Cluster Manager is a CA Spectrum feature that models and monitors your cluster environment and is intended for administrators. Cluster Manager provides an enterprise-wide view of your cluster environments, showing both topology and the logical relationships among your cluster components. Cluster Manager also provides visibility into useful metrics and helps you pinpoint and effectively troubleshoot problems by applying unique fault isolation techniques.

A key challenge when monitoring your cluster environment is tracking where work is occurring, or identifying the active nodes. Clustering technology is designed to sustain high availability for your server-based applications by providing a fail-safe environment. Resource groups move from one cluster node to another when needed, resulting in the distribution of work and node status changing periodically. Cluster Manager keeps up with these activities by continuously monitoring your cluster components, and quickly notifies you of any changes to your environment.
