cpumemd is a simple daemon that listens on a TCP port and responds to two commands:

cpu

mem

When it receives cpu it reports cpu usage as a percentage. When it receives mem it reports memory usage.

There is a client, cpumemtool, that can connect and send either of the above commands, but you could just as easily use netcat too :-)

You will need to have boost C++ libraries installed, and then simply run make. The resulting binaries will be in the bin directory.

This has been tested with g++ 8.1.0 on a reasonably up-to-date (as of 2018-06-09) Archlinux system.

Run the daemon like so:

cpumemd <port>

There are several ways to daemonize it, for example, using nohup, daemonize, systemd, etc.

Run the client like so:

cpumemtool <hostname> <port> <cmd>

Hostname and port should be the hostname and port where cpumemd is running, cmd should be one of cpu or mem. Any other command will just be ignored.
