Testing out the new NFS Latency Heatmap in 23.08 release... For some reason, I'm not seeing NFSv4/v4.1 heatmaps. Mouseover shows error "u is undefined"

Checked conf/zapiperf/default.yaml, but not finding anything obvious to enable here.

Appreciate any pointers.

Thanks!

hi @latent raft at the top of the dashboard do your variables contain the datacenter, cluster, etc with valid values? These heatmaps were moved into there own rows like this

Can you check your Prometheus instance to make sure the counters are being reported? Try svm_nfs_latency_hist_bucket in the expressison field like so

Looks like I'm getting hits on v3 only. No v4 at all

How did you install Harvest? These counters are collected by zapiperf or restperf, which collector are you using and we can double check that your template is correct and there are no collection errors

Ok. That's likely my issue... I've imported this dashboard from the Harvest tgz so not the full install. We are at 23.05 in the lab.
I can have them push the entire package out and verify if that fixes this.

ah yes that's why, nfsv4+ did not have the latency_hist counters in 23.05, those were added in 23.08
