Hello,
We are about to put the ZLB into production but we would like to receive
alerts when a backend server is not reachable.
For this I wanted to use our monitoring system and check the logs
generated by Farmguardian.
For the http checks it works OK, i'm using the "-e" switch and when the
text is not detected I see in the logs "execution error" instead of
"execution: OK".
However for the SMTP check, it doesnt seems to work. I've created a
wrong server and intentionnaly misconfigured a backend server to port
2552 instead of 25, however farmguardian keeps saying it's OK.
farmname: ZLB-EXCH-HUB
timeout: 5
blacklist: 30
timetocheck: 10
portadmin: 18828
server[0]: 192.168.135.5:2552
server[1]: 192.168.135.6:25
check: check_smtp -h HOST -p PORT -t 2
execution in Tue Jul 17 10:56:13 2012 ::
server[0]: 192.168.135.5:2552
**execution OK in server 0
errorcode: 0
server[1]: 192.168.135.6:25
**execution OK in server 1
errorcode: 0
server[2]: 1.2.3.4:25
**execution OK in server 2
errorcode: 0
In CLI however, it says it detects it's CRITICAL because connection fails
root@VMWZLB001:/usr/local/zenloadbalancer/logs#
../app/libexec/check_smtp -H 192.168.135.5 -p 2552 -t 2

root@VMWZLB002:~# /usr/local/zenloadbalancer/app/libexec/check_smtp -H
1.2.3.4 -t2
CRITICAL - Socket timeout after 2 seconds
Any idea what i'm doing wrong?
Thanks
