Hello,

I installed logstash as per documentation and service started successfully. But, when we trying telnet localhost 5044, it is not working and the netstat also showing nothing. Can you please suggest me how to fix it. I double checked none of iptables and selinux running.

[root@logstash ~]# /opt/logstash/bin/logstash -f /etc/logstash/conf.d/first\_pipe.conf --configtest  
Configuration OK

[root@logstash ~]# netstat -antp

[root@logstash ~]# telnet logstash 5044

your netstat does not show it is listening on port 5044, did you run the command without the configtest? also can you provide your config file. is there anything in the log file or output when running the command?

Have you run `ps auwwx | grep java | grep logstash` to see if Logstash is actually running?

I have noticed when my logstash is running but netstat shows it is not listening that there is an issue with the logstash filter. Can you provide first\_pipe.conf with any sensitive information taken out?
