I am looking for help to configure a monitor/irule to login to a web page with credentials then check the service up/down when the login is successful. It would be really appreciated if someone could be able to share/help me with coding/programming to achieve this.
I have gone through some F5 articles but did not find a better solution.
Finally, I did it! Staging, UA, DEV environment pools are running currently using this custom health monitor and I have been implementing this in the production environment without any issues.
Configuration:
Create new health monitor with the following settings:
From the F5 GUI:
Send string: POST /Account/SignIn HTTP/1.1\r\nHost: host.domain.com\r\nConnection: Close\r\nContent-Length:10\r\nAuthorization: Basic ZjU6ZjVwYXNzd2Q=\r\n\r\0123456789
Receive string: 302 Found
Interval: 10 seconds (use whichever is acceptable)
Timeout: 31 seconds (use whichever is acceptable)
Since we need the monitor to login to the website with the credentials we provide, do the following:
To generate the encrypted auth string like in the send string above:
Log in to the BIG-IP command line.
Generate an encryptedauthstring by using the following syntax:
echo -n 'username:password' | base64
For example, if you used the user namef5and the passwordf5passwd, the output would appear as follows:
ZjU6ZjVwYXNzd2Q=
To test the monitor before applying it to the corresponding pool on F5, you can test using the below commands:
From F5 CLI:
tmsh
run /ltm monitor http <health monitor name> destination <dest_ip> show /ltm monitor http <health monitor name> test-result
