OK, so the good news is that your Director is definitely up and working. The bad news is that it seems like Health Watch isn't. At least it's not getting metrics/info from the Director.
It seems like this is the metric that you're referring to, is that correct?

If so, I'd suggest trying the two recommended actions from that link:
- Ensure the bosh-health-check app is running in the healthwatch space of the system org. Check the app logs for any obvious errors.
- SSH into the running bosh-health-check app and copy the BOSH manifest from /home/vcap/app/health_check_manifest.yml. Try to deploy it manually on the BOSH Director and check for errors.
