add Munin-Node to opnSense

[vikozo]

hello
i wish to add Munin-node to opnSense and found this tutorial.
https://zedt.eu/tech/linux/installing-munin-node-on-opnsense/

first question on debian i use vim-nox for editing, is it possible to use it on freebsd/opnSense too? going mad with vi for add/delete some caracters.

on the Tutorial it say to add in  /etc/rc.conf
munin_node_enable="YES"

the Problem i don't have a rc.conf
so where should i add it?

have a nice day

Hi vinc,

Creating the file is the way to go

# echo 'munin_node_enable="YES"' >> /etc/rc.conf


Cheers,
Franco

Hello @mimugmail

thanks for the command
installed and found it as service

is there a need of the Hostname?
in my case i define on the Masterside what and where (IP) should come and give a name.

i never hat to add/change a Port Number.

Allowed Network, is this the IP Address of the Munin-Master to add?

maybe it would be usefull to tell over which Ethport it have to make the contact to MuninMaster!

I think it's a good idea to set a hostname manually. Mostly the firewalls are labeled as OPNsense so this would be a good override.

The port has a default of 4949 so this should be fine. Maybe someone wants/needs to change it ..

Allowed networks is munin master, yes.

Currently the plugin only allows you to listen to every interface, usually the service should be blocked by firewall rules so no real security issue.

the a
[Refresh/Reload] Button

would remove old Bridge or VLAN Information
but also add new Bridge or VLAN Information or other stuff to monitor

[mimugmail]

The default is to have all of them currently enabled, correct?
So you are asking just for disable some of them?

[vikozo]

yes @mimugmail
but first would be a reload button to load new VLAN or remove old Bridge information.
But do not missunderstud - i am happy to see how it works and work fine

nice would also be not only to see the igb0, igb1, igb2 but added the "tag" DMZ, LAN, WAN ;-)
nice would also be to get information about updates ;-)

I can promise that this is not possible since DMZ, LAN etc are OPNsense internal descriptions, munin has no chance to get these ...

I will set the plugin to stable with 20.1.3 and then work on your ideas (when time allows).

Thanks for your input!
