Hi guys,

i noticed my mongoDB will grow fast with massively samples and meters of
ceilometer. That's normal with a mass on tracking data but i need to
drop samples after a while o held my db clean so i take a look on
ceilometer-expirer (no documentation present).

I've found the option
time_to_life = <seconds>

ceilometer-expirer will check this option and drop all samples
>time_to_live ... so the theory ...

My database is now 96GB and i test the expirer with different
time_to_live values but i can't see any drop in my database.
I've checked it with mongostats to look wich operations are triggered
but i see only inserts, updates and selects.


Is there any trick  because i can't find any doc, troubleshoot or bug
report about this issue. I need to clean my db otherwise i can't get
data because my search queries with the ceilometer client times out.


System:
* Ubuntu 12.04
* Havana release
* MongoDB  2.6.4 (replicaSet)


Cheers and Thanks
Heiko
