HTTPS Monitor Healthcheck Failing

Hi All,   I'm trying to monitor the health of a pool by using a send string and receive string.   the following path as been setup on both the IIS servers:   https://10.54.118.11/portal/por...

I think your send string might be a little off.

 

You have "Host: Close" when it should be:

 

"Host: 10.54.118.11\r\nConnection: close\r\n\r\n"

 

 

Hope that helps!

    Hi Dylan,

     

    Got it working with the following:

     

    TYPE : HTTPS SEND STRING : GET /portal/portaladmin/healthCheck HTTP/1.1\r\nHost: Close\r\n\r\n

     

    RECEIVE STRING : healthcheck

     

    the server guy stopped IIS on one of the servers and the F5 removed it from the pool

     

    logs:

     

    Dec 19 14:50:30 ITF55175HDC1-INT1 notice mcpd[14150]: 01070638:5: Pool /Common/ArcGIS_WEB_Pool member /Common/PLHRESRWEB001:443 monitor status down.

    and then once enabled, came back into the pool...noticed there was a 200 OK being returned in the CURL output, I just took a string which was "healthcheck"

     

    will do some failover testing with the server admin tomorrow
