It's probably not your fault. Not many people use the monitor port, and
it's possible it's been broken by recent zope versions. By the looks of
the error message, it doesn't look like it should be difficult to fix. A
Collector issue might be in order.

A Zope instance that is a ZEO client sees the same objects as other Zope
instances. For all intents and purposes, it is as if you're talking to a
single Zope instance. Since you described that you could use Zope from
python console if you didn't start it, using a ZEO instance the same way
looks like it's exactly what you need. You might not understand what I'm
talking about until you try and install ZEO for yourself
