Instead we should read fixture with example of expected line to process and then apply filter. Filters should not deal with input and output logstash statements. Define your filter_spec.rb inside spec/filters folder. Lets assume you want to regex line like username=. Now we are ready to define actual spec to test our logstash filter. join ( ROOT_PATH, '.', 'conf.d/' ) def load_fixture ( filename, settings = to replace variables on deploy by using ansible. expand_path ( _FILE_ )) TEMPLATES_PATH = File. expand_path ( "./", _FILE_ ) end module Helpers ROOT_PATH = File. Build failure is due to an open dependency on logstash-devutils Im.
LOGSTASH DEVUTILS UPDATE
const_defined? ( :LOGSTASH_HOME ) LogStash :: Environment :: LOGSTASH_HOME = File. logstash-plugins/logstash-input-tcp: Update log4j, make runtime rely only on. Require "logstash/devutils/rspec/spec_helper" require 'rspec' require 'rspec/expectations' require 'ostruct' require 'erb' require 'yaml' require 'json' # running the grok code outside a logstash package means # LOGSTASH_HOME will not be defined, so let's set it here # before requiring the grok filter # coming from the original examples for logtash specs. Lets start from the Dockerfile and then I will extend step by step the project structure. The plugin is designed to produce raw data, but the indexing should handle each field separately.
LOGSTASH DEVUTILS INSTALL
I had a lot of experience in Ruby On Rails development the last years and decided to cover Logstash filters by RSpec test cases to save my time, because logstash is using jruby inside of their packages and gems to distribute the extensions.Īlso it would be great to have everything in docker to skip Logstash and gem installations on local machine. It can be installed using the standard Logtstash plugin installation procedure: bin/logstash-plugin install logstash-input-reddit-0.1.0.gem Downstream processing One huge benefit of Logstash is the power of its processing pipeline. While I was working on processing the events coming to Logstash I found that it's pretty annoying to work on filter changes if you have complex regular expressions, structures or conditions.
