minitor

A minimal monitoring system

What does it do?

Minitor accepts a YAML configuration file with a set of commands to run and a set of alerts to execute when those commands fail. It is designed to be as simple as possible and relies on other command line tools to do checks and issue alerts.

But why?

I'm running a few small services and found Sensu, Consul, Nagios, etc. to all be far too complicated for my usecase.

So how do I use it?

Running

Install and execute with:

pip install minitor
minitor

If locally developing you can use:

make run

It will read the contents of config.yml and begin its loop. You could also run it directly and provide a new config file via the --config argument.

Docker

You can pull this repository directly from Docker:

docker pull kevineaton/minitor

The Docker image uses a default config.yml that simply pings a server every 30 seconds with exponential backup. This is likely not what you want, so when you run the Docker image, you should supply your own config.yml file:

docker run -v $PWD/config.yml:/app/config.yml kevineaton/minitor

Note that the image uses the version of minitor in pip and does not build from source.

Configuring

In this repo, you can explore the sample-config.yml file for an example, but the general structure is as follows. It should be noted that environment variable interpolation happens on load of the YAML file. Also, when alerts are executed, they will be passed through Python's format function with arguments for some attributes of the Monitor. Currently this is limited to {monitor_name}.

Contributing

Whether you're looking to submit a patch or just tell me I broke something, you can contribute through the Github mirror and I can merge PRs back to the source repository.
