Monitoring ignores invalid args

[derekcollison]

So /connz?testpub=foo should error but does not.

Hello, I'd like start contributing to the project and I found this marked as help wanted.

Is it still something you wanna implement with help ?

To confirm the desire for an error, is this so typos are not overlooked? I think for most websites, unknown GET params are just ignored. However since this behaves more like an API, unknown/invalid params would be justified.
