OpsCenter data growing too large

For OpsCenter versions prior to 3.2.1, truncate tables to reclaim space.

A bug fixed in 3.2.1 was not setting a TTL (time to live) on metrics data being collected for a managed cluster. Depending on your environment, this could cause some tables in the OpsCenter keyspace to grow too large. The most common offenders typically are the pdps (raw data points) and rollups60 (1m data points) tables.

If any of the tables have grown too large, you can truncate them to reclaim the space. If you are not comfortable losing historical data for that granularity (for example, 1m), please contact DataStax support.
