How to run from command line:

1- In case of GET endpoint without required body:

vegeta attack -targets=targets.txt -rate=10 -duration=10s | vegeta report

2- In case of POST endpoint and i need body:

Create body.json file and include it in targets.txt AND make sure that lines order matters

FIRST the endpoint THEN the headers THEN the body.json path (complete path) WITHOUT SPACES IN BETWEEN

vegeta attack -targets=targets.txt -rate=10 -duration=30s | vegeta report

3- To save report result in text file you can run the command as follow:

vegeta attack -targets=targets.txt -rate=10 -duration=5s | vegeta report > anas.bin

4- To generate different report you can run the command as follow:

vegeta attack -targets=targets.txt -rate=10 -duration=5s | vegeta report -reporter=json

5- To just dump vegeta report as a raw data

vegeta attack -targets=targets.txt -rate=10 -duration=5s | vegeta dump

6- To use vegeta with jplot and jagger

vegeta attack -targets=targets.txt -rate=20 -duration=15m | vegeta dump | \
     jaggr @count=rps \
           hist\[200,300,301,400,404,500,502,503\]:code \
           p30,p50,p85:latency \
           sum:bytes_in \
           sum:bytes_out | \
     jplot rps+code.hist.200+code.hist.300+code.hist.301+code.hist.400+code.hist.404+code.hist.500+code.hist.502+code.hist.503 \
           latency.p85+latency.p50+latency.p30 \
           bytes_in.sum+bytes_out.sum

OR => can be on oneline

vegeta attack -targets=targets.txt -rate=20 -duration=15m | vegeta dump | jaggr @count=rps hist\[200,300,301,400,404,500,502,503\]:code p30,p50,p85:latency sum:bytes_in sum:bytes_out | jplot rps+code.hist.200+code.hist.400+code.hist.404+code.hist.500+code.hist.502+code.hist.503 latency.p85+latency.p50+latency.p30 bytes_in.sum+bytes_out.sum
