"[juju] Host Details" dashboard doesn't select any metrcis and shows no data

[Aliaksandr Vasiuk]

Hi,

It is observed on multiple clouds that the default "[juju] Host Details" dashboard doesn't show any data.
I see that for the "Hostname" dropdown variables queried with "label_values(ceph_disk_occupation, exported_instance)". The `exported_instance` label of the `ceph_disk_occupation` metric contains hostnames.
Then the dashboard tries to put filer for example the "cpu_usage_user" metric by label "host" using the "hostname" value. But the label "host" of the "cpu_usage_user" metric contains value of "<juju_model:juju_unit>". And in the end the dashboard is not able to filter any data. I attached the example screenshot of how does it look.

The behavior is observed for grafana snap of version "7.5.17", using charms tracking "latest/stable" of revisions 66 and 51.

Best,
Alex.

This bug prevents us from seeing host metrics in PS6.

I'm not sure what dashboard is this, at least I could not see it [1].
FYI, this charm is deprecated.

Correct Robert's wording. This project is in maintenance mode. We will fix critical issues.

May I confirm does PS6 migrate to COS? If that is the case, this charm should not be installed. thanks!

Hi Eric,

Yes, COS migration is planned for the cloud, we are not going to use this charmed LMA Grafana after migration is completed. Thank you for the clarification.
