I am pleased to announce that The Logstash Book has been extensively updated to reflect the changes in the Logstash 1.4.0 release. There is a lot of new content, deprecations and updates to reflect the changes in Logstash including new installation methods, changes to the configuration language and a variety of plugins.
It also includes a bunch of updates from awesome folks who have submitted errata and pointed out issues. Please keep this up - it really helps me!
You can find a full list of the changes and updates here.
If you’ve previously bought the book then this update is totally free (if your download link has expired just email me and I’ll renew it).
Please continue to send me feedback, reviews and errata as it is very much appreciated!
