What?

A work in progress generic router that takes JSON from one middleware source and route it to another destination based on an expression language from JGrep.

This is a work in progress, can't be used yet.

foo.route

expression "headers.scode >= 300 and body.origin = 'apache'"

processor do |headers, body|
  case body.vhost
    when "foo.com"
       target "/queue/errors.foo"

    when "bar.com"
       target "/queue/errors.bar"

  end

  target "/queue/errors.all"
end

The idea is that the expression is used to do course selection over a stream of messages on the middleware that contains JSON, the processor block is then called for ones that match the expression where it can create a series of STOMP destinations where the message will be sent.

In this case any HTTP log with a status >= 300 will be processed by this router. Errors from the vhost foo.com and bar.com goes to specific destinations while everything also goes to the all errors destination.
