Features
--------

- [x] Creates & Resolves Incidents
- [x] Posts monitor lag to cachet graphs
- [x] Updates Component to Partial Outage
- [x] Updates Component to Major Outage if already in Partial Outage (works well with distributed monitoring)
- [x] Can be run on multiple servers and geo regions

Configuration
-------------

```
{
  "api_url": "https://<cachet domain>/api/v1",
  "api_token": "<cachet api token>",
  "insecure_api": false, // optional, false default, set if your certificate is self-signed/untrusted
  "monitors": [{
    "name": "Name of your monitor", // required, friendly name for your monitor
    "url": "Ping URL", // required, url to probe
    "method": "get", // optional, http method (defaults GET)
    "strict_tls": true, // self-signed ssl certificate
    "interval": 10, // seconds between checks
    "metric_id": <metric id>, // post lag to cachet metric (graph)
    "component_id": <component id>, // post incidents to this component
    "threshold": 80, // If % of downtime is over this threshold, open an incident
    "expected_status_code": 200, // optional, expected status code (either status code or body must be supplied)
    "expected_body": "P.*NG" // optional, regular expression
  }],
  "system_name": "", // optional, system name to identify bot
  "log_path": "" // optional, defaults to stdout
}
```

Vision and goals
----------------

We made this tool because we felt the need to have our own monitoring software (leveraging on Cachet).
The idea is a stateless program which collects data and pushes it to a central cachet instance.

This gives us power to have an army of geographically distributed loggers and reveal issues in both latency & downtime on client websites.
