Munin | Group Information

Created: 17 October 2019 | Written by vincent | Print | Email | Hits: 4389

Munin | Group Information

How to use and where to define Groups, and the difference in using the Munin-Master <--> Munin-Node vs. Munin-Master with SNMP

Munin-Master <--> Munin-Node

in the Munin-Master device in the file

# /etc/munin/munin.conf

you have information like this to add for each Munin-Node

[munin-node.yourDomani.org]
address 10.10.10.10
use_node_name yes

With this ([munin-node.yourDomani.org]) part you are able to define some structure for your device.
The first part, bevor the dot, is your device you wish to monitore, behinde the dot you build your structure.

If you wish to Group it and split your VM, Switch, Hardware, Infrastructure device you could create a structure like this

[server1.HW]
[Munin.VM]
[debian9.VM-Test]

Munin-Master <--> SNMP-"Node"

in the Munin-Master device in the file

# /etc/munin/munin.conf

you have information like this to add for each

[munin-node.yourDomani.org]
address 10.10.10.10
use_node_name yes

Munin-Node unter FreeBSD / FreeNAS

Created: 07 January 2017 | Written by vincent | Print | Email | Hits: 8598

Monitoring FreeBSD with Munin

Munin is a monitoring tool available in the FreeBSD ports. It tracks the vital signs of your servers and charts everything on graphs by day, week, month and year. It makes it easy to see when your server gets spikes of traffic and how well it handles them. It can also show you how your traffic is increasing over the month or year so that you can plan out when you will need to upgrade or add more servers. Add a comment
