Oracle WebLogic Remote/Outbound URL Monitoring

WLSDM Support

OHS Health/Webpage URL monitoring is quite simple to create then take action when instance/URL:port performance exceeds the threshold. The DevOps MBean consists of the following file parts: WLSDM-LinuxURLPortMonitoring.sh, WLSDM-URLProperties, WLSDM-Health.sh and WLSDM-WebServer.conf.
