Questions About Cacti's Queue Graphing

Hi guys, this is my first post so I apologize if I’m posting in the wrong sub-forum.

I have a Cacti and several few routers integrated with it, which are running well for years. I haven’t found an issue about graphing queue, until now.

I have one router which used to successfully creating/graphing simple queues, but one day it won’t let me to create any simpe queue graphs. My data template for simple queue is |host_description| - Simple Traffic - |query_qsName|. This Router only translate the |host_description|, but the |query_qsName| isn’t. So when I create new simple queue graph, it only shows the message of “Created graph: RO-Dist-A - Traffic - |query_qsName|”. RO-Dist-A is my host name.

Strange thing is, when I tried to create a Queue Tree, using the same template was successful,-The router was able to translate |query_qsName|. This is the example Created graph: RO-Dist-A - Queue Tree Traffic K-Link-Up (no-mark)

I think the problem must be in the Router, because using the same template I’m able to create/graph simple queue from another Router. And yet I can’t seem to find what’s wrong. Any help would be greatly appreciated.

Thank you.
