thx for your idea tudor, but how can i do a URL(and URI) monitoring with metricbeat?
No module seems to handle this feature..
Edit : my mistake: i looked at metricbeat and not http metricbeat
Edit 2 : same issue : https://www.elastic.co/guide/en/beats/metricbeat/master/metricbeat-metricset-http-json.html#_response_enabled
=> cant get response body to stock it as field
