not able to run prom bench

[saifjunaid]

I have prometheus binary in the same folder

sudo ./prombench -rmtestdir -exporters inc:20 -- ./prometheus --log.level=info I am getting error "Prometheus returned exit status 1" if i do sudo strace -f -o log.tr ./prombench --rmtestdir --exporters inc:20 -- ./prometheus

The error is what i see is "Error parsing commandline argument" in log.tr

/prometheus --version prometheus, version 2.7.0 (branch: HEAD, revision: 410ee9e04acb8f59f400858752ca82b4ef88035e) build user: root@3bc81b516055 build date: 20190128-10:09:51 go version: go1.11.5
