Hey,
Well your housekeeping settings are to not delete RRDs unless they are not updated for 2 months.
Did this one device with 200GB RRDs have files older than 2 months?
If not then none of those RRDs will be deleted for now.

Hello,

I noticed that Observium started to use up lots of storage space. From ~200Gb it started to use ~400Gbs. Found interested thing, that one device RRD folder tooks ~200GBs instead of ~4-5Gbs. I'm always running housekeeping scripts in cron:

# Run housekeeping script daily for syslog, eventlog and alert log
13 5 * * * root /opt/observium/housekeeping.php -ysel >> /dev/null 2>&1

# Run housekeeping script daily for rrds, ports, orphaned entries in the database and performance data
47 4 * * * root /opt/observium/housekeeping.php -yrptib >> /dev/null 2>&1

But seems it doesnt help, and housekeeping log doesn't show errors.

Could someone advice how to clear that files in RRD folder according to housekeeping settings which are here:

infra [root@observ001prvitx logs]# cat /opt/observium/includes/defaults.inc.php  | grep housekeep

$config['housekeeping']['syslog']['age'] = '1M';         // Maximum age of syslog entries; 0 to disable
$config['housekeeping']['eventlog']['age'] = '3M';       // Maximum age of event log entries; 0 to disable
$config['housekeeping']['alertlog']['age'] = '3M';       // Maximum age of alert log entries; 0 to disable
$config['housekeeping']['authlog']['age'] = '6M';        // Maximum age of authlog entries; 0 to disable
$config['housekeeping']['inventory']['age'] = '1M';      // Maximum age of deleted inventory entries; 0 to disable
$config['housekeeping']['deleted_ports']['age'] = '1M';  // Maximum age of deleted ports before automatically purging; 0 to disable
$config['housekeeping']['rrd']['age'] = '2M';            // Maximum age of unused rrd files before automatically purging; 0 to disable
$config['housekeeping']['rrd']['invalid'] = TRUE;        // Delete .rrd files that are not valid RRD files (eg created with a full disk)

afaik M = month ?
