This could be because you hit a bug. It is also possible that this binary
or one of the libraries it was linked against is corrupt, improperly built,
or misconfigured. This error can also be caused by malfunctioning hardware.
We will try our best to scrape up some info that will hopefully help
diagnose the problem, but since we have already crashed, 
something is definitely wrong and this may fail.

# These rules are designed to be effective versus /distributed/ brute force
# attacks. While they will function just as well against attacks which are
# /not distributed/ they will deny access to all XML-RPC method calls
# namespaced with the prefix "wp."

# An IP-based version of these rules may be more appropriate for sites which
# attacked from just a few distinct IP addresses.

Sensu

monitoring not only an ops problem. devs need to be on board, looped in

poor monitoring coverage

rather than making a large change, iteratively integrate sensu, gradually replacing nagios

exploring what success looks like; observations on whether or not it was better than the status quo
