Nagios Interface

Nagios is running on the master servers of both installations. You need to have the access coordinates and a tunnel to connect to the web interface. Here the recipe to setup tunnel:

  • Assume you have defined a tunnel to the master system in $HOME/.ssh/config, e.g.
    Host qmasterW
    User user
    Hostname qmasterW
    ProxyCommand ssh user@qlogin.qpace.uni-wuppertal.de nc %h 22
  • Now start ssh connection:
    ssh qmasterW -L 20000:localhost:80
  • Finally, connect to web interface:
    firefox http://localhost:20000/nagios/

You may use another local port.

Important: The last slash in the NAGIOS URL is mandatory; if you do not specify it, the page will not be displayed.
