etcd/tools/benchmark
is the official benchmarking tool for etcd clusters.
Install the tool by running the following command from the etcd source directory.
$ go install -v ./tools/benchmark
The installation will place executables in the $GOPATH/bin. If $GOPATH environment variable is not set, the tool will be installed into the $HOME/go/bin. You can also find out the installed location by running the following command from the etcd source directory. Make sure that $PATH is set accordingly in your environment.
$ go list -f "{{.Target}}" ./tools/benchmark
Alternatively, instead of installing the tool, you can use it by simply running the following command from the etcd source directory.
$ go run ./tools/benchmark
The following command should output the usage per the latest development.
$ benchmark --help
