hscloud monitoring

Quick links

  • Old Global Dashboard: monitoring.hackerspace.pl - old monitoring system, unrelated to this one, configured using Chef at management.hackerspace.pl (long since dead). This setup is supposed to replace it.

Architecture

The hscloud monitoring solution is two-tiered:

  • at the global tier we run metrics aggregation, long-term storage, dashboard and alerting.
  • at the agent tier we collect metrics from various sources (possibly even lower tiered agents).

All agent-tier agents send metrics to all global instances.

Agent - cluster

Cluster agents are responsible from collecting Kubernetes cluster metrics. They run a prometheus server that scrapes kubelet/cadvisor/... metrics and send them off to global instances.

Global Instances

Global agents run Victoria Metrics, ingest metrics from all agents, and perform long-term storage. In the future they will also run Grafana and AlertManager.
