For management and deployment jobs, ClusterControl performs these jobs by pushing remote commands via SSH to the target node. Users only need to install the CMON controller package on the ClusterControl host, and make sure that passwordless SSH and the CMON database user GRANTs are properly set up on each of the managed hosts. This mechanism requires no agent which simplifies the setup of the whole infrastructure. Agent-based mode of operation is only supported for monitoring jobs, as described in the next section.
