tcp perl server health monitor

I am a small issue were I want to monitor a service on one our linux servers the server is running tcp perl server service were you send info and and send info back. When I logon to my big-ip through command and do a telnet test example below it works , but when I input info but when I fo to health monitors and add in send string a=1\r\nid=1234456\r\nfirstname= bob\r\n recieve string it will just fail I have even tried to to copy and paste a=1\r\nid=1234456\r\nfirstname= bob\r\n through telnet session and it just fails also tried to test by doing it sections a=1\r\n and the other parts separtely and it fails I believe it does not like syntax \r\n. Has anyone come around this issue and how did you resolve it or can you provide some advice. Thx in advance

 

 

Example

 

telnet 1.1.1.1 10000

 

 

INPUT

 

a=1

 

id=1234456

 

firstname= bob

 

 

OUTPUT

    Assuming this is a tcp Monitor, can you try both just \r and \r\r with the monitor.

     

     

    This command might help with your testing: [tmsh] run util test-monitor ‘name’.

     

     

    Also, what version are you running, I think some versions put the \r or \r\n in for you so you may be doubling up?

    Hi I am running version 11.2.1 I entered the send string below with just \r and same issue also when I run run util test-monitor I get the error message below. And you are correct I have selected tcp monitor

     

     

    run util test-monitor server_1000 address 1.1.1.1 port 1000

     

    can't run 'server_1000' monitor manually: external executable not found

    Hmmm. Could you post the CLI configuration of your monitor? The error suggests it might be misconfigured.

    Hi, yeah the comment from "02/01/2013 12:27 PM" is what pulled by conf file. I have added send" a=1\r\rid=1234456\r\rfirstname= bob\r\r" but in the big ip conf its showing with double brakcets "send a=1\\r\\rid=1234456\\r\\rfirstname= bob\\r\\r" in bigip conf is that normal?

    Probably, it's just escaping the \'s. Any luck with \r\r configured in the monitor (ignoring the config file)?
