# How to integrate with COS ## Integrate with Prometheus K8s operator Deploy and integrate [`prometheus-k8s`](https://charmhub.io/prometheus-k8s) charm with `wordpress-k8s` charm through the `metrics-endpoint` relation via `prometheus_scrape` interface. Prometheus should start scraping the metrics exposed at `:9117/metrics` endpoint. ```default juju deploy prometheus-k8s juju integrate wordpress-k8s prometheus-k8s ``` ## Integrate with Loki K8s operator Deploy and integrate [`loki-k8s`](https://charmhub.io/loki-k8s) charm with `wordpress-k8s` charm through the `logging` relation via `loki_push_api` interface. Promtail worker should spawn and start pushing Apache access logs and error logs to Loki. ```default juju deploy loki-k8s juju integrate wordpress-k8s loki-k8s ``` ## Integrate with Grafana K8s operator In order for the Grafana dashboard to function properly, Grafana should be able to connect to Prometheus and Loki as its datasource. Deploy and integrate the `prometheus-k8s` and `loki-k8s` charms with [grafana-k8s](https://charmhub.io/grafana-k8s) charm through the `grafana-source` integration. Note that the relation `grafana-source` has to be explicitly stated since `prometheus-k8s` and `grafana-k8s` share multiple interfaces. ```default juju deploy grafana-k8s juju integrate prometheus-k8s:grafana-source grafana-k8s:grafana-source juju integrate loki-k8s:grafana-source grafana-k8s:grafana-source ``` Then, the `wordpress-k8s` charm can be integrated with Grafana using the `grafana-dashboard` relation with `grafana_dashboard` interface. ```default juju integrate wordpress-k8s grafana-k8s ``` To access the Grafana dashboard for the WordPress charm, run the `get-admin-password` action to obtain credentials for admin access. ```default juju run grafana-k8s/0 get-admin-password ``` Log into the Grafana dashboard by visiting `http://:3000`. Navigate to `http://:3000/dashboards` and access the WordPress dashboard named **Wordpress Operator Overview**.
