Disabling juju state metrics
It was found that for some large controllers where the metrics were being scraped into Prometheus, the collection of some metrics related to information stored in the database was slow and causing timeouts. To deal with this issue we have added a controller configuration feature to disable the gathering of those metrics.

This can be enabled using

juju controller-config features=[disable-state-metrics]

This can be set before upgrading to 2.4.7. The controller will need to be restarted if it’s done after upgrading.

Get Juju

The easiest way to install Juju is by using the snap package:

sudo snap install juju --classic

Those already using the ‘stable’ snap channel (the default as per the above command) should be upgraded automatically. Other packages are available for a variety of platforms (see the install documentation).
