I want to measure the performance of certain key transactions of our system based on couchbase 4.x version. I use the following Jmeter transactions to create the traffic on syncgw - Login (POST), fetch entity (GET), subscribe entity (GET) etc. So a) how do I translate/measure ops/sec based on these transactions and b) how do I measure the doc size being retrieved or sent to couchbase during these transactions? I am a novice user to couchbase testing. Any suggestion would help.
