In this demo, we present a monitoring platform dedicated to the collection, storage, analysis and visualization of logs and network flow data of mobile applications. The platform relies on a set of on-device probes to monitor network and system activities of these applications. The data are collected from these probes and parsed through generic and flexible collectors relying on Flume agents that we have adapted and extended. We are storing the collected data using a column oriented Hbase storage engine which is the Hadoop database. Finally, after being parsed, the data are made available within the Elasticsearch engine to search and visualize them using the Kibana tool.
