Munin

Installation

Before installing Munin on fun88体育01 apache2 will need to be installed. The default configuration is fine for running a munin fun88体育. For more information see ???.

First, on fun88体育01 install munin. In a terminal enter:

sudo apt install munin

Now on fun88体育02 install the munin-node package:

sudo apt install munin-node

Configuration

On fun88体育01 edit the /etc/munin/munin.conf adding the IP address for fun88体育02:

## First our "normal" host.
[fun88体育02]
       address 172.18.100.101

Note

Replace fun88体育02 and 172.18.100.101 with the actual hostname and IP address for your fun88体育.

Next, configure munin-node on fun88体育02. Edit /etc/munin/munin-node.conf to allow access by fun88体育01:

allow ^172\.18\.100\.100$

Note

Replace ^172\.18\.100\.100$ with IP address for your munin fun88体育.

Now restart munin-node on fun88体育02 for the changes to take effect:

sudo systemctl restart munin-node.service

Finally, in a browser go to https://fun88体育01/munin, and you should see links to nice graphs displaying information from the standard munin-plugins for disk, network, processes, and system.

Note

Since this is a new install it may take some time for the graphs to display anything useful.

Additional Plugins

The munin-plugins-extra package contains performance checks additional services such as DNS, DHCP, Samba, etc. To install the package, from a terminal enter:

sudo apt install munin-plugins-extra

Be sure to install the package on both the fun88体育 and node machines.
