WebLogic Server provides a self-health monitoring capability to improve the reliability and availability of servers in a domain. Selected subsystems within each WebLogic Server instance monitor their health status based on criteria specific to the subsystem.

Use this page to configure the frequency of this server's automated health checks, and the frequency with which the Node Manager application (optional) checks the servers's health state. You can also use this page to specify whether Node Manager automatically stops and restarts the server if the server reaches the "failed" health state.
