CrashHook is a rack middleware for handling exception in your rack-based application.
It sends a http request with exception information, backtrace and environment details to your url via specified method.
gem install crash_hook
YOUR_RAILS_APP::Application.config.middleware.use CrashHook::Middleware, {
:url => 'YOUR_URL'
}
You can add any exceptions into ignore list:
YOUR_RAILS_APP::Application.config.middleware.use CrashHook::Middleware, {
:url => 'YOUR_URL',
:ignore => [
'NoMethodError'
]
}
Configuration block
CrashHook.configure(:url => 'YOUR_URL')
And insert the following into error handler:
errors do
CrashHook.notify(request.env['sinatra.error'], request.env)
# your stuff, render 500, etc
end
Please note that this will work only in production mode, since in development mode Sinatra is overriding this method with a nice looking exception backtrace page.
In other rack apps (config.ru):
require 'crash_hook'
use CrashHook::Middleware {
:url => 'YOUR_URL',
:method => :post
}
In order to use crash-server application you need to configure your app like this:
YOUR_RAILS_APP::Application.config.middleware.use CrashHook::Middleware, {
:url => 'YOUR_URL',
:params => {:api_key => 'API_KEY'},
:logger => Rails.logger
}
You can use these options during configuration:
- :url — Target URL (required)
- :method — Request method (default: :post)
- :params — Extra parameters for the request (ex.: api key, app ID, etc.)
- :format — Report format (:form, :json, :yaml), (default: json)
- :ignore — Array of exception class names you want to ignore, (default: [])
- :logger — Set a logger for delivery errors, (default: nil)
Each request has a following structure:
crash:
exception:
class_name: "Exception class name"
message: "Exception message"
backtrace: "Exception backtrace"
environment: "rack request environment"
framework: "rails"
version: "crash_hook version"
Framework is being auto-detected and could one of the following:
- rack (default)
- rails
- sinatra
