meta-monitoring-chart
This is a meta-monitoring chart for Loki, specifically Loki installed via the Loki helm chart.
Local and cloud modes
The chart has 2 modes: local and cloud. In the local mode logs, metrics and/or traces are sent to small Loki, Mimir and Tempo installations running in the meta-monitoring namespace.
In the cloud mode the logs, metrics and/or traces are sent to Grafana Cloud.
Both modes can be enabled at the same time. Cloud mode is preferred.
Installation
For more instructions including how to install the chart go to the installation page.
Supported features
- Specify which namespaces are monitored
- Specify if logs, metrics or traces should be enabled for cloud or local
- Specify the cluster name used for the logs, metrics and traces
- Specify PII regexes that are applied to logs before they are sent to Loki (cloud or local). The capture group in the regex is replaced with *****.
- a Grafana instance is installed (when local mode is used) with the relevant datasources installed. The following dashboards are installed:
- logs dashboards
- Alloy dashboards
Most of these features are enabled by default. See the values.yaml file for how to enable/disable them.
Caveats
- This has not been tested on Openshift yet.
- The underlying Loki, Mimir and Tempo are at the default size installed by the Helm chart. This might need changing when monitoring bigger Loki, Mimir or Tempo installations.
- MinIO is used as storage for the local mode at the moment with a limited retention. At the moment this chart cannot be used for monitoring over longer periods.
