Gobeet

Gobeet is a simple website health-checker written in go

Gobeet takes a configuration file and will consistently ping your website, sending you an email if any route is down for too long.

Arguments

Gobeet takes two command line arguments:

• --config=config.json: Points to the configuration file to use.
• --password=******: The email password for the configured email address.

Config File

Gobeet configuration files are composed of three main sections

• Email Configuration
• Websites
• Pages

Email Configuration

This is where email is configured. If you don't want to get emails, don't add this section.

A standard email configuration looks like this:

"email" : {
  "recipients": [
    "[email protected]",
    "[email protected]"
  ],
  "template": "sampletemplate.tmpl"
  "address": "[email protected]",
  "server": "smtp.recipient.com",
  "port": "587",
}

• recipients: Who gets an alert when your site is down.
• template: Path to a valid Golang template to use for the email.
• address: The email address to send out the alerts.
• server: SMTP email server.
• port: STMP email server port. Usually 587.

Sites

A list of all domains to test.

A typical sites list will look like so:

"sites": {
  "url": "www.github.com",
  "interval": 60,
  "pages": [
    ...
  ]
}

• url: The URL to test.
• interval: How many seconds to wait before testing all pages in the site again
• pages: A list of pages

Pages

A page is simply a part of your site that gets tested at a specified interval.

{
  "url": "https://github.com/danman113/",
  "method": "GET",
  "timeout": 5000,
  "status": 200,
  "duration": 10
}

• url: The page to test.
• method: The HTTP method to test the page with.
• timeout: The number of milliseconds to wait before deciding if the page is down.
• status: The expected HTTP status code the page is supposed to return. Gobeet will send an error if this result is different than this.
• duration: How many seconds to wait after a page is down before sending an email.

Email Template

Gobeet uses standard Golang HTML Templates. The two exposed variables are:

• Site: The current page that's down.
• Error: The error object.

<div class="header">
  <h1>Your website, <a href="{{.Site.Url}}">{{.Site.Url}}</a> has been down for {{.Site.Duration}} seconds!</h1>
</div>
<div class="content">
  <h3>The error is: </h3>
  <div class="pre">
    {{.Error}}
  </div>
</div>
