Hello, how do we get the latency, IOP, Throughput information to show up within the above mentioned report? Is the data collection not supported via REST?
#ONTAP:SVM Data Not Showing

@covert elbow It is supported. Can you share Harvest logs @ https://upload.nabox.org/pade-yity-kabi

@covert elbow I don’t see anything in the logs that indicates why the SVM dashboard is empty. If we focus on one panel in the SVM dashboard ,SVM average latency. Are you saying this panel is empty? If so, could you check whether there is any data for the metrics svm_vol_read_latency and svm_vol_write_latency in the time-series database? Do you see performance data in volume dashboard?
covert elbow
All of the panels mostly at the top for anything performance related just says “no data”.
gloomy shoal
How about volume dashboard? Does it have performance data in highlights section? If you run above metrics queries in time series db. Do they return anything?
covert elbow
volume dashboard I see the performance data.
The timing of this seems to have happened AFTER I ran out of space on my /data directory and expanded the drive and restarted machine.
But maybe that is nothing and just coincidence.
sour atlas
hi @covert elbow can you check in VictoriaMetrics UI for the metrics that Rahul asked about? svm_vol_read_latency and svm_vol_write_latency
covert elbow
WARNING: No match! This query hasn't selected any time series from database.
For both
Is that what you needed?
sour atlas
yes, that is unexpected
covert elbow
WARNING: No match! This query hasn't selected any time series from database. Either the requested metrics are missing in the database, or there is a typo in series selector.
sour atlas
ok so VM does not have the metric, that's why the dashboard is blank. Now, why doesn't VM have the metric. The poller should be exporting it so why isn't it. Let me check your templates more closely - we noticed that you have made several modifications to them so maybe something when awry there
covert elbow
Hmmm, I haven't made any changes to templates. I pretty much use this "as is"..
sour atlas
looks like you have a restperf custom.yaml for volume and since the missing metrics come form the volume perfomance collector it makes sense to focus there. Can you try disabling you custom.yaml, restarting the containers (dc down; dc up -d), and then checking if the metrics are available after 5 minutes or so?
covert elbow
Let me check that out now and get back soon.
There are a couple of locations but since I use REST I would assume it's this location - /etc/nabox/harvest/active/restperf: 9.12.0 custom.yaml
sour atlas
it is etc/nabox/harvest/user/restperf/custom.yaml since active is created at runtime by nabox - try renaming or mv this file
covert elbow
That looks better so do I just leave it disabled?
It is maybe an incorrect edit I made in the file or I just don't need it?
sour atlas
maybe you originally added it because you wanted to collect metrics for flexgroup constituents? If so, we can reenable that but for the correct template
covert elbow
What's the right template? Although my FlexGroup report does have data currently.
Based on this I thought the disabled custom.yaml template in the location we just disabled was correct - https://github.com/NetApp/harvest/discussions/3905
Awww it was a little different - mkdir -p /etc/nabox/harvest/user/rest
sour atlas
discussion 3905 mentions keyperf and zapiperf, not restperf. We removed your custom restperf template
covert elbow
Well I have a custom.yaml at this location /etc/nabox/harvest/user/rest and my Flexgroup data is mostly showing.
I created that custom.yaml long ago
sour atlas
yes, that will ensure the config-related flexgroup information is collected but that template will not collect performance metrics, only config.
I think what happened is a long time ago, you enable flexgroups with your custom yamls by following https://github.com/NetApp/harvest/discussions/3778 Notice this mentions chaning rest and restperf, which is what you did.
But 25.11 changed that, as mentioned in the release notes and https://github.com/NetApp/harvest/discussions/3905
covert elbow
That is correct because there is no performance data.
sour atlas
make sense. To add performance data follow the directions in #3905 for "Extend keyperf volume template"
covert elbow
Got it, I will follow those steps.
covert elbow
Funny. Anytime I still go and edit the harvest.yaml file I run into the same issue. I throw KeyPerf into the file and once again nothing changes.
I figure I will just leave the performance out for now.
sour atlas
we can get it working! Can you restart everything again, wait 5m, grab a support bundle and upload to https://upload.nabox.org/pade-yity-kabi again?
sour atlas
What was different this time?
covert elbow
I used a ASCII editori
sour atlas
ah ok, so maybe tabs vs space issue in the yaml
covert elbow
Yep
sour atlas
glad you got it working
covert elbow
Thanks for your help as always!
sour atlas
you're welcome!
covert elbow
Why is it when I add the KeyPerf to more than one system the other one stops working and the new one doesn't report any performance either?
I think I'll upload the logs.
Uploaded
sour atlas
can you tell me which poller is working and which one isnt?
{"log":"time=2026-01-15T18:55:51.482Z level=ERROR source=conf.go:75 msg="unable to load config" error="yaml: line 186: found a tab character that violates indentation"\n","stream":"stdout","time":
"2026-01-15T18:55:51.482301225Z"}
covert elbow
As in the actual system name?
sour atlas
the poller name
that's the collector name, the poller name is the name listed in the Pollers section of your harvest.yml
covert elbow
Without saying names, the very last system in the harvest.yaml file.
sour atlas
you said: "Why is it when I add the KeyPerf to more than one system the other one stops working and the new one doesn't report any performance either? "
I need to know the names of the system to compare them. If you can't say the poller name, please email us at ng-harvest-files@netapp.com and tell us the poller names
