Observability solution

The observability/monitoring solution for Raspberry Pi cluster is the following:

This solution allow to monitor application traces, logs and metrics providing a single pane of glass where all information from an application can be showed in dashboards.

Monitoring solution is based on the following components:

• Loki (logging)
• Grafana Tempo (distributed tracing)
• Prometheus (monitoring)
• Grafana (single pane of glass)

Logging solution is complemented with a log analytics solution based on Elasticsearch and Kibana.

Common log collection and distrution layer, implemented with fluentbit/fluentd, feeds logs to Log Analytics platform (ES) and Log Monitoring platform (Loki).

Observability solution installation procedure

The procedure for deploying observability solution stack is described in the following pages:
