File Output

edit

The File output dumps the transactions into a file where each transaction is in a JSON format. Currently, this output is used for testing, but it can be used as input for Logstash.

output.file:
  path: "/tmp/metricbeat"
  filename: metricbeat
  #rotate_every_kb: 10000
  #number_of_files: 7

File Output Options

You can specify the following options in the file section of the metricbeat.yml config file:

enabled

The enabled config is a boolean setting to enable or disable the output. If set to false, the output is disabled.

The default value is true.
