Hi there, I have 2 simple questions regarding logstash pipelines: 1. Is it possible in a pipeline - if I made a change and need this change a filter e.g. to take effect - to restart only this single pipeline.id? Or can I only make a systemctl restart for the whole logstash process? Or would the automatic restart of logstash only restart this one portion? 2. Is it possible to define a max cpu-quotas for each pipeline? or generally? Thanks Stefano ---
