I am following this tutorial -http://hortonworks.com/hadoop-tutorial/how-to-refine-and-visualize-server-log-data/
Please help me .It is urgent and participated one Innovation contest so I have to implement this.
Hi Burman, I didn't get well your question, in general you should use NiFi only to collect and pre-process all logs (getFile processor can do it). All sort of analyze/transformation of this log should be done in Hive, Pig, Spark, Storm... (for instance), and then you can create a notebook on zeppeling to visualize it. What exactly do you mean with "analyze server log"? how can you get this logs?
