Hi all,
I don't know we can already do it but I however ask 🙂
Harvest system can get the data abouts the following ONTAP command ?

sis stat -vserver * -volume *

Thank you,
Best Regards,
Francesco

I explain better , sorry. I need to have data for fields num-compress-attempts,num-compress-fail.
Do you know if we can get also these data ?

@peak mica Could you share CLI for this? I have found this information
https://CLUSTER_IP/api/private/cli/volume/efficiency/stat?fields=num-compressed-inline

volume efficiency stat -instance

#

I see these at diagnostic level

https://cluster_ip/api/private/cli/volume/efficiency/stat?fields=num-compress-attempts,num-compress-fail&privilege_level=diagnostic

#

Does this work for you?

peak mica Apr 17, 2023, 10:20 AM

#

yes!! Thank you!
But this API path could be called by harvest system to graph these kind of data ?

cobalt hinge Apr 17, 2023, 10:20 AM

#

Yes It is possible

#

Could you open a feature request for this on github issues

peak mica Apr 17, 2023, 10:21 AM

#

Thank you again Rahul! Amazing!

I'm here again. I have a read-only user that can't read data from diagnostic level. Can I extend the visibility of read-only user also on diagnostic perimeter ?

#

I have a user with role which has rest access for api that works fine for diagnostic . Could you share output of below command

security login role show -role ROLENAME

@peak mica A pull request has been created for the counters, and you can find it at this link: https://github.com/NetApp/harvest/pull/1958/files.

Regarding the inclusion of these counters in the volume dashboard, could you please let me know if you would like them to be displayed as a time-series panel or just current data?

Hi guys, sorry to bother, I think @peak mica and me we made a mistake asking for that panels in volume dashboard. Which is the right place to explain? Here or on github discussion?

cobalt hinge May 23, 2023, 9:49 AM

@warm citrus Either way is fine. Discord is perhaps faster.

We found that maybe sis panels (num compress attempts, num compress fail) will remain unpopulated with Ontap version 9.8 and later
https://kb.netapp.com/onprem/ontap/dm/Efficiency/No_compression_savings_in_ONTAP_9.8P1_or_later

Since that was a specific request maybe we can address efficiency data with custom dashboards, so feel free to remove that panel in future releases...

Anyway discussion open 😉

NetApp Knowledge Base

No compression savings in ONTAP 9.8P1 or later

Thanks we ll take a look

We've been able to compare data between clusters "9.8 native" and some other that have been upgraded with earlier version. Counter num-compress-attempts is ever 0 for volumes on a cluster that is factory configured with 9.8 and later.

I have opened an issue for the same https://github.com/NetApp/harvest/issues/2106

@warm citrus

We have gone through the KB article https://kb.netapp.com/onprem/ontap/dm/Efficiency/No_compression_(reporting_0)savings_in_ONTAP_9.8_or_later_at_the_volume_level and compared couple of 9.12+ clusters for this counters (num_compress_attempts, num_compress_fail).

Our newly added Volume Sis Stat panels required ONTAP 9.12+ and the APIs are only available via REST for collecting above mentioned counters. we have validated, this panel would showing appropriate data for 9.12+ clusters.

We have decided to retain Volume Sis Stat panel as-is, as it's working as design.
