I have now played on packetbeat for a couple of weekds and everything was fine until I add new http ports on my packetbeat.yml configuration file. Since then, some events have been sent to the elasticsearch cluster with negative value for the responsetime field
Just to let you know, I am working with packetbeat and elasticsearch in docker containers. The WS is a spring boot application, deployed directly at the host level (no container).
The throughput is not so much : 1 call per second.
