Because of this the Monitoring Add-On is required to be installed before installing the Log Management Add-On.
All logs provided via stdout or stderr by Pods in the cluster will be collected and stored for the configured retention time.
Loki is the database where all logs are stored.
Promtail runs as a DaemonSet and collects all logs from all nodes and sends them to Loki.
For information on how to install and uninstall an Add-On see MetaKube Add-Ons.
