Running logstash in the background in production environment


(Mulligan) #1

Hi,

I think i am having difficulty on starting logstash as a service which runs continuously in the background to read all the config files under the directory /etc/logstash/conf.d/

Although when i run it like /usr/share/logstash/bin/logstash -f /etc/logstash/conf.d/first.conf , it works fine and does what is written in the config file. But in the production environment, the service has to continously run and keep loading the files present in /etc/logstash/confd./

/usr/share/logstash/bin/logstash -f /etc/logstash/conf.d/first.conf &

Or am I misunderstanding your question? Try adding the &

This is fine as long as i am loading first.conf file, but in the real scenario the input would be a beat plugin listening on port 5044, for that logstash service should be continuously running.

How do i make logstash running continously and loads multiple config files that i have in /etc/logstash/conf.d

When i run logstash like this

/usr/share/logstash/bin/logstash --path.settings /etc/logstash/conf.d -f /etc/logstash/conf.d/app.conf & it works forever, but not when i run this systemctl start logstash

No errors logged in /var/log/logstash.log
