Graylog is a great tool for storing your syslog data.
Even better, they provide a virtual appliance to simplify downloading.
Probably the first thing you will want to do is give it a static IP address (as most network devices don't allow you to use a name as a syslog destination).
So first log on to the console and:
vim /etc/network/interfaces
change
iface eth0 inet dhcp
to
iface eth0 inet static
address 10.0.0.41
netmask 255.255.255.0
network 10.0.0.0
broadcast 10.0.0.255
gateway 10.0.0.1
dns-nameservers 10.0.0.1 8.8.8.8
dns-domain acme.com
dns-search acme.com
Using your IP addresses obviously!
exit, and run:
ifdown eth0
ifup eth0
to restart networking with the new settings.
Now you need to tell graylog that things have changed, so just run
sudo graylog-ctl reconfigure
This will go through all the settings and ensure it works with the new IP address
