Prometheus Exporter Snap for charm-juju-backup-all

The prometheus-juju-backup-all-exporter is a snap for collecting backup results from charm-juju-backup-all, and export those results as prometheus metrics. The metrics are expected to be used with prometheus.

Getting Started

Install the snap from snap store:

$ sudo snap install prometheus-juju-backup-all-exporter

Start the exporter:

$ sudo snap start prometheus-juju-backup-all-exporter

Snap Configuration

The install hook (./snap/hooks/install) will generate a default configuration for the exporter. By default, the exporter is started at port 10000 with a logging level of INFO.

You can change the default configuration by editing

$ /var/snap/prometheus-juju-backup-all-exporter/current/config.yaml

and then restart the snap by

$ sudo snap restart prometheus-juju-backup-all-exporter

Local Build and Testing

You need snapcraft to build the snap:

$ sudo snap install snapcraft --classic

Snapcraft also requires backend to create isolated build environment, you can choose the following two backends:

• LXD, which creates container image build instances. It can be used inside virtual machines.
• Multipass, which creates virtual machine build instances. It cannot be reliably used on platforms that do not support nested virtualization. For instance, Multipass will most likely not run inside a virtual machine itself.

To build the snap:

$ make build

To try the snap that was built, you can install it locally:

$ sudo snap install --devmode ./$(grep -E "^name:" snap/snapcraft.yaml | awk '{print $2}').snap
