Take a look at the pg_stat_archiver view, if you have not already: https://www.postgresql.org/docs/current/monitoring-stats.html#MONITORING-PG-STAT-ARCHIVER-VIEW
So I want to check how many wal file got created in x minutes and how many > .ready files got created in those x minutes. > It's not clear why you would want to track .ready files, they should be quite transient, and not a concern unless you are rolling your own archiving system (which you should not be). But Ron's suggestion of inotifywait is a good one for this. Probably listed as inotify or inotify-tools in your packaging system. Basic usage would be something like this, from the data directory: timeout 10m inotifywait pg_wal/ -r -m -e close_write -o walinfo.log Cheers, Greg -- Crunchy Data - https://www.crunchydata.com Enterprise Postgres Software Products & Tech Support
