Daemon to monitor runtime of processes and to terminate related processes when limits exceed (Games - Do you know that? Your son is trying to play all day long...)

ZockZilla

Daemon to monitor runtime of processes. When limits get exceeded, processes and matching child processes will be terminated. They are terminated again when they are restarted in the configured amount of time.

Collected information can be written into InfluxDB via cpprestsdk to be able to use Grafana to create nice dashboards and to send notification e.g.

ToDo

• Port of the system interaction for Windows. In general, the system interactions are cleanly separated from the business logic by interfaces, but there is no time to implement it right now.

Configure

It's possible to configure processes to be observed and their limits and implications. Observed processes can be matched with whitelist and blacklist patterns. See some defaults as an example here: gsc.config.xml

vim /usr/share/gsc/gsc.config.xml
...

Enable and run the daemon

sudo systemctl --system daemon-reload
sudo systemctl enable gsc
sudo systemctl start gsc

Build it locally

When the prebuild debian package is not sufficiant only.

Requirements

• c++14 enabled compiler
• cmake (>= 3.1.2)
• log4cxx (>= 0.10.0, there is no conan package)
• python3 as a requirement for conan
• conan package manager (See: https://docs.conan.io/en/latest/installation.html)

(boost, cpprestsdk, gtest gets installed via conan)

apt-get -y install gcc cmake make liblog4cxx-dev python3-pip python3-setuptools python3-wheel ... maybe something more
pip3 install conan

Build Instructions

mkdir build
pushd build

# Install dependencies
#
conan install --build missing ../
#
# OR maybe when you get linker errors and you are using gcc
conan install --build=missing ../ -s compiler.libcxx=libstdc++11

# Build lib, executable and tests
#
cmake -DCMAKE_BUILD_TYPE=Release ../source
cmake --build . --config Release -- -j

# Run tests
#
bin/gsclib.test

popd

Create a package for Debian like systems, check and install it

pushd build

cpack
dpkg --contents gsc*.deb

# Install package when satisfied
#
sudo dpkg -i gsc*.deb

popd

zock-zilla's Issues

Port system interaction to windows and provide installation package

• Provide an implementation of gsclib/infrastructure/api/ for Windows
• Adjust cmake set in gsclib/common to select implementation properly depending on build os
• Adjust cmake set to be able to create an installation package for Windows

Replace log4cxx by log4cplus

Since log4cxx is not available as a conan package and last changes are several years ago, it should be replaced by a framework actively developed and integrated into modern tooling world.
