CPU / Ping charts go back to "No Data" on refresh

[fireheadman]

Liking the dashboard!... I'm on Ubuntu 20 also. Followed the guide to a "T" but getting some off behaviors:

Unsure why, but when the CPU and Ping charts refresh, it goes back to "No Data" The CPU Temp I am unsure if it will register since I am on a VM ?

Also, I am not seeing anything in the Local Validators

UPDATE: for this post only.... Was able to resolve this by editing the prometheus.yml and changing all the "127.0.0.1" references to "localhost" and restarting prometheus. Now the CPU and Ping charts are persistent on refresh cycles.

Also, my Hourly Return just started to pop in, however nothing else is populating. Was expecting Hourly Earnings to show by now.

Here is another issue I am seeing Tiny print on the Participation Rate / Network Liveness and Huge Red message in the Avg.Balance

This might be a timing issue after all....?? I noticed at the top right, the time range selector was at "Last 2 days". I moved this to "Last 15 minutes" and the graphs look much better!

NOTE: Still looking into the CPU Temp, however I may just nuke this graph and make room for integrating the ALERTING metrics from the EthStakers grafana dashboard UPDATE: From what I have seen... FreeNas does not pass CPU Temp to VMs, so I cannot monitor this metric.

This can be closed out.... Was also able to create the alerting metrics from the EthStakers Dashboard

I will continue looking for why the DISK USAGE metric is not properly reporting, looks like node_exporter needs to be tuned to pick up the "/" root filesystem only.

found the issue on the filesystem monitoring not reporting... this may help others, just a matter of tuning to your system (as you mentioned) For the Query (sum(node_filesystem_size_bytes{device="/dev/mapper/ubuntu--vg-ubuntu--lv",job="node_exporter"})-sum(node_filesystem_avail_bytes{device="/dev/mapper/ubuntu--vg-ubuntu--lv",job="node_exporter"}))/sum(node_filesystem_size_bytes{device="/dev/mapper/ubuntu--vg-ubuntu--lv",job="node_exporter"})*100

Then add an alert

fireheadman@eth01:~$ df -hP /
Filesystem                         Size  Used Avail Use% Mounted on
/dev/mapper/ubuntu--vg-ubuntu--lv  491G  329G  141G  71% /
