Measures reported by MySQLCltStsTest
This test reports the count of nodes in the target MySQL database cluster and indicates the number and names of those nodes that are currently available. This way, the nodes that are unresponsive/unreachable can be identified. The test also reports the nodes that are in recovering state. Using this test, administrators can figure out if only very few nodes in the cluster are available to service the client requests to the cluster. This signals a potential overload.
Outputs of the test : One set of results for the MySQL cluster database server being monitored.
