Default Parameters for ZeppParaStatTest

Notes are fundamental elements of a Zeppelin notebook and each instance of Zeppelin has only one notebook which contains many notes. The note can be viewed as a paragraph container. Each note consists of one or more paragraphs of code, which you can use to define and run snippets of code in a flexible manner. Each paragraph consists of 2 sections: code section where you put your source code and result section where you can see the result of the code execution. A paragraph contains code to access services, run jobs, and display results. The user can run all the paragraphs contained in a note sequentially or individual paragraphs can be selected for execution. The status of each paragraph will be shown while executing as READY, FINISHED, ABORT, ERROR, PENDING, and RUNNING. By tracking these status codes, administrator can clearly understand what was exactly happened while executing the paragraphs and can take necessary actions with respect to the respective status. This is where ZeppParaStatTest helps administrators.

This test continuously tracks the status codes of each paragraph that are executed and reports the number of paragraphs grouped under each status. This test also monitors the total number of paragraphs that are executed on the target Apache Zeppelin. The detailed diagnosis of these measures provides the Paragraph ID, progress, start and finish date of paragraphs grouped under each status.

This page depicts the default parameters that need to be configured for the ZeppNotebookTest.

• The TEST PERIOD list box helps the user to decide how often this test needs to be executed.

• To collect metrics from an Apache zeppelin server, the eG agent monitoring the server should be configured to use JMX to connect to the JVM used by the server and pull out the metrics of interest. If JMX requires authentication only (but no security), then ensure that the USER NAME and PASSWORD parameters are configured with the credentials of a user with read-write access to JMX. To know how to create this user, refer to Monitoring Apache Zeppelin. Confirm the password by retyping it in the CONFIRM PASSWORD text box.

• By default, the SSL flag is set to No indicating that the SSL (Secured Socket Layer) is not used to connect to the target Apache Zeppelin. If not so, set the SSL flag to Yes.

• Specify the duration (in seconds) for which this test should wait for a response from the Apache Zeppelin server in the TIMEOUT text box. If there is no response from the server beyond the configured duration, the test will timeout. By default, this is set to 5 seconds.

• Once the necessary values have been provided, clicking on the UPDATE button will register the changes made.

When changing default configurations of tests, the values with “$” indicate variables that will be replaced by the eG system according to the specific server being managed - for instance, $hostName is the host/nickname of the target host, $port is the port number of the server being monitored. E.g., for a server xyz:80, $hostName will be changed automatically by the eG manager to “xyz*” and $port will be changed to “80” when configuring a test.
