check_postgres_bloat

Hi,

I'm running a the check_postgres.pl --action=bloat on a database and finding that there is wasted space.

I'm using 95% for the crtical %. If I use 110% I get the same things, but 115% shows everything is OK.

check_postgres_bloat -H host -p port -db thing -t thing1 -c 95%

check_postgres.pl version 2.14.3

postgres version 8.3.9

POSTGRES_BLOAT CRITICAL: service=thing1 (db thing) table public.thing1 rows:25537152 pages:212311 shouldbe:187545 (1.1X) wasted size:202883072 (193 MB) * (db thing) table public.thing2 rows:10109173 pages:101832 shouldbe:94016 (1.1X) wasted size:64028672 (61 MB) * (db thing) table thing3 rows:1184946 pages:28701 shouldbe:21434 (1.3X) wasted size:59531264 (56 MB) *


I have run a reindexdb on the table, full vacuum (fze), still I can't get the wasted size to go down on these, so I continue to get critical alerts that my tables are bloated.

check_postgres checks for both index and table bloat. It looks like my indexes are ok, this is just picking up on table bloat. I'm not sure what I can do to reclaim the wasted space other than vacuum full & analyze. Maybe a pgdump will do it.

Thanks for any insight,
~DjK
