Title: A couple Bernard fixes

Fixes a few issue I ran into when I was troubleshooting Bernard today.

1. Fix an out-of-date import of AgentSupervisor
2. Fix a bug where the last check in a path is loaded twice.
3. Log a debug message when we can't parse out perf data so it doesn't just fail silently.
