Configuration of StormOwnResTest

This test monitors the resources utilized by the users (owners) that includes total number of topologies, executors, workers and tasks completed by the owners in the target Apache Storm. Using this test, administrators would be able to identify the number of used CPU cores, the total memory used by the CPU and the heap/off-heap memory assigned to the owners. Any abnormal condition in the resource usage will alert the administrators to take preventive action against the abnormality.

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

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

• In the HOST text box, specify IP address of the target server that is being monitored.

• In the PORT text box, specify the port number through which the Apache Storm communicates. The default port is 8080.

• By default, the SSL flag is set to No, indicating that the target Apache Storm is not SSL-enabled by default. To enable the test to connect to an SSL-enabled Apache Storm, set the SSL flag to Yes.

• Once the above values are provided, click on the UPDATE button to register the changes made.

When changing the configuration for specific servers, a “*” beside the text box corresponding to the parameter signifies that these values have to be manually configured by the user. The parameter values that require to be configured will typically be prefixed with a “$” or contain a series of “*”. A value of “none” in the parameter value indicates that the corresponding parameter value can be changed if required.
