httpcheck

This module monitors one or more http servers availability and response time.

Charts

It produces the following charts:

• HTTP Response Time in ms
• HTTP Check Status in boolean

• HTTP Response Body Length in characters

Check statuses

Status	Description
success	No error on HTTP request, body reading and body content checking
timeout	Timeout error on HTTP request
bad content	The body of the response didn't match the regex (only if response_match option is set)
bad status	Response status code not in status_accepted
no connection	Any other network error not specifically handled by the module

Configuration

Here is an example for 2 servers:

jobs:
  - name: cool_website1
    url: http://cool.website1:8080/home
      
  - name: cool_website2
    url: http://cool.website2:8080/home
    status_accepted:
      - 200
      - 201
      - 202
    response_match: <title>My cool website!<\/title>

For all available options please see module configuration file.
