Hello Yodying,
I hope you are doing good !
Your support case is (SR # 71762595), so please use this as your future reference point.
As I understand from the case notes, you have reported that, you need Cacti template on version 10.5.
As cacti is open you have to create template on your own. I can only provide you the OID's for Netscaler 10.5 or 11.0 Netscaler.
You can also download the SNMP OID's from the downloads option , present right under logout butoon in Netscaler GUI.
Kindly let me know if you have any query !
I wish you a nice day ahead !
