The Cassandra Service Layer

The tests associated with this layer monitor the protocol through which clients communicate with the target database node, the nodes that are available/unreachable, the status of the gossip protocol service and the native protocol service, the large messages/small messages/gossip messages pending transfer to the joining node in the cluster. By executing the tests associated with this layer, administrators can monitor the message drop rate on the target database node and the long running queries executing on the database server.
