Installation

Install required dependencies:

sudo dnf -y install gcc python python-pandas qpid-proton-c-devel sysstat

Install Qbench itself. The resulting executable is at ~/.local/bin/qbench.

cd qbench
./plano install

Building against locally installed libraries

To alter the GCC library and header search paths, use the LIBRARY_PATH, C_INCLUDE_PATH, andCPLUS_INCLUDE_PATH environment variables.

export LIBRARY_PATH=~/.local/lib64
export C_INCLUDE_PATH=~/.local/include
./plano clean,install

Commands and options

qbench run

usage: qbench run [-h] [--connections COUNT]
                  [--duration SECONDS] [--rate RATE]
                  [--body-size BYTES] [--output DIR]

Run the benchmark (client and server)

options:
  -h, --help           Show this help message and exit
  --connections COUNT  The number of concurrent client
                       connections (the default is a set of 1,
