I know this question has been asked before [here](https://discuss.elastic.co/t/how-to-restart-individual-pipelines/155360) but with no answer.

Is there a way to pass a parameter to logstash to restart only a specific pipeline without impacting the others?

The reason is updated configuration on that specific pipeline.

if you send a sighup to logstash AKA kill -1 PID it will check for configs that have changed and only reload that pipeline a helpful command I use is

#get the process id  
ps aux | grep logstash  
#send sighup and check the log  
kill -1 ID & tail -f /var/log/logstash/logstash-plain.log

this will send the sighup and then open the log file to see if the config loads with no errors
