================================================================================
In order to start transforming logs to metrics, following configuration bits
needs to be established:

1) zookeeper nodes addresses
2) kafka brokers addresses
3) name of the topic, monasca-log-transformer sends logs to
4) name of the topic, metrics are sent to from monasca-api

Copy sample file to the correct location and make your changes:

1) cp %{mlm_cfg_dir}/%{sname}.conf.sample %{mlm_cfg_dir}/%{sname}.conf
2) vi %{mlm_cfg_dir}/%{sname}.conf
