Logstash central log server with redis, elasticsearch and kibana

As a Linux system administrator we see a lot of logs daily. Whenever we a get problem, first thing we will check will be for the corresponding application/system logs. Its fine when we have a couple of servers and applications. What if we have 10s of servers and many applications on them? Then its better to have a centralized log server. A central syslog server?

Well with a central syslog server you get all the logs in a single server. But how you will keep track of logs? or how you will check for a particular log? You will grep or  awk? Its time consuming and not easy.

Ubuntu 15.04 named as Vivid Vervet

Ubuntu is one of the most popular Linux distributions. I personally use Ubuntu 14.04 with my Dell Inspiron Laptop. I changed from Windows Vista to Ubuntu long back. So far so good. I get most of the things done with Ubuntu (without restarting). And you will get a lot of help online. From community and open source forums. Isn't cool?
