Integrate with COS

In this guide, we will cover how-to integrate Vault K8s with Canonical Observability Stack (COS) for metrics, logs, and dashboards.

Pre-requisites:

• Juju >= 3.4

1. Deploy COS Lite

Create a model for observability:

juju add-model cos

Deploy cos lite and wait for all applications to be in active status:

juju deploy cos-lite --trust

Create offers for integrating with COS:

juju offer cos.prometheus:receive-remote-write
juju offer cos.loki:logging
juju offer cos.grafana:grafana-dashboard

2. Integrate with COS

Switch to the model in which Vault is deployed:

juju switch <vault model>

Deploy Grafana Agent:

juju deploy grafana-agent-k8s

Integrate Vault K8s with Grafana Agent:

juju integrate vault-k8s:logging grafana-agent-k8s
juju integrate vault-k8s:metrics-endpoint grafana-agent-k8s
juju integrate vault-k8s:grafana-dashboard grafana-agent-k8s

Consume the COS offers:

juju consume cos.prometheus
juju consume cos.loki
juju consume cos.grafana

Integrate Grafana Agent with COS:

juju integrate prometheus:receive-remote-write grafana-agent-k8s:send-remote-write
juju integrate loki:logging grafana-agent-k8s:logging-consumer
juju integrate grafana:grafana-dashboard grafana-agent-k8s:grafana-dashboards-provider

3. Access the Vault dashboard

Switch to the cos model:

juju switch cos

Retrieve the Grafana admin password:

juju run grafana/leader get-admin-password

Log in Grafana, and select the Vault dashboard.
