Example 1 with ClusterRef

use of com.sun.enterprise.config.serverbeans.ClusterRef in project Payara by payara.

the class CreateHTTPHealthCheckerCommand method createHealthCheckerInternal.

/**
 * This is to create a health checker for a cluster configuration. By
 * default the healh checker will be configured.  This applies only
 * to our native load balancer.
 *
 * @param   url   the URL to ping so as to determine the health state
 *   of a listener.
 *
 * @param   interval   specifies the interval in seconds at which health
 *   checks of unhealthy instances carried out to check if the instances
 *   has turned healthy. Default value is 30 seconds. A value of 0 would
 *   imply that health check is disabled.
 *
 * @param   timeout    timeout interval in seconds within which response
 *   should be obtained for a health check request; else the instance would
 *   be considered unhealthy.Default value is 10 seconds.
 *
 * @param   lbConfig    the load balancer configuration bean
 * @param   lbConfigName    the load balancer configuration's name
 *
 * @param   target      name of the target - cluster or stand alone
 *  server instance
 *
 * @throws CommandException   If the operation is failed
