+# PNDA Zero Touch Telemetry
+
+## Overview
+
+The Zero Touch Telemetry application is a configurable telemetry-to-OpenTSDB solution. Metadata
+files are used to configure the ZTT application for each telemetry source.
+
+The application receives telemetry events from Kafka, transforms the contents into a set of
+timeseries datapoints and writes them to OpenTSDB.
+
+This application demonstrates ingest of VES events from a virtual firewall into PNDA. The
+extracted metrics get stored in HDFS and the timeseries database. This enables direct
+visualization via Grafana as well as downstream Spark based analytics.
