Simply install Graylog under Ubuntu Server

Graylog is an open source log management and data analytics. It's a 'Splunk' like but for free and open source, useful for collecting your syslog messages for example.

Here is a little script provided by mrlesmithjr on github to simply install Graylog on your server (and it works great) :

$ sudo apt-get -y install git
$ cd ~
$ git clone https://github.com/mrlesmithjr/graylog2/
$ chmod +x ./graylog2/install_graylog2_20_ubuntu.sh
$ sudo ./graylog2/install_graylog2_20_ubuntu.sh
