Re: RabbitMQ monitoring extension error

Hi,

 

I am copying response from extension SME from internal request , see if below helps, if not based on your response we will involve extension SMEs, keep us posted, as we see host:port is missing in error URL only URI found:

"Your endpoint is not returning any data for the extension to process. Please verify whether you're using the right URL. Also, provide us with the o/p of 
curl -kv http://<host:port>/api/federation-links"

Hi Barry,

 

Have you enabled federation plugin in RabbitMQ? if not, please take a look at https://www.rabbitmq.com/federation.html.  Please file a help ticket in Zendesk with debug logs for faster resolution of the issue.

 

 

Thanks,

Re: RabbitMQ monitoring extension error

Hi Barry,

 

The following error is because you don't have the federation plugin installed on RabbitMQ instance.

[Monitor-Task-Thread2] 21 Jun 2017 14:10:55,135 DEBUG RabbitMQMonitorTask - Error while fetching the '/api/federation-links' data, returning NULL

 

 

Please refer here for more details (http://www.rabbitmq.com/federation.html).

 

In case of further issues, we suggest you to raise a heldesk ticket at help@appdynamics.com with all the configuration and log files.

 

Thanks
