NimbostratusMonitor help
Hi,
We are on version 9.4.8. We came from version 4.6.4. In 4.6.4, we had custom monitors set up of which we lost in the upgrade that would monitor our web application. I have setup a custom monitor to do this, but the bigip keeps marking the node member as down.
My monitor:
Send String: Get /somepage.asp
Receieve String: HTTP/1.1 200 OK
I got the receive string from doing a fiddler trace and reviewing what is returned. Perhaps this is wrong, but I am at a loss as to what I am doing wrong. It seems like it should be really simple. Thanks for any help!

Can you try this for the send string:
GET /somepage.asp HTTP/1.1\r\nHost: \r\nConnection: Close
And this for the receive string:
HTTP/1.(0|1) 200
For details on send strings and the bigd behavior in recent versions you can check this SOL:
SOL10655: Change in Behavior: CR/LF characters appended to the HTTP monitor Send string

K-DubbThanks for the response Aaron. I have revied the SOL. Also, I tried the syntax from your post, and the node is still saying offline. Any suggestions?- hooleylistYou can check this wiki page for more suggestions on troubleshooting monitors:

Aaron - K-DubbI know why it is not working. It is because it is responding with a 302 (redirect). The page I am requesting checks to see if the client is using IE7 or IE8. If not, it redirects it to a different page. I suppose my receive string could be changed to expect a 302, but I am not sure if that is best...
