Add this to the relevant munin-node config file. You can specify switch address, username, password and description for each port

(the switch management doesn't allow port descriptions)

(the switch management doesn't allow port descriptions). You should also create a fake host for the switch and attach the graphs to it.

Details here: https://cweiske.de/tagebuch/munin-multiple-hosts.htm

In /etc/munin/munin.conf add a new host called tl-sg108e (or whatever you want):


  		




  
  45
  
    
  [tl-sg108e]


  		




  
  46
  
    
    address 127.0.0.1

    use_node_name no 


  		




  
  48
  
    

  		




  
  49
  
    
In /etc/munin/plugin-conf.d/munin-node add the following entry:


  		




  42
  50
  
    

  		




  43
  51
  
    
  [tl_sg]


  		




  
  52
  
    
  host_name tl-sg108e


  		




  44
  53
  
    
  env.host 192.168.1.12


  		




  45
  54
  
    
  env.port 80

  55
  
    
  env.numberOfPorts 8

  env.p7 'Not used'

  env.p8 'Uplink'

The name in host_name must match the name defined in munin.conf, and the tl_sg name must match the plugin instance name (symlink).

If you're monitoring multiple switches, create different symlinks in /etc/munin/plugins pointing to this plugin and use the symlink
