Going through our deployment and wanted to get FSA metrics enabled but don't really see how to do so.
Edited the harvest.yml file and added in Rest under a default collector but don't have anything being reported and no other docs that show if there is something else that needs to be turned on or how to do so.

@waxen flint Have you enabled FSA on ONTAP side as mentioned in FSA dashboard? https://docs.netapp.com/us-en/ontap/task_nas_file_system_analytics_enable.html

waxen flint Dec 20, 2023, 4:27 PM

#

yea, all of our volumes have FSA enabled

vast minnow Dec 21, 2023, 4:48 AM

#

@waxen flint Can you share Harvest logs with us @ ng-harvest-files@netapp.com. https://netapp.github.io/harvest/23.11/help/log-collection/

waxen flint Dec 21, 2023, 5:39 AM

#

logs emailed

vast minnow Dec 21, 2023, 5:41 AM

#

Thanks. I have not received yet.

#

Received

#

@waxen flint If you run volume_analytics_bytes_used_by_modified_time query in prometheus . Do you see any results?

#

Based on logs, I see 3 of the pollers are exporting metrics for FSA.

waxen flint Dec 21, 2023, 6:09 AM

#

it does return some results when running a promQL

vast minnow Dec 21, 2023, 6:09 AM

#

okay That is good. How about query volume_analytics_dir_bytes_used?

waxen flint Dec 21, 2023, 6:09 AM

#

it does return data as well

vast minnow Dec 21, 2023, 6:10 AM

#

Okay good. Let's go to FSA dashboard now and select all clusters (attached) from dropdown and see if Dashboard shows any data

waxen flint Dec 21, 2023, 6:12 AM

#

select all DC, all cluster, all SVM but volume only has the option of none

vast minnow Dec 21, 2023, 6:14 AM

#

okay. We should be getting volumes as they are part of metric volume_analytics_dir_bytes_used. Can you check if volume label is available in metric volume_analytics_dir_bytes_used ?

#

We use below query for populating Volume dropdown in FSA dashboard

waxen flint Dec 21, 2023, 6:16 AM

#

not sure what page that is you're on, i'm just on the explore page running a query, don't know if that matters, but it does list volume names

#

vast minnow Dec 21, 2023, 6:18 AM

#

I shared Grafana variable page screenshot. If volume is present then it should be loaded in Dashboard.

#

What is the Harvest version?

vast minnow Dec 21, 2023, 6:19 AM

#

Can you share screenshot of your FSA Grafana dashboard -> settings -> Variables

waxen flint Dec 21, 2023, 6:22 AM

#

not sure how to get to that page, i dont see anything like that with variables

#

nm, i see it

#

vast minnow Dec 21, 2023, 6:24 AM

#

This looks correct. If you click on Volume variable and change query to label_values(volume_analytics_dir_bytes_used{datacenter=~"$Datacenter",cluster=~"$Cluster"}, volume) Does it populate Volume dropdown?

#

waxen flint Dec 21, 2023, 6:29 AM

#

Error
invalid parameter "query": 1:1: parse error: unknown function with name "label_values"

vast minnow Dec 21, 2023, 6:30 AM

#

Can you share screenshot of your changes

waxen flint Dec 21, 2023, 6:30 AM

#

vast minnow Dec 21, 2023, 6:35 AM

#

Let me check in 9.5 grafana. My screenshots have been from 8.0

#

let's try this

#

Regex: .*volume=\"(.*?)\".*

#

Query: volume_analytics_dir_bytes_used{datacenter=~"$Datacenter",cluster=~"$Cluster"}

waxen flint Dec 21, 2023, 6:42 AM

#

still not showing anything on the dashboard and the query doesnt give an error it just doesn't come back with anything

#

the 'preview of values' on my screen just says "none" yours has several things

vast minnow Dec 21, 2023, 6:45 AM

#

Let's try changing query to just volume_analytics_dir_bytes_used

waxen flint Dec 21, 2023, 6:46 AM

#

that is showing several things listed at the bottom now

vast minnow Dec 21, 2023, 6:46 AM

#

That is great. It means one of filter either datacenter or cluster has issues.

