Awesome! Is it possible to see data from my eSeries behind StorageGRID SG6060 in the new eSeries Dashboard? How do I enable it?

https://netapp.github.io/harvest/26.02/prepare-eseries/
https://netapp.github.io/harvest/26.02/configure-eseries/

You would configure ESeries just like ONTAP in harvest configuration. Just collector names are different. See example below

Pollers:
  eseries-array:
    datacenter: DC-01
    addr: 10.0.1.100           # E-Series array management address
    use_insecure_tls: true
    username: monitor                   # Array user with Monitor role
    password: enterpass               # Or use credential_script
    collectors:
      - Eseries
      - EseriesPerf
    exporters:
      - prometheus

Yes, works now. Fsntastic Work Guys, awesome!

crisp jay Feb 17, 2026, 12:31 PM

#

Great!!

#

Please let us know feedback or any additional request for ESeries via https://github.com/NetApp/harvest/issues/1357

tender peak Feb 17, 2026, 12:35 PM

#

Okay.... I have >30 of them, need to add them all and tuen I'll See what happens

#

Can I See Performance Data of Cache SSDs Here?

crisp jay Feb 17, 2026, 12:43 PM

#

There is cache hit ops at controller and array level
And cache hit ratio at volume level

#

Are you looking for this or drives performance data?

#

Currently available E-Series metrics in Harvest are documented at: https://netapp.github.io/harvest/26.02/eseries-metrics/

tender peak Feb 17, 2026, 1:33 PM

#

We've Had Performance issues with rangedb 0, so I hoped to See Performance metrics for those dedicated Cache SSDs.
Should we move this discussion to a new Thread?

crisp jay Feb 17, 2026, 1:36 PM

#

Sure. Yes, a new thread works. See if above screenshots for volume level cache help.

After upgrading to 26.02 volume metrics are not working

celest hollow Feb 22, 2026, 4:20 PM

#

I am not able to under stand what exactly changed for the new harvest 26.02 I am using zapi role. Should I need to create rest based roles to see the volume performance metrics or can you provide a clear doc how I can fix the issue

crisp jay Feb 23, 2026, 4:24 AM

#

@celest hollow You may be hitting a permission issue because, starting in 25.11, volume performance metrics use the KeyPerf collector. More details here: https://github.com/NetApp/harvest/discussions/3900

You need to provide read permissions for api/storage/volumes endpoint.

security login create -user-or-group-name netapp-harvest -application http -role harvest-rest-role -authentication-method password

Error: command failed: duplicate entry
netapp-harvest http password netapp-harvest-role no none
netapp-harvest ontapi password netapp-harvest-role no none

#

I have created zapi rules under Netapp-harvest-role

#

Now I have created a another role for netap-rest-role for getting the volume metrics

#

But do I need to update the https login to the use the new role ?

flat horizon Feb 24, 2026, 5:41 PM

#

hi @celest hollow if you had an earlier version of Harvest that worked with Zapi. You should only need to add the commands listed here https://netapp.github.io/harvest/nightly/prepare-cdot-clusters/#ontap-910-volume-performance-metrics

celest hollow Feb 24, 2026, 6:12 PM

#

I have used below two Commands and greeting above error

security login rest-role create -role harvest-rest-role -access readonly -api /api/storage/volumes
security login create -user-or-group-name harvest2 -application http -role harvest-rest-role -authentication

flat horizon Feb 24, 2026, 6:18 PM

#

The duplicate entry message means you already have those permissions. Can you share your poller logs for the poller that is not collecting volume metrics at https://upload.nabox.org/taco-cowe-xizi

celest hollow Feb 25, 2026, 8:53 AM

#

Done

#

Done

#

Uploaded the log

jaunty minnow Feb 25, 2026, 10:09 AM

#

@celest hollow Thanks for the logs.
I have checked the logs, There are Rest:Volume collector is running for all poller and it succeed and no errors there. apart from that, There are no entry for any kind of volume perf collector running and no errors or warn logged. There are no role related errors also been found. We found there are few customization for volume, but those logs are also rolled out.

VolumeAnalytics related error when volume is offline, but this is not much concern and it's genuine, this doesn't affect volume perf collection any way.

Looks like, logs might be rolled over as there are no poller start after the upgrade happened.

Could you please restart the pollers and run for 5 mins and then collect the logs and share us the logs again at the same location to troubleshoot further.

Thanks for new logs @celest hollow
As per the logs, it's found that restperf customization is not proper. and file custom_volume.yaml would not be found there which would cause skipping perf collection for volume object.

