NimbostratusDNS Monitor Issue?
All,
We have tried using the DNS Monitor posted on Dev Central http://devcentral.f5.com/wiki/defau...ookup.html and can't seem to get this working. I followed the instructions as best I could, when I do a tcpdump I don't even see the monitor being generated. I placed the montior txt script in its proper repository /usr/bin/monitors/DNS_Monitor.txt with 700+ permissions and added the arguments "test1.xyz.com" "10.10.10.10" and still nothing. Am I missing something?
[root@F5-LTM1:Active] config ls -la /usr/bin/monitors
total 32
drwxr-xr-x 3 root root 4096 Sep 22 15:44 .
drwxr-xr-x 3 root root 12288 May 15 17:47 ..
-rwx------ 1 root root 1494 Sep 22 10:06 DNS_Monitor.txt

Hi JC,
Do you get an UP message if you run the monitor manually from the command line?
If that doesn't work, you can add debug to the script using this template as a guide:

JCMATTOS_41723I did a cli test and it shows UP.
[root@F5-LB2:Active] config /usr/bin/monitors/DNS_Monitor.txt 10.10.10.10 53
UP
I'll try the debug next and let you know the results. Thx Aaron!- JCMATTOS_41723
Aaron,
Question wanted to see if my argument syntax was correctly stated as well, it seems i see a lot of conflicting documents on how to apply this thru the GUI.
[root@F5-XX-LB1:Active] config b monitor DNS_Monitor list
monitor DNS_Monitor {
defaults from external
interval 10
timeout 35
args "test1.xyz.com 10.10.10.10"
run "DNS_Monitor.txt"
}
