mmbwmon

Main Memory Bandwidth Monitor

Mmbwmon is an agent that provides an estimate on the main memory bandwidth used on a system. Communication between the agent and other applications is based on MQTT with YAML messages. Take a look at the fast-lib if you are looking for a C++ library to communicate with mmbwmon.

Requirements

The source code in this repository is essential self contained and all unusual dependencies are automatically build when compiling mmbowmon. Nonetheless, you require:

• A compiler supporting C++14
• CMake (version >= 3.1)

If you wand to use mmbwmon to stop/restart cgroups (on by default), you also need:

• cgroupfs mounted at /sys/fs/cgroup (mount -t cgroup cgroup /sys/fs/cgroup/).

Setup

To use mmbwmon you must:

1. compile mmbwmon as every other CMake based project. Just make sure to use the correct compiler (i.e. by calling CC=clang CXX=clang++ cmake ..). If you want to disable cgroup support use ... cmake -DBUILD_CGROUP_SUPPORT=FALSE ..
2. run ./mmbwmon --help and read the available options.
3. run ./mmbwmon with the options matching your hardware and MQTT configuration.
