Odo is a simple server status tool. At its current state it simply retrieves CPU, memory and network stats. It is not very sofisticated, but it does the job for simple monitoring (such as my personal web server).
It uses a websocket connection to the frontend, which is a vanilla JS application written in TypeScript. The stats are retrieved by parsing the output of system commands (netstat, uptime...), reading /proc/, and using a patched version of sysstat.
You might need to install net-tools on some systems.
The backend is a simple Tornado application. Due to the nature of the project, I could not find a proper way to run it on Docker. We'll use a virtual environment instead.
virtualenv -p python3.8 env
source env/bin/activate
pip install -r requirements.txt
git submodule update --init
cd mpstat
patch -f mpstat.c ../mpstat.patch
./configure && make
cd ..Now edit conf.template.py and set your host and port. Disable the debug mode for deployment. Copy it to conf.py.
The frontend is compiled with Webpack. Fortunately, here we can use Docker.
cd frontend
docker-compose buildSimply start the docker container:
docker-compose up -dSimply start app.py. A template for supervisord is provided in deployment/.
A proxy is required to create a single point of entry for frontend and backend. You can use the nginx template in deployment/ for reference.