As per the custom.yaml file in restperf folder, it's expecting custom file should be named as custom_volume.yaml, but you have custom file named as custom.yaml in your etc/nabox/harvest/user/restperf/9.12.0 location. and matching template is not available.

Suggestion:
Can you try removing this file by rm -rf etc/nabox/harvest/user/restperf/custom.yaml and restart Harvest which should show your volume perf metrics.
I see that you have tried to enable volume top clients in volume perf template, Could you upgrade to 26.02 latest release and apply this customization based on this discussion: https://github.com/NetApp/harvest/discussions/3904

Is there a certain eSeries Version needed for this to Work?

#

We are in santricity 11.70.5P1

crisp jay Apr 13, 2026, 7:29 AM

#

As per
https://docs.netapp.com/us-en/e-series-santricity-118/sm-storage/how-ssd-cache-works.html#ssd-cache-versus-primary-cache

It seems, it is available since 11.8

#

Let me check the version we tested

crisp jay Apr 13, 2026, 7:37 AM

#

tender peak We are in santricity 11.70.5P1

Do you have ssd cache set up in this version? 404 shows that this API doesn't exist in 11.7

tender peak Apr 13, 2026, 7:38 AM

#

Yes, harvest nightly 2026-04-13

#

I will probably Update to santricity 11.80.1R4 later - seems to Work with StorageGRID 11.9.0.11 as far as I can tell

crisp jay Apr 13, 2026, 7:50 AM

#

Yeah I am trying to find when endpoint storage-systems/1/ssd-caches was introduced

#

I will check with the eseries team regarding the API and determine from which version it is available, since Harvest relies on this API for the SSD cache metric and can only support versions where the API is present.

tender peak Apr 13, 2026, 8:29 AM

#

My SAM says I should Upgrade to 11.90R3, so will fix this later today

tender peak Apr 13, 2026, 10:30 AM

#

Update done, but I still can't get SSD statistics. Harvest restart, Problem stays Like the Error I posted earlier

#

Do I need any licensed Features, Not Sure what is licensed in santricity anyway?

crisp jay Apr 13, 2026, 10:39 AM

#

Let's see what Eseries team says. I can see this API is available in
SANtricity OS software version
12.00R0

crisp jay Apr 13, 2026, 10:40 AM

#

tender peak Do I need any licensed Features, Not Sure what is licensed in santricity anyway?

I don't believe that's the case. From what I understand, flash-cache likely evolved into ssd-cache as indicated by the API specification. The API spec notes that the flash-cache API was deprecated starting with version 8.0, and we should now use the ssd-cache API.

#

tender peak Apr 13, 2026, 10:51 AM

#

crisp jay Apr 13, 2026, 10:53 AM

#

Yeah we are not using this API in Harvest.

#

Is it possible for you to upgrade to 12.00R0 version?

tender peak Apr 13, 2026, 10:57 AM

#

Nope, I think this requires StorageGRID 12 first

crisp jay Apr 13, 2026, 10:58 AM

#

Okay. We'll check with ESeries team for API for older versions. We are currently using below API for ssd-cache metrics
Capacity: storage-systems/{array_id}/ssd-caches
Performance: storage-systems/{array_id}/ssd-caches/{ssd_cache_id}/statistics

tender peak Apr 13, 2026, 2:27 PM

#

Updated to santricity 11.90R4 - still Not working

flat horizon Apr 13, 2026, 2:33 PM

#

thanks for the update @tender peak The E-series team have confirmed that the storage-systems/{array_id}/ssd-caches endpoints don't exist before SANtricity OS 12.00. We're checking to see if we can get similar metrics from the flash-cache endpoint. It looks like the flash-cache endpoint may only provide capacity information without SSD-cache performance stats. We've asked the E-series team for clarification.

crisp jay Apr 23, 2026, 10:40 AM

#

tender peak Updated to santricity 11.90R4 - still Not working

@tender peak There is a symbol API in ESeries for SSD cache to collect performance metrics, but it requires a new collector in Harvest since the current collector does not support this API format. We do not have plans to develop such a collector currently. At this time, SSD cache metrics will only be supported from version 12.00 onwards.

flat horizon Apr 23, 2026, 11:31 AM

#

If you need those metrics on an earlier version of santricity, please open an issue or chime in on the existing one https://github.com/NetApp/harvest/issues/1357

Does this version have updated Grafana dashboards that support Grafana version 12+. My Grafana is on 13.x so the older json does not play well.
