After we did an manual injection into a test JSP page, we keep getting the following critical error message

AGENT_ASYNC_ADD_REG_LIMIT_REACHED

Async ADD registration max limit of 500 reached

Where has it gone wrong ?

Hi,

Thanks for writing in appsphere community forum. please find our response below:

This isssue is not related to enabling manual EUM injection, can you check whether there is any new BT registered after manual injection and that makes async calls, as EUM injection is based on js injection and should not increase any async calls, we suspect there might some activity in your application that is making async calls, let us know if any disconnect

regarding error message:
- There is a default limit of 500 async calls can get registered in a min. If it exceeds that limit you come across such issues.

- In the newer controller version these notifications are added to the controller as Event notifications. Basically these events are added to improve the performance of controller and limit agent overheads. Once the internal limits are reached, the notification events are shown on controller GUI as seen in your screenshot. By default, it is limited to 500 per agent.

- We can tackle such scenarios by increasing the Async ADDs limits setting node level property 'max-async-task-registrations-allowed'. Before suggesting node level properties involved, we would like to warn you that we do not recommend editing these values as this might add to overhead. Please be cautious before editing them to a high value. Please find node level property to increase the limit:
- AGENT_ASYNC_ADD_REG_LIMIT_REACHED : Please set agent property max-async-task-registrations-allowed where default limit is 500.

Since this property is a unlisted node property, it must be added as a new agent property.
Please have reference documentation link to register that node property below:
http://docs.appdynamics.com/display/PRO12S/App+Agent+Node+Properties#AppAgentNodeProperties-Toregist...

You can also delete that event by selecting the event and selecting delete option in event popup as referred in screenshot.


Hope this answers your question. Do write back for further queries.

Thanks,

Arun
