Prometheus disk space consumption evaluation

21,212

This dashboard can be useful when evaluating the disk space usage of Prometheus data, when deployed in a Kubernetes cluster.

It correlates the disk usage of the persistent volume with prometheus events: compaction, size/time retention.

It shows:

• disk space used on the persistent volume (reported by the metric "kubelet_volume_stats_used_bytes" published by kubelet)
• compaction events (reported by the metric "prometheus_tsdb_compactions_total" published by Prometheus)
• time retention events
• size retention events
