Hi i'm new to ELK Stack,
I'm currently trying to ingest data from filebeat to logstash and using grok filter in it.
i accidentally deleted the whole log folder of logstash /var/log/logstash,
so i created the folder by mkdir, but logs didn't show up.
and i removed logstash and reinstalled it. but now i'm getting this error
if i go to /var/log/logstash
and use this command
cat logstash-plain.log |grep ERROR
this is the error i'm getting
java.lang.illegalstateexception: logstash stopped processing because of an error: (systemexit) exit
I'm using RHEL 7 and also
I've set my java path too, Everything is up but logstash is showing me this error.
I've used bin/logstash -f /etc/logstash/conf.d/*conf --config.test_and_exit too check my config file is okay or not and it's result is OK
Any solution would do great,
