Hi Ivan,

I think the problem is in the: class-name("org.syslog_ng.elasticsearch.ElasticSearchDestination").

You have installed Elasticsearch version 2.3.3 (seen in: Add path to classpath: /usr/share/elasticsearch/lib/elasticsearch-2.3.3.jar;), and with the above line you say that let syslog-ng use the Elasticsearch version 1 java module.

To use syslog-ng with Elasticsearch version 2 java module the proper class-name would be: class_name("org.syslog_ng.elasticsearch_v2.ElasticSearchDestination")

Or you can configure syslog-ng with the help of scl-s, where you can skip the class-name() option. In this case an example configuration can be the following :

@module mod-java

@include "scl.conf"

elasticsearch2(

index("syslog-ng_${YEAR}.${MONTH}.${DAY}")

type("test")

cluster("syslog-ng")

);

Best regards,

Andras

Im running with Elasticsearch with the following configuration:

java(
    class-path("/usr/lib64/syslog-ng/java-modules/*.jar:/usr/share/elasticsearch/lib/*.jar")
    class-name("org.syslog_ng.elasticsearch.ElasticSearchDestination")
    option("index", "syslog-ng_${YEAR}.${MONTH}.${DAY}")
    option("type", "test")
    option("cluster", "elasticsearch")
#    option("flush_limit", "100")
    option( "message_template", "$(format-json --scope rfc3164 --scope nv-pairs --exclude R_DATE --key ISODATE)\n")
);
};

Any hints on this ?
