watcher 4 - hardcoded poll

watcher 4 gets status requests every 5 seconds.
setting up monitoring for multiple services (W5)

watcher 4 takes a “poll time” parameter in bootstrap.js, so poling
frequency can be adjusted.

created watcher 5 in anticipation of setting up monitoring for multiple
services: biggest issue is saving information separately in the same
database. More on this on Friday, supposedly.
