Hi all, I‘ve just saw that since we upgraded to the new harvest 23.11 version, the power consumption of the nodes is missing. I checked the documentation page regarding to the permissions and from my point of view it looks fine. We have a local user called nabox with the default readonly role. Ontapi and http are also defined.
After the downgrade the data is back

@vale wasp Can you email us Harvest logs for this poller to ng-harvest-files@netapp.com . https://netapp.github.io/harvest/23.11/help/log-collection/
vale wasp
Hi @regal birch mail is send
regal birch
Thanks Received. From screenshot, I see that Node power is being reported in 23.11 but lesser than 23.08. This is expected.
https://netapp.github.io/harvest/23.11/resources/power-algorithm/
I also don't see any relevant errors in logs.
vale wasp
hmm interesting. Let me check another environment
vale wasp
but what this looks wired, after upgrading there are no more metrics in the dashboard for an A250
regal birch
Okay is this some other environment? From email screenshot, I do see node power reported. If yes, can you share logs from this environment
vale wasp
log is on the way

I see the error. You need to provide Rest permissions for the relevant user for these clusters.
As mentioned here

strage. the user which we use have the readonly role, which have access to rest
regal birch
okay. Can you try running below for that cluster? Replace USER,PASS,CLUSTER_IP as applicable.
curl -s -k -u USER:PASS 'https://CLUSTER_IP/api/cluster?return_records=true&fields=*'
that worked. Ok found the issue, after enabling REST I need to restart the poller in the NABox 🙂
regal birch
Great! Power Collector failed during startup, hence, even after granting permissions, it didn't retry. It makes sense that a restart was needed.
vale wasp
yes I can confrim after addind the http application and restarting the nabox or poller it works again, thank you for your help 🌻

I have also added the same in docs https://github.com/NetApp/harvest/pull/2572/files
dapper swift
the same problem with harvest 24.05.1. REST is enabled, checked that with:
vserver services web access show -role harvest2-role -name ontapi
vserver services web access show -role harvest2-role -name rest
vserver services web access show -role harvest2-role -name docs-api
did anyone see the node power in nabox 4.0.0?

Isn't it a known issue for the A250?
Harvest does not calculate power metrics for AFF A250 systems. This data is not available from ONTAP via ZAPI or REST. See ONTAP bug 1511476 for more details
dapper swift
my test system is a A300 and no one of my AFF systems show the node power. @limpid wraith , did you see node power in nabox 4 with harvest 24.05.1?
regal birch
For me, I am getting power metrics for AFF300. @dapper swift We'll know more from logs.

this is the command - right?: nabox4 ~ $ dc logs havrest > havrest.txt
sent them again - thank you.

@dapper swift Based on harvest logs, this is a REST permission issue. There are a few endpoints which are succeeding while others are failing. We updated the documentation for REST permissions some time back, which is available at https://netapp.github.io/harvest/24.05/prepare-cdot-clusters/#create-rest-role. Could you recreate the REST role as mentioned in the document, restart Harvest, and check if it is working?
dapper swift
@regal birch , thank you so much for your support - works now!
