Check multiple network devices of a single host

Problem: A cluster server system may have multiple network interfaces  It is of interest to monitor all single devices for availability, while having the advantage to define only one host. – the host on which the network cards are installed.

First define the server as host in Nagios, before following the next steps. (This example configuration is accomplished in Würth Phoenix NetEye making use of the configuration manager Monarch)

  • Define on this host the service check “PING” defining in the command definition not the argument -H HOSTNAME but -H as one variable argument i.e $ARG1$
    Example command: “$USER1$/check_icmp -H $ARG1$ -w 1000.0,20% -c 1200.0,50% -p 5”
  • In the section “Multiple instances” define now an instance name for each network interface and click “Add Instance”
  • define now the specific arguments to pass as hostname of the network interface to check. For example pbzbs01eth04 stands in the example below for ethernet 04 on pbzbs01.

As shown in the screenshot below each instance gets the argument separated by ”!”, where the only argument is $ARG1$ for -H, the hostname on which to run the ping.

After my graduation in Applied Computer Science at the Free University of Bolzano I decided to start my professional career outside the province. With a bit of good timing and good luck I went into the booming IT-Dept. of Geox in the shoe district of Montebelluna, where I realized how a big IT infrastructure has to grow and adapt to quickly changing requirements. During this experience I had also the nice possibility to travel the world, while setting up the various production and retail areas of this company. Arrived at Würth Phoenix I started developing on our monitoring solution NetEye. Today, in my position as Product Manager, I aim to continuously improve our solutions and to adapt them to actual market requirements.
