Task 3.1.1: Install Grafana

Similar to the basic setup, we are just going to update our configuration of the ArgoCD application to install and create our Grafana instance. Update your monitoring application (charts/user-monitoring/values.yaml) and update the grafana.enabled flag to true:

charts/user-monitoring/values.yaml:

user: <user> # Replace me
# prometheus
prometheus:
 enabled: true
# thanos-query
query:
 enabled: true
# grafana
grafana:
 enabled: true
# blackboxexporter
blackboxexporter:
 enabled: false
# pushgateway
pushgateway:
 enabled: false
# alertmanager
alertmanager:
 enabled: false
# thanos-ruler
ruler:
 enabled: false

Verify the installation and sync process in the ArgoCD UI . When the application is synchronized successfully navigate to your freshly created Grafana instance: https://<user>-grafana.training.cluster.acend.ch . Use the admin account to login in. Skip the password change.

Task 3.2.1: Import a dashboard

As a first Task we import an existing dashboard to our grafana. There is a huge collection of predefined dashboards available on https://grafana.com/grafana/dashboards .

In this task we learn how to import existing dashboards, which we can also use as reference to write our own queries and dashboards.

Choose one or more of the preexisting dashboards from https://grafana.com/grafana/dashboards and import them into your grafana. Use the daterange, interval picker on the top right to change the timerange (between 5 minutes and 10 minutes) of the displayed mertics.
