then dc restart

[hazy sky]

I installed the nightly build and can confirm I'm receiving metric data now.
