HTTPMonitor_cURL_ProbeTimeout

OK, I see where it's going sideways now.

CAUCHOPORT is not defined anywhere in your monitor, and without that value, the cURL call is failing, and so no request is being sent to the pool member.

If you just change the name of the PORT var back to CAUCHOPORT in the monitor definition, you should be up & running to mark pool members UP.

However, to mark pool members DOWN, you'll need to make another change: Remove the alias destination port from the monitor definition. The script must be passed the pool member's defined port in order to mark it DOWN using the bigpipe command.

So your monitor def would look like this:

monitor curlcaucho {
  defaults from external
  run "curlcaucho"
  POOL "cwmp.stage.80"
  CAUCHOPORT "4004"
  P_TIMEOUT "5"
  RECV "w50-`echo $IP | cut -d. -f4`.c50.domain.com:6802 (ok)"
  URI "/caucho-status"
}

Give that a try.
