    +# Critical Analysis of the broker
    +
    +There are a few things that can go wrong on a production environment:
    +
    +- Bugs, for more than we try they still happen! We always try to correct them, but that's
the only constant in software development.
    +- IO Errors, disks and hardware can go bad
    +- Memory issues, the CPU can go crazy by another process
    +
    +For cases like this, we added a protection to the broker to shut itself down when bad
things happen.
    +
    +We measure time response in places like:
    +
    +- Queue delivery (add to the queue)
    +- Journal storage
    +- Paging operations
    +
    +If the response time goes beyond a configured timeout, the broker is considered unstable
and an action will be taken to either shutdown the broker or halt the VM.
    +
    +You can use these following configuration options on broker.xml to configure how the
critical analysis is performed.
    +
    +
    +Name | Description
    +:--- | :---
    +critical-analyzer | Enable or disable the critical analysis (default true)
    +critical-analyzer-timeout | Timeout used to do the critical analysis (default 120000
milliseconds)
    +critical-analyzer-check-period | Time used to check the response times (default half
of critical-analyzer-timeout)
    +critical-analyzer-halt | Should the VM be halted upon failures (default false)
