HTTP monitor with used domain name

Can you

 

 

1. Post the config for the monitor

 

2. Do a tcpdump and view the stream (To a dump file via -w and use wireshark to get the data)

 

3. Have a look at the web serve access and error logs for any status returns and errors

Hi, thanks, here it is

 

 

1)

 

monitor my_http_monitor {

 

defaults from http

 

partition Intranet

 

recv "OK"

 

send "GET /atest/web/default.aspx HTTP/1.1\r\n Host: myprivatesite.biz\r\n Connection: close\r\n\r\n\"

 

}

 

 

 

2) I have gone through tcpdump:

 

 

Requests are like this:

 

Expert Info (Chat/Sequence): GET /atest/web/default.aspx HTTP/1.1\r\n

 

 

Response:

 

Expert Info (Chat/Sequence): HTTP/1.1 400 Bad Request\r\n

 

 

I think those are most important from dump?

 

 

 

3) I will ask resp. people for that server.

 

 

 

 

Thanks,

 

Zdenek

 

send "GET /atest/web/default.aspx HTTP/1.1\r\n Host: myprivatesite.biz\r\n Connection: close\r\n\r\n\"is the last back slash (\) excess?

Hi, yes it's typo. That slash is out and situation still the same.

 

I get 400 The request is badly formed.

 

 

I have compared TCPdump when it works from IE and TCPdump when monitor from F5 and those are same, but wireshark doesnt show me everything..

 

have you tried to telnet to pool member and send a request?

 

 

GET /atest/web/default.aspx HTTP/1.1

 

Host: myprivatesite.biz

 

Connection: close

I tried to telnet to member and paste my command with \r\n. It didnt work.

 

 

Now I tried your template and I got 401 unauthorized, so there is some progress:-)

 

But why it didnt work with \r\n ?

But why it didnt work with \r\n ?since you have to press enter key, you do not need to put \r\n.

 

 

Now I tried your template and I got 401 unauthorized, so there is some progress:-)does web server require authentication? if so, what is authentication method?

 

 

this sol also includes send string with basic authentication.

hope this helps.

Hmm, I have to find out why IIS doesnt accept requests with \r\n and then I will try to solve that authentication issue. I am quite lost at the moment, I tried many shapes of requests but still get the same: Error 400. The request is badly formed

 

what i think is your web server requires authentication and OK will be received if authentication successes.

 

 

by the way, Aaron has written very good health monitor troubleshooting guide as follows.
