Simple Java Program for publishing Syslog Events

In the Using Syslog as source in Flume i blogged about how to configure flume to listen for Syslog event on particular UDP port. I wanted to test that configuration so i built this simple java program that can publish Syslog event on given host and port no. You can download the source code for this project from GitHub This program takes 3 arguments first is hostname for the syslog server, second is the port on which the server is listening and third is the actual message that you want to send.

Using Syslog as source in Flume

I wanted to figure out how to use Flume for receiving Syslog message. So i tried 2 different configurations one is using Syslog server on TCP port and other on UDP port. This is the flume configuration for listening on UDP port Copy the flumesyslogudp.properties file in the conf directory of your flume server and use following command to start flume server

bin/flume-ng agent --conf conf --conf-file conf/flumesyslogudp.properties --name agent1 
-Dflume.root.logger=DEBUG,console

Or you can configure flume to listen on TCP port. Only difference is the source type is syslogtcp instead of syslogudp

bin/flume-ng agent --conf conf --conf-file conf/flumesyslogtcp.properties --name agent1 
-Dflume.root.logger=DEBUG,console
