Prometheus Juju Exporter

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.

Deployment

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

Configuration

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
