Curator¶
From https://www.elastic.co/guide/en/elasticsearch/client/curator/current/about.html#about:
Elasticsearch Curator helps you curate, or manage, your Elasticsearch indices and snapshots by:
- Obtaining the full list of indices (or snapshots) from the cluster, as the actionable list
- Iterate through a list of user-defined filters to progressively remove indices (or snapshots) from this actionable list as needed.
- Perform various actions on the items which remain in the actionable list.
Configuration¶
Curator actions are stored in /opt/so/conf/curator/action/. These actions are run by cron jobs managed by Salt.
Curator defaults to closing indices older than 30 days. To modify this, change cur_close_days in /opt/so/saltstack/local/pillar/minions/$SENSORNAME_$ROLE.sls.
As your disk reaches capacity, Curator starts deleting old indices to prevent your disk from filling up. To change the limit, modify log_size_limit in /opt/so/saltstack/local/pillar/minions/$SENSORNAME_$ROLE.sls.
New configurations should be added in /opt/so/saltstack/local/salt/curator/files/action/ and will be copied into /opt/so/conf/curator/action/.
Logs¶
When Curator completes an action, it logs its activity in a log file found in /opt/so/log/curator/.
