Server --> Configuration --> Health Monitoring

Tasks Additional Documentation Attributes

Overview

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.

Attributes

Attribute Label | Description | Value Constraints
--- | --- | ---
Auto Restart | Enables/Disables automatic restart of a crashed server by the Node Manager. MBean: weblogic.management. configuration.ServerMBean Attribute: AutoRestart | Default: true Configurable: yes Dynamic: yes Readable: yes Writable: yes
Auto Kill If Failed | Enables/Disables automatic kill of a Failed server by the Node Manager. MBean: weblogic.management. configuration.ServerMBean Attribute: AutoKillIfFailed | Default: false Configurable: yes Dynamic: yes Readable: yes Writable: yes
Restart Interval | Interval (in seconds) during which a server can be restarted RestartMax times. MBean: weblogic.management. configuration.ServerMBean Attribute: RestartIntervalSeconds | Units: seconds Minimum: 300 Maximum: 2147483647 Default: 3600 Configurable: yes Dynamic: yes Readable: yes Writable: yes
Max Restarts within Interval | Number of times a server can be restarted within an interval of RestartIntervalSeconds seconds. MBean: weblogic.management. configuration.ServerMBean Attribute: RestartMax | Minimum: 0 Maximum: 2147483647 Default: 2 Configurable: yes Dynamic: yes Readable: yes Writable: yes
Health Check Interval | Periodicity (in seconds) of the server's health checks. This controls the frequency of the server's self-health monitoring and the Node Manager's health queries. MBean: weblogic.management. configuration.ServerMBean Attribute: HealthCheckIntervalSeconds | Units: seconds Minimum: 1 Maximum: 2147483647 Default: 180 Configurable: yes Dynamic: yes Readable: yes Writable: yes
Health Check Timeout | Time (in seconds) the Node Manager should wait before timing out its health query to the server. MBean: weblogic.management. configuration.ServerMBean Attribute: HealthCheckTimeoutSeconds | Units: seconds Minimum: 1 Maximum: 2147483647 Default: 60 Configurable: yes Dynamic: yes Readable: yes Writable: yes
Restart Delay Seconds | Time (in seconds) the Node Manager should wait before restarting the server. This value will be used in cases such as the OS not allowing listen ports to be reused immedietly. MBean: weblogic.management. configuration.ServerMBean Attribute: RestartDelaySeconds | Units: seconds Minimum: 0 Maximum: 2147483647 Default: 0 Configurable: yes Dynamic: yes Readable: yes Writable: yes
