Hi Team,

I have a setup of syslog-ng in Centos 7 with jdk 1.8.To use a custom java program i have installed syslog-ng-java plugin using yum install. I have added a custom syslog-ng file in conf.d directory.On starting the syslog-ng service i am reciving error destination java plugin not found.

ERROR:

Jun 24 14:16:01 localhost syslog-ng: Error parsing destination, destination plugin java not found in /etc/syslog-ng/conf.d/syslog-ng-custom.conf at line 15, column 3:
Jun 24 14:16:01 localhost syslog-ng: included from /etc/syslog-ng/syslog-ng.conf line 68, column 1

Jun 24 14:16:01 localhost syslog-ng: ^^^^

Syslog-ng is detecting the java plugin(verified by syslog-ng -V)

};

Can someone please tell me what i am missing?
