Identify current running queries

Hello everyone,

How can I identify a current running queries in couchbase 4.1?
I got help for 4.5 version. And this works great, I simply need to :
“select * from system:active_requests;”

Since we are planning on running 4.1 (until 4.5 comes out), I need to know how in 4.1
Also, how to kill a specific running query in 4.1?
