View container logs

info

Prerequisite: For this lab, Loki and Grafana need to be activated.

When your application is deployed, you would of course like to be able to see container logs for debugging purposes. Grafana Loki is used in Otomi for log aggregation. When Grafana Loki is enabled, you'll see the Loki app in your apps.

info

Only when Otomi is configured in multi-tenant mode, container logs of teams are split up between teams. This means you can only see the logs of your own team. If multi-tenancy is not enabled, you can see the logs of all containers running on the cluster. If you don't want other teams to see your logs, ask the administrator to enable the Otomi multi-tenancy feature.

  • Open the Loki app in your team apps

In Grafana, you are directed to the Explore section. Otomi already added a query for you, showing the logs of all containers running in your team namespace

Adjust the query to your own needs. Loki uses LogQL as a query language. Learn more about LOgQL here
