Command Line Options

edit

Filebeat does not have any Filebeat-specific command line options. Instead, you configure the behaviour of Filebeat by specifying options in the configuration file.

The following command line options from libbeat are also available for Filebeat. To use these options, you need to start Filebeat in the foreground.

To start Filebeat, you must use the -c config/path option to specify the path to the configuration file.

$ ./filebeat -h
Usage of ./filebeat:
  -N  Disable actual publishing for testing
  -c string
      Configuration file (default "/etc/filebeat/filebeat.yml")
  -configtest
      Test configuration and exit.
  -cpuprofile string
      Write cpu profile to file
