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):
[tl-sg108e]
address 127.0.0.1
use_node_name no
In /etc/munin/plugin-conf.d/munin-node add the following entry:
[tl_sg]
host_name tl-sg108e
env.host 192.168.1.12
env.port 80
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
name as a configuration section as described above.
