I'm exploring logstash to solve some of our logging-related problems but ran into a weird issue:
I installed logstash onto Ubuntu 16.04.2 LTS via APT (https://www.elastic.co/guide/en/logstash/2.3/installing-logstash.html), installation was successful.
Then I tried to run it with bin/logstash --log.level debug --config.debug
No output in terminal, /var/log/logstash is empty
I thought I'm having an environment issue, tried logstash image from dockerhub (https://hub.docker.com/_/logstash/), ran it with -it flag, again no output in terminal
Realized that dockerhub image is deprecated, tried docker.elastic.co/logstash/logstash:5.2.2
a) ran it with -it flag, no output in terminal
b) ran it with -d flag: docker logs is empty. Logged into container, could not find any logs (evidence that logstash started) in /var/log/ neither in /usr/share/logstash/
What am I doing wrong?
Thanks in advance!
