Pimon is a simple server monitor designed for the Raspberry Pi. Currently it only works with the Raspberry Pi 1 (256MB and 512MB versions).
What do I need to get it to work?
- Clone this repo: git clone git://github.com/pedrocarrico/pimon.git
- bin/pimon start # run the sinatra app
- go to http://localhost:3000 and PROFIT! Optionally you may install it as a gem and run it, please check "Installing as a gem" further down.
Configuration is done through a YAML file, you may check some examples on the config directory.
Installing as a gem
gem install pimon
After installation just do pimon start and go to http://localhost:3000 and check your stats. If you want you may run Pimon with other options:
Usage: pimon start|stop [options] Options: -c, --config CONFIG YAML configuration file for pimon -d, --daemonize Run Pimon daemonized in the background -e, --environment ENVIRONMENT Application environment (default: "development", options: "development", "production") -i, --interface INTERFACE Hostname or IP address of the interface to listen on (default: "localhost") -p, --port PORT Port to use (default: 3000) -P, --pid PIDFILE File to store PID (default: /tmp/pimon.pid)
(This will only work on your Raspberry Pi and perhaps some other linux distros, check the quirks section for more info).
To run the coverage suite:
Results will be in coverage/index.html directory.
Pimon uses vmstat and free to collect it's stats from the operating system and these are only
available on operating systems that have the /proc filesystem.
So if you want to develop on a Mac you may use the mock implementations that are in the bin directory.
The mock implementations are programmed in C and mimic the output of vmstat and free.
They just change and generate some random values on the observed stats using /dev/urandom.
To use them you must first compile them using make and then include the bin directory of this project in your $PATH to have them available when you run the sinatra application. The temperature stat is available with the latest Raspbian and Arch Linux distros on your Raspberry Pi and will (may) not work if you're developing on other systems. Pimon only works with Ruby 2.0+.
