OpsCenter 4.1 User Guide

Configuring data collection and expiration

OpsCenter collects system and column family metrics data for each node in your cluster.

OpsCenter creates its own keyspace within a cluster for storing collected metrics. This data can also be stored on a cluster other than the one currently being managed by OpsCenter. Metrics data is collected at regular intervals and stored within your cluster in a keyspace called OpsCenter. The column families containing metric data continue to grow. You can configure how long you want to keep historical metrics. Data expires after configurable time periods.
