I am trying out gatling for my project and sending a lot of request within short time, this is my scenario and I got some exceptions at the console. Wondering if that is the expected behavior of gatling when it can’t handle too much request?
Scenario:
setUp(
s1.inject(ramp(100 users) over(60 seconds)).protocolConfig(httpConf),
s2.inject(ramp(100 users) over(60 seconds)).protocolConfig(httpConf),
s3.inject(ramp(100 users) over(60 seconds)).protocolConfig(httpConf),
s4.inject(ramp(100 users) over(60 seconds)).protocolConfig(httpConf),
s5.inject(ramp(100 users) over(60 seconds)).protocolConfig(httpConf),
s6.inject(ramp(100 users) over(60 seconds)).protocolConfig(httpConf),
s7.inject(ramp(100 users) over(60 seconds)).protocolConfig(httpConf),
s8.inject(ramp(100 users) over(60 seconds)).protocolConfig(httpConf),
s9.inject(ramp(100 users) over(60 seconds)).protocolConfig(httpConf),
s10.inject(ramp(100 users) over(60 seconds)).protocolConfig(httpConf),
s11.inject(ramp(100 users) over(60 seconds)).protocolConfig(httpConf),
s12.inject(ramp(100 users) over(60 seconds)).protocolConfig(httpConf),
s13.inject(ramp(100 users) over(60 seconds)).protocolConfig(httpConf),
s14.inject(ramp(100 users) over(60 seconds)).protocolConfig(httpConf),
s15.inject(ramp(100 users) over(60 seconds)).protocolConfig(httpConf),
s16.inject(ramp(100 users) over(60 seconds)).protocolConfig(httpConf),
s17.inject(ramp(100 users) over(60 seconds)).protocolConfig(httpConf),
s18.inject(ramp(100 users) over(60 seconds)).protocolConfig(httpConf),
s19.inject(ramp(100 users) over(60 seconds)).protocolConfig(httpConf),
s20.inject(ramp(100 users) over(60 seconds)).protocolConfig(httpConf)
)
