# Clusters: Configuration: Health Monitoring

Configuration Options Related Tasks Related Topics

This page allows you to configure the health monitoring characteristics for this cluster. WebLogic Server provides a self-health monitoring capability to improve the reliability and availability of servers in a WebLogic Server domain. Selected subsystems within each server monitor their health status based on criteria specific to the subsystem.

#### Configuration Options

Name | Description
--- | ---
Inter-Cluster Comm Link Health Check Interval | If the cluster link between two clusters goes down, a trigger will run to periodically to see if the link is restored. The duration is specified in milliseconds. MBean Attribute: `ClusterMBean.InterClusterCommLinkHealthCheckInterval`
Health Check Interval | Interval in milliseconds at which Migratable Servers and Cluster Masters prove their liveness via the database. MBean Attribute: `ClusterMBean.HealthCheckIntervalMillis` Changes take effect after you redeploy the module or restart the server.
Health Check Periods Until Fencing | Maximum number of periods that a cluster member will wait before timing out a Cluster Master and also the maximum number of periods the Cluster Master will wait before timing out a Migratable Server. MBean Attribute: `ClusterMBean.HealthCheckPeriodsUntilFencing` Minimum value: `2` Changes take effect after you redeploy the module or restart the server.
Fencing Grace Period | During automatic migration, if the Cluster Master determines a server to be dead, it waits for this period of time (in milliseconds) before the Cluster Master migrates the service to another server in the cluster. MBean Attribute: `ClusterMBean.FencingGracePeriodMillis` Changes take effect after you redeploy the module or restart the server.
