Question

I am using check_http plugin for discovering jenkins service(Winstone hosted and Apache hosted) is running or not on hosts on which check_mk_agent is installed. And its been monitored on single ui that is nagios GUI, using following command.

./check_http -H Host_Name -u /api/xml?depth=0 -p 8080

Next step is to parse the jobs on specific jenkins master server using jenkins REST api and monitor each job’s health in nagios GUI.

Could someone please give me any idea on this so that I can monitor the jenkins jobs on single GUI. Any script or plugin much appreciated.
