1. A method for configuring a monitor services cluster that includes at least one replication quorum consisting of multiple monitor service nodes, said method comprising: determining target entity membership within a service domain including identifying a target entity to be monitored within a service domain, wherein said identifying a target entity comprises determining that the target entity is a service host that is configured to deploy monitor service nodes to monitor target entities within the service domain; in response to a registration request that specifies a monitor service node having an associated monitor services container that instantiates a plurality of monitor services that share an execution space, comparing a performance attribute of said service host with a service requirement of the monitor services; determining a monitor service coverage attribute of the at least one replication quorum; comparing a monitor service coverage attribute of the monitor service node specified by the registration request with a monitor service coverage attribute of the at least one replication quorum; and generating a response to the registration request based, at least in part, on said comparing the performance attribute with the service requirement and said comparing the monitor service coverage attribute of the monitor service node specified by the registration request with the monitor service coverage attribute of the at least one replication quorum, said generating the response to the registration request including, in response to determining that the performance attribute meets or exceeds the service requirement and based on a result of said comparing the monitor service coverage attribute of the monitor service node specified by the registration request with the monitor service coverage attribute of the at least one replication quorum, incorporating the monitor service node within the monitor services cluster including incorporating the monitor service node within one of the at least one replication quorum.
