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?
