Measures reported by MySQLCltOperTest
The MySQL Cluster distributed database helps in providing high availability and throughput for the MySQL database management system. If a user complains that his/her transactions with My SQL Cluster database are failing, administrators may first want to know which steps of the user interactions are failing often. The MySQLCltOperTest provides administrators with this useful information.
This test periodically monitors the status of the MySQL Cluster database server. Using the test, administrators an proactively be alerted when the cluster is non operational/stopped. In addition, this test throws light on the operations that were completed successfully and the operations that failed.
Outputs of the test : One set of results for the MySQL database cluster server being monitored.
