Trying out logstash for the first time, but I'm getting this error on a very basic localhost:5044 to S3 configuration:

My logstash config:

# /etc/logstash/conf.d$ cat vf-settings.conf

input {
  beats {
    port => 5044
  }
}

output {
  s3 {
    region => "ap-southeast-1"
    bucket => "vf-logstash"
    size_file => 20000
  }
}

All my other configs are untouched.

Logstash worked when I tried the following command. My logs appeared in my S3 bucket.

sudo /usr/share/logstash/bin/logstash -f '/etc/logstash/conf.d/vf-settings.conf'

Any ideas why running logstash through the service + config file doesn't work?

input {
  beats {
    port => 5044
  }
}

output {
  stdout { }
}

Does the above work as a service? If not then it might be permissions based. What user:group owns vf-settings.conf?

Hi, that config works. Switching back to my original config after trying that fails again.

root owns it:

-rw-r--r-- 1 root root 254 Aug 19 02:37 vf-settings.conf

Can you explain what you mean when you say you run it as a service?

5

Just running logstash with systemctl: sudo systemctl start logstash.service, instead of running the executable in the bin folder

Decided to boot up a new EC2 to try set up everything all over again. It worked.

Not sure what might be the difference. I suspect the error might be because I installed Logstash before installing Java. I did see some strange messages when I did that.

Either way, it works now.
