node-details-info:

Correct counter is lun-info and not node-details-info, changing this fixes data collection

Good catch @hashi825 thanks!

[cgrinds]

Question for you @hashi825 - Can you check and make sure you're getting the correct name

I also had to change

harvest/conf/zapi/cdot/9.8.0/lun.yaml

Line 23 in d480377

split: path `:` ,,,lun

to
split: path '/' ,,,lun

Before lun is blank

lun_size{datacenter="DC-01",cluster="sim-0001",node="",qtree="",lun="",volume="vol-460",svm="vserver-39"} 42949672960

After lun is correct

lun_size_used{cluster="sim-0001",datacenter="DC-01",node="",qtree="",lun="lun-490",volume="vol-460",svm="vserver-39"} 42949672960

Looks like node and qtree need fixing too.

[hashi825]

You're right, I changed the split and now get the lun name, I'm getting the correct node label though. Can't comment on qtrees since I don't have them in my environment.

[cgrinds]

Excellent - updated the PR with the path fix and good to hear node label is correct for you. That's likely an issue on my end.

Verified the issue and the fix works with out any issues.Observed lun name and size details are displayed correctly.
