Capacity Service

Using trend analysis and forecasting, the Capacity Service helps you understand how a cluster is performing within its current environment and workload, and gain a better sense of how time affects those trends, both past and future.

Using trend analysis and forecasting, the Capacity Service helps you understand how a cluster is performing within its current environment and workload, and gain a better sense of how time affects those trends, both past and future. Several types of metrics are collected by the Capacity Service, including Cassandra-specific and platform-specific metrics (for example, disk metrics, network metrics), at both the node and table level (where applicable). These metrics are stored in Cassandra on the cluster being managed by default. That metrics data can be stored on a separate dedicated cluster as well.

Trend Analysis 

The Trend Analysis component of the Capacity Service allows viewing historical metrics for any node or table, as well as aggregates across the entire cluster.

Forecasting 

Using the Forecast feature, view a predicted trend for any metric, based on historical data that has been collected.
