JMeter summariser report

["Bhadauria, Tarun Kumar" <ta...@zalando.de>]

Hi there,

I have idea of jmeter summariser report but don't fully understand it.
My jmeter instance has summariser.interval set to 30 sec and this is what
see on terminal.

summary +      7 in  17.1s =    0.4/s Avg:  2057 Min:   228 Max:  6293 Err:
    0 (0.00%) Active: 1 Started: 1 Finished: 0
summary +      8 in  27.4s =    0.3/s Avg:  2994 Min:   622 Max:  6746 Err:
    0 (0.00%) Active: 1 Started: 1 Finished: 0
summary =     15 in    45s =    0.3/s Avg:  2556 Min:   228 Max:  6746 Err:
    0 (0.00%)

These are few things I can not comprehend -

1. Despite interval is set to 30 secs why is summary reported on 17.1, 27.4
and 45s ?

2. What are - "7 in  17.1s =    0.4/s", "8 in  27.4s =    0.3/s" etc in
summariser report?

Thanks
