Hello
We are facing issue that our /var/lib/centreon is nearly full and we don’t understand which files should be deleted to free some space.
In recent day it started filling up drastically.
In /var/lib/centreon(15GB) directory /var/lib/centreon/metrics directory consuming 11GB, It contain .rrd files from 2020.
Can you please help me to free some space at /var/lib/centreon ?
which files should i delete?
Is it safe to delete old .rrd files?
Thank You

hello
RRD are generated for each metrics (check with performance data), as far as I know there is no way to delete them as is, it needs to be done with knowing what to query in the database
however if the file have not been modified recently, meaning they are not linked to actively checked service, they could be safe to delete, but I would wait for a centreonian to confirm you can do that safely
this will tell you the size of all rrd older than 365 days (maybe even 30 days?)
find /var/lib/centreon/metrics -maxdepth 1 -type f -mtime +365 -print0 | du -hc --files0-from - | tail -n -1
to delete, here is the command:
find /var/lib/centreon/metrics -maxdepth 1 -type f -mtime +365 -exec rm {} \;
if you did an update of the platform and there are some checks that uses “global” metrics, or autodiscover, it can generate a lot of data because of new plugins, new checks…
however, please consult this article Prerequisites | Centreon Documentation you should not have a 16GB partition for /var/lib/centreon

Hello Cm123,
you re lucky to only have 1.3G, check mine
38G
But the reason i am here is that why you dont add more space to /var/lib/centreon??
Mine is 54G for exemple, because if you delete the files safely right now maybe you will have to delete it again soon.
it's not a long-term solution.
