filebeat

At the moment, if a fileset is configured multiple times, Filebeat makes unnecessary requests to Elasticsearch. When an Ingest pipeline is loaded, first Filebeat checks if a pipeline with the given ID exists and if not it loads the pipeline. Unless overwrite is forced, then there is no extra check, just loading: https://github.com/elastic/beats/blob/master/filebeat/fileset/pipelines.go#L115-L135

Feature idea, add beat info metrics from the stats endpoint /

{
  "beat": "pubsubbeat",
  "hostname": "pubsub-sidekiq-inf-gstg",
  "name": "pubsub-sidekiq-inf-gstg",
  "uuid": "FOO",
  "version": "7.5.1"
}

Would make a metrics like this:

pubsubbeat_build_info{version="7.5.1"} 1
pubsubbeat_beat_info{beat_name="pubsub-sidekiq-inf-gstg",uuid="FOO",} 1
