Configuring Management Service Database Limits

Configuring database service limits lets you control the amount of retained monitoring data.

Minimum Required Role: Cluster Administrator (also provided by Full Administrator) This feature is not available when using Cloudera Manager to manage Data Hub clusters.

Each Cloudera Management Service role maintains a database for retaining the data it monitors. These databases (as well as the log files maintained by these services) can grow quite large. Limits on these data sets are configured when you create the management services, but you can modify these parameters through the Configuration settings in the Cloudera Manager Admin Console. For example, the Event Server lets you set a total number of events to store.

There are also settings for the logs that these various services create. You can throttle how big the logs are allowed to get and how many previous logs to retain.
