Try removing some variables - I'm unfamiliar with PM2, so I'd try just
running your node server directly from a console, and then having monit
send it's query (add a minutely query to localhost:81 or something for
testing). If the node process is exiting, it should become apparent why
(that being said, I'd hope that PM2 would show similar information in its
logs somewhere as well, but having one less moving part should make it
easier to isolate the issue).
Just a shot in the dark, but my guess would be that whatever data monit is
sending is thought to be malformed http by node's native http parser and
that's throwing an exception or something, although in theory your
process.on('uncaughtException') is supposed to grab that (though if PM2 is
hooking uncaughtException, yours might be being ignored or something).
Hope this helps!
