Abstract
A primary master node and a standby master node monitor the health of a shared nothing database appliance to afford high availability while minimizing false negatives and duplicate alerts by executing continuously in parallel complimentary processes that determine whether the database is running, and which master node is the active database master node. The active database master node monitors the health of the components of the database appliance by polling each component to detect failures and warnings, and the other master node monitors the status of the active master node. Upon detecting a failure of the active master node, the other node takes over health monitoring. If the database is not running, the designated primary master node performs health monitoring.
