prometheus-juju-exporter snap collects machines' running status in all models under a Juju controller. It also provides an interface to expose the metrics to Prometheus for storage and further usage.

To get the latest stable version of the snap from Snapstore, run:

sudo snap install prometheus-juju-exporter

To get the latest development version of the snap, build from the source code and install with --dangerous flag:

make build
sudo snap install --dangerous prometheus-juju-exporter.snap

By default, prometheus-juju-exporter uses the configuration specified in config_default.yaml. It's likely not fitting your need because the values provided are generic and for demonstration purposes only. To configure the snap for your own environment, create a config.yaml file in $SNAP_DATA (see Snap Environment Variables) directory with the desired entries.

The snap requires juju user's credentials to connect to a controller and all of its models. The credentials are set as juju.username and juju.password config values. Normally, superuser privilege is expected for such a user for full access to the controller. However, in case it is not possible, the minimum privilege requirements are:

1. login access to the controller instance and admin access to the model hosting the controller
2. admin access to any model that's expected to be monitored by this exporter
