pgincident vs pg_activity and pgcenter: A Honest Look at Postgres Triage Tools

A software developer has published a detailed comparison of three terminal-based PostgreSQL monitoring tools — pg_activity, pgcenter, and their own pgincident — to clarify where each fits during database incidents. pg_activity, a mature Python-based tool, excels when SSH access to a production host is available, displaying running queries sorted by duration without manual querying. pgcenter, written in Go, stands out on self-managed Linux servers by correlating OS-level metrics like CPU and I/O with Postgres stats on a single screen, helping engineers distinguish host-level problems from query-level ones. The author recounts a real incident where pgcenter identified I/O saturation and excessive checkpoints as the root cause of threefold API latency within seconds. pgincident is positioned not as a universal replacement but as a narrower tool suited for managed Postgres environments accessed from a Mac during first-response triage.
