• This wiki help page assumes that you have used the three system setup procedures to install an Ubuntu server with DSpace software.
• It is assumed that you will be using the same server for monitoring and backup. To setup munin to gather client statistics, follow the procedure below.

Add a firewall rule to allow the server to get the stats:

ufw allow 4949

To install munin, type the following:

apt-get install munin

Add the clients to the /etc/munin/munin.conf file as follows.

Open the file for editing

nano /etc/munin/munin.conf

Add one of the following for each client:

 [%hostname-of-client%]
    use_node_name yes
    address %ip-address-of-client%
