Graylog is an open source log collector that allows you to centralise you logs in an easy to use manageable interface. With a wide range of adapters available it can receive logs from pretty much anything that you can possibly think of.

I'm going to introduce you through the basics of what Graylog can do for your project and how to get your log messages posting to it using Monolog. But what if you have an old legacy project that just logs to file and would be a nightmare to try modify! Well I have a solution for that, I'm also going to also show you how to set up using the Filebeat from elastic.

Filebeat is a lightweight data shipper that is easy to set up and can very easily push any logs files your application may generate to Graylog (or any log manager that can utilise the Lumberjack message specification)
