I am helping in a trial where the customer has a deployment of HAProxy with one or more workers on the same host. When there is one worker/host oneworker.png, the HAProxy metrics and further details are picked up, but when there are more workers, like four in this case fourworkers.png these are not picked up.
Are you still having an issue with this? After reviewing the screen shot, it appears there are no active process running as shown by the "- Services" on top of the info graphic. I am also assuming the Service has been restarted after installed?
