```auto
filebeat.inputs:
# Each - is an input. Most options can be set at the input level, so
# you can use different inputs for various configurations.
# Below are the input specific configurations.
- type: log
# Change to true to enable this input configuration.
enabled: true
# Paths that should be crawled and fetched. Glob based paths.
paths:
- {some path}
fields:
target_index: import-export-logger
build_version: $build_version
```
Here I want to add **build\_version** in the fields. My build\_version is stored in a file on each server.
Can filebeat read the file and add build\_version in the field?
