Elastic Stack Logstash

Hi,
I need to get data from a PostgreSQL DB and index it into Elasticsearch. When I run /opt/logstash-2.3.3/bin/logstash -f contacts-index-logstash.conf I receive the following error:

Could not find log4j2 configuration at path /elk/logstash/config/log4j2.properties. Using default config which logs to console

You need to specify full path to driver:
Example: jdbc_driver_library => "/usr/local/src/elk/postgresql-9.4-1212.jre6.jar"
Because in your case, JDBC plugin is trying to find driver in /elk folder in root