#

Can you make sure when you make these changes, in dashboard dropdowns datacenter, cluster, svm are at All

waxen flint Dec 21, 2023, 6:47 AM

#

they are right now

vast minnow Dec 21, 2023, 6:47 AM

#

let's change query to volume_analytics_dir_bytes_used{datacenter=~"$Datacenter"} and check

waxen flint Dec 21, 2023, 6:47 AM

#

and i am getting results

vast minnow Dec 21, 2023, 6:48 AM

#

Yes but with our changes in query, filters will not work as expected as now we have made Volume loaded by default.

waxen flint Dec 21, 2023, 6:49 AM

#

changing it still shows results

vast minnow Dec 21, 2023, 6:49 AM

#

Do you mean original query for Volume volume_analytics_dir_bytes_used{datacenter=~"$Datacenter",cluster=~"$Cluster",svm=~"$SVM"} works as well?

waxen flint Dec 21, 2023, 6:50 AM

#

volume_analytics_dir_bytes_used{datacenter=~"$Datacenter"}
this works

vast minnow Dec 21, 2023, 6:50 AM

#

okay good

#

let's try volume_analytics_dir_bytes_used{datacenter=~"$Datacenter",cluster=~"$Cluster"} now

waxen flint Dec 21, 2023, 6:50 AM

#

do i need to remove the regex

vast minnow Dec 21, 2023, 6:51 AM

#

No

waxen flint Dec 21, 2023, 6:51 AM

#

ok, that change still shows data

vast minnow Dec 21, 2023, 6:51 AM

#

okay. Preview still shows value?

waxen flint Dec 21, 2023, 6:51 AM

#

yes

vast minnow Dec 21, 2023, 6:52 AM

#

okay let's change to volume_analytics_dir_bytes_used{datacenter=~"$Datacenter",cluster=~"$Cluster",svm=~"$SVM"}

waxen flint Dec 21, 2023, 6:52 AM

#

that is still showing results as well

vast minnow Dec 21, 2023, 6:53 AM

#

Good to click on Run Query after making changes

waxen flint Dec 21, 2023, 6:53 AM

#

yea, and the dashboard shows results as well

vast minnow Dec 21, 2023, 6:53 AM

#

okay great so We are back to original query then which is working

waxen flint Dec 21, 2023, 6:53 AM

#

but if i remove the regex it fails

vast minnow Dec 21, 2023, 6:53 AM

#

regex is needed

#

we need to keep regex

#

Let's save dashboard

waxen flint Dec 21, 2023, 6:54 AM

#

ok
this is the error it gives

invalid parameter "query": 1:477: parse error: unexpected identifier "peupdopstrnas01" in label matching, expected "," or "}"

vast minnow Dec 21, 2023, 6:54 AM

#

regex is needed

waxen flint Dec 21, 2023, 6:54 AM

#

yea, the dashboard is working

vast minnow Dec 21, 2023, 6:55 AM

#

Okay great! Our changes are same as what we shipped in 23.11. I suspect it was probably some dashboard loading issue

waxen flint Dec 21, 2023, 6:56 AM

#

strange.. there was no regex in the original dashboard, so maybe that was the big part of it
i'll have to go back through all of the dashboards and test more

vast minnow Dec 21, 2023, 6:56 AM

#

Actually we moved to query_result query which needs regex. Earlier we were using label_values which doesn't need regex

#

but both should give us same results.

#

You may try importing a fresh FSA dashboard in Grafana from here and see if it has any issues
https://raw.githubusercontent.com/NetApp/harvest/main/grafana/dashboards/cmode/fsa.json

waxen flint Dec 21, 2023, 7:00 AM

#

aye, deleting the existing one and importing it works
