Solved: Majordomo only collecting data in one of my three networks

Software SW help
1

Hello,

I am struggling to configure Majordomo to collect data in my environment.

I have got a setup leveraging three different networks (VLANs, Wifi):

  • lan (br-lan) where all devices are located over which I have full control
  • dmz (br-dmz) where all the IoT/SmartDevices are located
  • guest (br-guest) for my guests

Besides of the missing reverse DNS functionality Majordomo works fine for lan.
But no devices of my other two networks are shown …

If I got it correctly Majordomo is a set of plugins for lcollect. So I included all my networks in the lcollect configuration - without any success.

Did anybody find a solution for such a setup ?

Thanks Basil

Yes, you should list all the interfaces in /etc/config/lcollect like this:

package 'lcollect'

config interface
        option ifname 'br-lan'
config interface
        option ifname 'br-dmz'
config interface
        option ifname 'br-guest'

That should be enough.

Hello Ondrej,
I was only playing with the settings in the GUI - and not going to the config file …
I tested your suggestion over the weekend and majordomo now displays all devices in all networks :slight_smile:

Thanks for the solution !

If one interface is not up, unfortunately, lcollect stops, and does not collect from the working interfaces.

This should go to the developers of lcollect/majordomo, please file an issue.
