Using the iapp for sharepoint:

Alexander, my first thought would be to use a basic HTTPS monitor. If this works then it points to some setting in the monitor above. Have you connected via curl using the same Send string and does this work or not?

I think you need to remove the last pair of "\r\n". This pair denotes an empty line that separated http headers and body. The header for authentication using your username and passowrd must be included in the header part.

And you need to have a receive string defined as well.

Resuming the actual state.

1. When I execute the following from the command line of the big-ip:

   curl --verbose -k -i https://sharepoint.publicdomain.de/sites/test\r\nConnection: Close\r\n --ntlm -u username:password

   I get a

   HTTP/1.1 200 OK

   and a whole html page. OK
2. The monitor is configured as displayed in the picture:

So, where is the error in the health monitor?

Regards, Alexander

It doesn't matter if I fill in the above regular expression or not. The monitor stays red anyway. Just filled it in to follow the suggestion from Jie.

OK, without knowing your LTM version I've tried to create the Send String I'd use for this. Do either of these work (depending on LTM version and the actual host name)?

10.2.x / 11

GET /sites/test HTTP/1.1\r\nHost: sharepoint.domain.com\r\nConnection: Close\r\n\r\n

9.4.x, 9.6.x, 10.0.x, 10.1.x

GET /sites/test HTTP/1.1\r\nHost: sharepoint.domain.com\r\nConnection: Close

Version is 11.4

Found some typos in my string, corrected them and the monitor is still red.

The actual connection string:

GET /sites/test HTTP/1.1\r\nHost: sharepoint.domain.de\r\nConnection: Close\r\n\r\n

The syntax looks good. Perhaps it's best to refer you to this doc, if you haven't already seen it: https://devcentral.f5.com/wiki/AdvDesignConfig.TroubleshootingLtmMonitors.ashx

Turning on debugging, I get the following /var/log/bigdlog entries. The interesting part is in the middle.

What does error=5 mean?

Hey there,

I cannot say exactly what I have changed, but the sharepoint now is available and the problem seems to be solved.

The problem probably had to to with SSL encryption or the self-signed certificate. After I changed the binding (Port, Certificate etc.) and changed it back, unexpectedly the monitor became green.

Thanks to all for helping! I've learned a lot :-)

Regards,

Alexandner
