You can now use Guardian from anywhere on your system.

Usage

$ guardian --help
usage: guardian [-h] -c CONFIG_FILE [--email] [--irc] [--html]

optional arguments:
  -h, --help            show this help message and exit
  -c CONFIG_FILE, --config CONFIG_FILE
                        Configuration file (YAML).
  --email               Send notification of failed test(s) via email.
  --irc                 Send notification of failed test(s) via IRC.
  --html                Generate a HTML status page.

In order to use notification via IRC you need to install irker. irker is very easy to install and to run, no configuration is needed. Once executed, irker will wait for JSON formatted messages on the port 6659. irker will automatically join the channel you have specified in the Guardian configuration file. irker will maintain connection state for multiple channels, avoiding obnoxious join/leave spam.

Configurations related to the sending of emails are in the same file.

Examples

The goal of the INI configuration file is to set global variables (IRC channel, SMTP server, etc.). If you do not create your own configuration file, the default one will be used automatically.

The services to monitor must be described in one (or several) YAML file(s).
