I'm surprised I can't find the answer for this anywhere.
My filesystem on my JON server is over 80% and I can't figure out how to clean up the local metrics. Adding another storage node is not something we want to do at the moment as we are not using JON to its full potential and we are only monitoring a small number of servers.
I have found the document below that shows how to configure data retention, but my understanding is that this is the data stored in the DB and not in the filesystem.
3.6. Configuring How Long Monitoring Data Are Stored
Here's the current usage:
../rhq-data/storage
# du -sh *
1.1G commitlog
63G data
30M saved_caches
../rhq-data/storage/data/rhq
# du -sh *
479M metrics_index
31G one_hour_metrics
24G raw_metrics
152K schema_version
5.9G six_hour_metrics
1.8G twenty_four_hour_metrics
Looks like most data is stored in the the snapshots folder:
[root@server one_hour_metrics]# duch -G
1G ./snapshots/1407040202371
1G ./snapshots/1412483402010
2G ./snapshots/1404621001246
3G ./snapshots/1400992201259
3G ./snapshots/1403411403913
3G ./snapshots/1410064207226
22G ./snapshots
31G .
31G total
Thanks,
Victor.
