Measures reported by ZeppNotebookTest

Apache Zeppelin is an open web-based notebook that enables interactive data analytics and collaborative documents with SQL, Scala, Python, R and more. It brings data ingestion, data exploration, visualization, sharing and collaboration features to Hadoop and Spark. Apache Zeppelin interpreter concept allows any language/data-processing-backend to be plugged into Zeppelin. Zeppelin currently supports many interpreters such as Apache Spark, Python, JDBC, Markdown and Shell. Also, Apache Zeppelin provides built-in Apache Spark integration.

A Zeppelin notebook is a browser-based GUI for interactive data exploration, modeling, and visualization. As a notebook author or collaborator, you write code in a browser window. When you run the code from the browser, Zeppelin sends the code to backend processors such as Spark. The processor or service returns results; you can then use Zeppelin to review and visualize results in the browser. Apache Zeppelin has a pluggable notebook storage mechanism controlled by zeppelin.notebook.storage configuration option with multiple implementations.

Notes are fundamental elements of a Zeppelin notebook and each instance of Zeppelin has only one notebook which contains many notes. The user can create, import or delete notes which will be stored by default in the Zeppelin home notebook folder. Zeppelin is considered to be a Big Data tool which support multi-user capability. Thus, it is difficult to keep track on the number of notebooks created or deleted from Zeppelin. For this eG enterprise offers ZeppNotebookTest. This test reports the number of notebooks currently stored in the Zeppelin notebook folder and detailed diagnosis of this measure provides the name and ID of all the notebooks present in Zeppelin. This metric helps administrators to figure out the details of notebooks that are currently present in Zeppelin.
