DataStax agents must be installed on every managed node in a cluster and are necessary to perform most of the functionality within OpsCenter. When creating a new cluster with Lifecycle Manager, the DataStax agent is automatically installed. When adding a new cluster to manage with OpsCenter, you are given the option to automatically or manually install agents.

Install Agents automatically or manually dialog

If there are any issues with installing agents, a banner at the top of the OpsCenter workspace is displayed. The banner cannot be dismissed until the agent issues have been resolved but the banner does not prevent using or navigating the OpsCenter UI. Clicking the Show Details link in the banner displays the clusters having agent issues and the number of problems currently detected by OpsCenter.
