tcp perl server health monitor

Hmmm, it's hard to interpret this to be honest. Can I advise you save this to a file and analyse it in Wireshark or something similar. In the third test you seem to be sending a \r\r first?

 

 

You should also capture the actual monitor at work. Interesting to note the %'s in the telnet test don't appear in the other two, perhaps this is a clue? I'm happy to look at the captures if you're happy to upload them but I can understand why you wouldn't want to.
