+
+
+Application properties like /etc/collector.properties and Dmaap configuration /etc/DmaapConfig.json are updated frequently by configuration stored in Consul(CBS) http://<kubernetes_host_ip>:30270/ui/#/dc1/kv/<vescollector_SCN> 
+Configuration stored in Consul have bigger priority and always will override local configuration so all configuration modification should be done using Consul update on corresponding kv store. 
+Frequently how often configuration will be fetch from Consul server is manageable in /etc/collector.properties property "collector.dynamic.config.update.frequency={time in minutes}".
+
+Sample configuration of VESCollector K-V store can be found under /dpo/data-formats/ConsulConfig.json
