Query Explanation

The query uses increase() over a 30‑second window to count new occurrences of the error no more connections allowed (max_client_conn) from the pgbouncer_errors_count metric. If the count is greater than 0 (i.e., at least one new max‑client‑connection error appears), the alert fires.
