Hi Yodying,
I have been searching information relevant to your request.
Netscaler support list of OID, You can check in the below link
http://support.citrix.com/article/CTX137665
I think packet per sec can be achieved by using
vsvrTotalPktsSent (1.3.6.1.4.1.5951.4.1.3.1.1.35)
vsvrTotalSynsRecvd (1.3.6.1.4.1.5951.4.1.3.1.1.36)
However I am not sure how we can achieve other request.
There are no specific OID for your request.
If you can manipulate the extracted snmp value in cacti, it may possible to achieve what you want.
So far, this is all information I can provide.
If you have question please let me know.
I will keep looking if there is more information I can provide.
