84. WrocławJUG

After JDD and GeeCON it's time for WrocławJUG!  

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 lines added 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. A tool, which will let you gather, process, analyse logs from many sources: syslog, your application, Apache/ngix, database, firewall, etc. It can alert, search all ways through, analyse the logs no matter what language/technology sent them. And it makes that good. And is Open Source. 

This presentation is about some gotchas based on real-life experience, quick Graylog setup, wiring your apps/systems/servers, analysing logs after. Even if the machine which sent them is already gone. 

This presentation is part two of the logging miniseries. It's assumed that the audience is more or less familiar with the concept of logging, so the introduction in part one (one week before) is recommended if you haven't logged anything so far. 

Some code samples will be in Java, but we'll log stuff not only from JVM: fellow programmers of other languages are invited too.
