Peoplesoft Monitor Receives Error 500

I am baffled by the way a back end Weblogic web server handles newlines. The monitors I've deployed in LTM receive an Error 500 (Internal Server Error).

 

 

Here's the monitor as I have configured it in LTM:

 

 

GET /xmllink/E_REC/TCHH_WEB_DOWN_PAGE HTTP/1.1\r\nHost: peoplesoft-hr.ad.childrenshospital.org:7251\r\nConnection: close\r\n\r\n

 

 

It's all one line. When I test it by hand (telnet to port 80 and paste the string) I receive the error 500.

 

 

However, when I enter literal newlines, it works. For example:

 

 

GET /xmllink/E_REC/TCHH_WEB_DOWN_PAGE HTTP/1.1\r\n

 

Host: peoplesoft-hr.ad.childrenshospital.org:7251\r\n

 

Connection: close\r\n

 

\r\n

 

 

Any tips?

    I'm pretty sure the monitoring daemon, bigd, automatically appends a \r\n to the end of the send string. So if you include two pairs, three will actually be sent to the pool member.

     

     

    Do you still get a 500 if you take off the last \r\n so the send string:

     

     

    GET /xmllink/E_REC/TCHH_WEB_DOWN_PAGE HTTP/1.1\r\nHost: peoplesoft-hr.ad.childrenshospital.org:7251\r\nConnection: close\r\n

     

     

    If you still get a 500, can you take a look at the errors log for the web server and get any additional detail?

     

     

    You can also enable debug logging on bigd by setting a database key:

     

     

    b db Bigd.Debug enable

     

     

    The debug output is written to /var/log/bigdlog by default.

     

     

    To disable the debug, run:

     

     

    b db Bigd.Debug disable

    Thanks Aaron. The problem was the extra \r\n in the send string.

     

     

    Nice way to end the week!
