Обсуждение: vacuum monitoring question

Hi All;

I'm working on a vacuum monitor script to alert us when tables start to grow out of control per dead space. Initially I excluded the system catalog schemas (pg_catalog, pg_toast, etc) however I wonder if maybe I should monitor these as well. PLus I'm looking for any input as to specifically what to look for - I've calculated a 'fill factor' which shows the average page fill as a percentage but I wonder what other metrics may help monitor possible problem tables effeciently..

Thoughts ?

Thanks in advance

It's a good idea to keep an eye on system catalogs, especially if you
have a fair bit of DDL going on in your usage.  I'd take a look at
what the check_postgresql.pl script does.  No need to reproduce all
that work on your own.

Thanks for the feedback - where can I find the check_postgresql.pl script ?
