This article will help you diagnose issues with your https://logit.io/sources/configure/filebeat configuration file. First you are going to check that you have set the inputs for Filebeat to collect data from.
This means that you are not using a module and are instead specifying inputs in the filebeat.inputs section of the configuration file.
When specifying paths manually you need to set the input configuration to enabled: true in the Filebeat configuration file.
While it may seem simple it can often be over-looked, have you set-up the output in the Filebeat configuration file correctly?
