After my first problem, I thought that I had fixed everything and that I was able to monitor network services.

I was wrong.

My previously working services are now showing with a value of "4" in the last value panel and a nice red "x" is showing next to the services name... Needless to say, I am able to access the web page and get the needed information from the monitoring server:

prompt$ curl -Is http://host.com/testDB.php | head  -n 1
HTTP/1.1 200 OK

The only difference between the state of my setup now versus what it was at the time of my first topic is the software version change. I am now using the M4 version of netxms.

Here is the relevant part of the nxagentd.log file, where we can see that a connection is made between localhost and the agent. Then the log shows the proper shared secret and the proper request to send:

Is there anything that I could check/provide to get the monitoring of web services up and running once and for all?

Thanks for any input!
