NimbostratusPeoplesoft 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

Ray_Sbrusch_941Thanks Aaron. The problem was the extra \r\n in the send string.
Nice way to end the week!
