Let me start this entry with a dad joke. An electron rides a motorcycle. Suddenly, a police officer stops the electron and says: ‘I had to stop you, because you were speeding, driving exactly 178 and half kilometres per hour.’ ‘Well, THANK YOU VERY MUCH, officer!’ the electron says, ‘Now I have absolutely no idea where I am!!!’ Some dad jokes are terrible, and don’t worry if you don’t get this one.
There are 10 kinds of people: the ones who already log stuff and the ones who will. ;-) But what can be fascinating about logging? It’s just adding some statements of given level to a file in /var/log, so what’s this presentation for in the fist place? Well, ordinary adding lines to /var/log and tracing them with tail -f or searching with grep is so… 1980 and inefficient. Meet Graylog: a centralised and distributed log management system.
