Logstash not receiving server logs

Hi Am trying to config logstash server for my application server. I am not able to see the logs in the logstash. I need some ones help to check this configuration.

If you provide additional details about your configuration we might be able to help.

Sure .

This is the instruction which i have followed to setup logstash server.

But am not able to see the the logs in Kibana.

Thanks,

/var/log/elasticsearch

in this log i have seen the exception
