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.

• 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 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.
