Changing performance data expiration times
Performance data stored in OpsCenter expires after configurable time periods.
cluster_name.conf
The location of the cluster_name.conf file depends on the type of installation:
- Package installations: /etc/opscenter/clusters/cluster_name.conf
- Tarball installations: install_location/conf/clusters/cluster_name.conf
- Windows installations: Program Files (x86)\DataStax Community\opscenter\conf\clusters\cluster_name.conf
The default values are designed to provide efficient compaction and eventual deletion of the data, with faster expiration times for the more granular, larger-volume data roll-ups.
- One-minute roll-ups (1min_ttl) expire after one week, or 604800 seconds.
- Five-minute roll-ups (5min_ttl) expire after four weeks, or 2419200 seconds.
- Two-hour roll-ups (2hr_ttl) expire after one year, or 31536000 seconds.
To change expiration time period:
In this example, the one-minute and five-minute roll-ups are set to expire twice as fast as the defaults, and two-hour roll-ups are set to be kept indefinitely (expiration is disabled).
