Hey, im using elastic,kibana,logstash, metricbeat and i want to add to EVERY document i get from metricbeat, a field that will be set by making an api call from server and fetching data. from my searches, i see i can set static fields and values, by using the add\_fields processor, or the fields in the metricbeat.yml but i dont want static value, i want to add to every document a field like "timestamp" that his data will come from api call? how should i achieve this? thank you. ---

Hey @benedery, welcome to discuss 🙂 I don't think this is possible with metricbeat, but have you tried with the [http filter plugin](https://github.com/logstash-plugins/logstash-filter-http) for Logstash? ---
