Hi developers, Ambari deployed Hadoop cluster can be monitored through Ambari REST API. It is possible to use Ambari provided information and Hadoop log files to correlate to gain insights of how Hadoop ecosystem is used.
I did some wireframe design and generated the following dashboard screenshots. The screenshot at 3:54pm is showing the home screen where it displays a list of clusters and over all activities recorded from the clusters. A few key metrics are displaying how many active clusters, and how many users are concurrently using all the clusters. It is sort of a global view of clusters deployed in the world. The second screenshot at 7:21pm is showing individual cluster metrics, and also events happen on the cluster. For example, if someone reconfigured the cluster or alert being generated, there is timeline widget to describe the events. The third screenshot at 7:22pm is showing user activities, where user drill down to applications and search log files generated from both services and applications through solr. I uploaded a sample docker image to docker hub under chukwa/chukwa:latest. Feedback and participation are most welcome. Thank you regards, Eric
