I am running the latest Zen Load Balancer (3.0.3) and am noticing a strange
issue with FarmGuardian. I have configured a TCP Farm to monitor an Exchange
2013 CAS that I am testing in development. I have both servers configured and
am using the following FarmGuardian check:
check_http -H server.example.com -I HOST -p PORT -S -u /owa/auth/logon.aspx -R
'This Should Fail'
The result of this should fail. In the since the RegEx is not returned. In the
log, I see the following (IP Addresses removed):
command: /usr/local/zenloadbalancer/app/libexec/check_http -H
server.example.com -I X.X.X.X -p 443 -S -u /owa/auth/logon.aspx
-R 'This should Fail'
/usr/local/zenloadbalancer/app/libexec/check_http -H server.example.com -I
X.X.X.X -p 443 -S -u /owa/auth/logon.aspx
-R 'This should Fail' timed out.
timedout: 1
errorcode: 512
No state changed for the backend.
The servers timeout is: 10
checking:
farmname: Exchange
timeout: 10
blacklist: 30
timetocheck: 5
portadmin: 19446
server[0]: X.X.X.X:443
server[1]: X.X.X.X:443
check: check_http -H server.example.com -I HOST -p PORT -S -u
/owa/auth/logon.aspx -R 'This Should Fail'
execution in Wed May 14 12:36:05 2014 ::
server[0]: X.X.X.X:443
Backend status 0: fgDOWN
This is telling me that FarmGuardian is correctly failing and should disable
the backend server. However, it doesn't. The status still shows up in the
control panel and if I navigate to the farm IP, it still takes me to the
backend server whereas in this case, it shouldn't (and I don't want it to).
Is there something wrong with FarmGuardian in the latest code?
