NYMMS is a monitoring framework that takes inspiration from a lot of different places.

It's goals are:

• Independently scalable components
• Fault tolerant
• Easily useable in a cloud environment
• Easy to add new monitors

There are many other goals, but that's a good start.

Here's a somewhat hard to understand diagram (at least without some explanation):

Currently the main requirements are:

• Python (2.7 - may work on older versions, haven't tested)
• boto
• PyYAML (used in a few backends, will eventually not be a requirement unless you need to use those backends)
• Jinja2 (needed for templating)
• Validictory (0.9.1 https://pypi.python.org/pypi/validictory/0.9.1)

Optionally:

• pagerduty (0.2.1 https://pypi.python.org/pypi/pagerduty/0.2.1) if you use the pagerduty reactor handler
