Grafana dashboard: PostgreSQL Checkpoints and WAL Usage
Description: Percona Monitoring and Management dashboard with information on checkpoints and WAL usage for PostgreSQL.

This dashboard for Percona Monitoring and Management has information on checkpoints and WAL usage for PostgreSQL. It needs the postgresql_wal_bytes metric, which is calculated with pg_current_wal_lsn and pg_wal_lsn_diff (https://github.com/guriandoro/percona_live_23/blob/master/pmm_wal_bytes.sh).
