In Day Four - Monitoring and Health Checks we've covered probes and self healing. We then installed Prometheus and Grafana. And we finished up by installing a set of dashboards into Grafana.
The homework for Day Four is to deploy Prometheus and Grafana into your cluster.
Note
If either the Prometheus or Grafana Pod restarts then all the data for that Pod will be lost. This is because we are not using persistent storage. In the next section, Day Five - Persistence and Databases, we will install a storage solution into our cluster.
Now we move onto Day Five - Persistence and Databases.
