Why Monitor MySQL Cluster?

Owing to the high availability and load-balancing capabilities, clustered databases are often the preferred backend in many mission-critical IT infrastructures delivering key end-user services. This is why, the non-availability of a clustered node to an application, or high transaction errors on the clustered node, or increase in the number of error/unreachable/offline nodes, or too many open or failed connections may cause the dependent end-user services to suffer. To avoid this, the MySQL Cluster should be continuously monitored. For this purpose, the eG Enterprise provides a specialized MySQL Cluster monitoring model. To use this model, only a single eG external agent is required; this agent sits on a remote host and determines the health of the target MySQL Cluster.
