#4505 [HHQ-4350] RabbitMQ plugin - CPU Usage continues to collect

[Hyperic Team]

http://jira.hyperic.com/browse/HHQ-4350
RabbitMQ plugin - CPU Usage continues to collect when RabbitMQ Node stopped and unavailable.

After the RabbitMQ server has been added to Hyperic, the CPU Usage shows close to 0% but when the RabbitMQ Node is stopped, CPU Usage jumps to almost 100%. Simply stopping the RabbitMQ Node should not increase the CPU Usage and especialy continue metrics collection.

Trying to reproduce the high CPU Usage, I have seen where the CPU Usage does not show 100% but the problem is still that the metrics continue to collect when the RabbitMQ Node is stopped.

See screenshot 'RabbitMQ CPU Usage.jpg' for visual representation.

Expected Result:


The CPU Usage should remain constant and not collect when RabbitMQ Node stopped

Actual Result:


Stopping the RabbitMQ Node still shows CPU Usage collecting

Steps to Reproduce:


1. Install hq-agent on RabbitMQ platform


2. Log into Hyperic


3. Add RabbitMQ platform to Inventory from Auto-Discovery


4. Select RabbitMQ Node from RabbitMQ platform and configure


5. Allow Availability and Metrics to collect/report


6. Stop the RabbitMQ Node


7. Allow Availability and Metrics to continue collecting/reporting


8. Note the CPU Usage for the RabbitMQ Node continues to collect/report metrics

Additional Information:


Executing top (on the server) when the RabbitMQ Node is stopped shows minimal CPU Usage.
