Munin : Add Monitoring Target Hosts2026/04/06

 

It's possible to monitor other hosts.
For example, configure a host named [node01.srv.world] as a monitoring target.

[1] Install [munin-node] on a new monitoring target.
# install from EPEL

[root@node01 ~]#
dnf --enablerepo=epel -y install munin-node
[root@node01 ~]#
vi /etc/munin/munin-node.conf
# line 38 : change to your hostname
host_name node01.srv.world

# line 47 : add permission to connect for monitoring ( specify Munin server )
allow ^127\.0\.0\.1$
allow ^::1$
allow ^10\.0\.0\.30$

[root@node01 ~]#
systemctl enable --now munin-node
[2] If Firewalld is running, allow service port.
[root@node01 ~]#
firewall-cmd --add-port=4949/tcp

success
[root@node01 ~]#
firewall-cmd --runtime-to-permanent

success
[3] Configure Munin server to set new target host.
[root@dlp ~]#
vi /etc/munin/munin-conf.d/nodes.conf
# create new
[node01.srv.world]
    address 10.0.0.51
    use_node_name yes

[root@dlp ~]#
systemctl restart munin
[4] Login to the Munin admin site and make sure a new taget host is displayed after few minutes later.
