Integrate with COS

Deploy COS Lite

Create a Juju model and deploy the Canonical Observability Stack bundle cos-lite to this model:

juju add-model cos-lite
juju deploy cos-lite --trust

Expose the application relation endpoints

Once all the COS Lite applications are deployed and settled down (you can monitor this by using juju status --watch 2s), expose the relation points for Prometheus, Loki and Grafana:

juju offer prometheus:metrics-endpoint
juju offer loki:logging
juju offer grafana:grafana-dashboard

Validate that the offers have been successfully created by running:

juju find-offers cos-lite

You should see something similar to the output below:

Store                 URL                        Access  Interfaces
tutorial-controller  admin/cos-lite.loki        admin   loki_push_api:logging
tutorial-controller  admin/cos-lite.prometheus  admin   prometheus_scrape:metrics-endpoint
tutorial-controller  admin/cos-lite.grafana     admin   grafana_dashboard:grafana-dashboard

Integrate Hockeypuck

Switch back to the charm model and integrate your charm with the exposed endpoints:

juju switch <Hockeypuck charm model>
juju integrate hockeypuck-k8s admin/cos-lite.grafana
juju integrate hockeypuck-k8s admin/cos-lite.loki
juju integrate hockeypuck-k8s admin/cos-lite.prometheus

Ensure that Hockeypuck and the COS Lite applications are settled down (you can monitor this by using juju status --watch 2s).

Obtain the Grafana dashboard credentials by running the get-admin-password action:

juju switch cos-lite
juju run grafana/0 get-admin-password

This action returns the URL and the admin password to access the Hockeypuck dashboard. Now, on your host machine, open a web browser, enter the Grafana URL, and use the username “admin” and your Grafana password to log in. Under Home > Dashboards, you should be able to see the Hockeypuck dashboard listed.

This effectively integrates your application with Prometheus, Loki, and Grafana.
