How do I add AWS metadata to Filebeat?

I want to include AWS Instance's tag information in each Filebeat document. I can think of two ways to do this -

  1. Modify the log output and include the info in there. This will require tweaking all the services whose log files are being tracked.
  2. Run a script at launch that
  • modifies the filebeat.yml file
  • pulls AWS metadata for that instance
  • and adds the tag info to yml file

It sounds like method 2 is the right approach.
Is there a better way to do this? Does Filebeat provide a way to dynamically set prospector attributes?

You can also use environment variables. See here for more infos.

You just need to add this to your config file if you want instance_id. For other information you could use environment variables.

See the add_cloud_metadata documentation for more details.

Thanks. This helps.
