Hi,

The kill -SIGHUP command is used to reload the configuration in some applications, but in the case of Logstash, this is not the correct way to reload the configuration.

If you want to manually reload the configuration, you can send a SIGHUP signal to the Logstash process, but this requires the --config.reload.automatic option to be enabled.

bin/logstash --config.reload.automatic

Just to add that this only works when you run Logstash from the command line, if Logstash is running as a service, which is way more common, this setting needs to be added to logstash.yml and the service needs to be restarted once.

config.reload.automatic: true
