Cachet plugin

This plugin can provide notifications for services that are failed in Cachet.

Configuration

There are two environment variables that this plugin needs:

• CACHET_API - URL of your Cachet top-level API endpoint. Example API URL https://status.company.com/api
• CACHET_ALERT_CONFIG - Path to file with notification configuration

Alert configuration is a JSON file which can be edited using bot commands. You can also edit it manually (remember to restart the bot)

JSON file is a list of objects which have following keys:

• channel - name of channels the configuration is for
• repeatGap - number of minutes between repeated outage notifications
• services - cachet component names which will be notified (or all for any outage)

Example:

[
  {
    "channel": "#outages",
    "services": [
      "all"
    ],
    "repeatGap": 120
  },
  {
    "channel": "#service1",
    "services": [
      "service"
    ],
    "repeatGap": 15
  },
  {
    "channel": "#team",
    "services": [
      "service2",
      "service3"
    ],
    "repeatGap": 60
  }
]

Above configuration would sent alerts to #outage for any outage every 2 hours. It would send alerts to #service1 every 15 minutes for service outages. And it would also send alerts to #team every 60 minutes if either service2 or service3 are in outage.

Commands

Bot recognizes following commands:

• services - list all services known to cachet
• subscriptions - list all active subscriptions for this channel
• subscribe <service> - subscribe to receive outage notification for <service>
• unsubscribe <service> - unsubscribe from outage notification for <service>
• repeatgap <minutes> - set how often alerts will be repeated (in minutes)

Configuration is automatically saved on each change through bot commands
