Grafana vs JMeter

[Sridhar Krishnan]

Hi,

Why Grafana prometheus response time different from JMeter response time.

Eg:
JMeter - 1.4 Sec
Grafana - 1.0 Sec

As per JMeter Glossary:

Elapsed time. JMeter measures the elapsed time from just before sending the request to just after the last response has been received. JMeter does not include the time needed to render the response, nor does JMeter process any client code, for example Javascript.

My expectation is that "prometheus response time" includes only server-side processing time and does not include the time required to establish TCP connection, SSL handshake and the time for the request to travel to the server and back.

So JMeter gives you more or less perceived user experience
