We are reposting all the alerts to message bus with different subject through nas AO.We have created a attach queue to get those posted messages and have a java based custom probe to subscribe the attach queue to process the messages. Issue is 20-30% of the alerts are missing in custom probe log file. Nas log shows the alerts are posted successfully. We are not able to track if the messages are picked by queue or not. Is there any way to check if our messages went into queue. we are not sure if queue is not processing those messages or custom probe is skipping them.
