Introduction
- 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
To enable Munin on the Apache2 web server, type the following
Please note: This is only when using Ubuntu 14.04 and higher.
a2enconf munin
service apache2 restart
Add the clients to the /etc/munin/munin.conf file as follows.
- Open the file for editing
sudo mcedit /etc/munin/munin.conf
- Add one of the following for each client to be monitored:
[%hostname-of-client%]
use_node_name yes
address %ip-address-of-client%
