External Monitoring broken in TMOS 11.2.x??

Hi,   I discovered a strange problem with external monitors on 11.2.x. After an upgrade attempt from 10.2. to 11.2., all my external monitors (perl scripts) ceased to work. There was no message at...

More or the less I ran in the same problem: external monitor script didn´t work though I´m pretty sure it has to :-)

 

First misinterpretation was that when I ran the monitor manualy under /config/filestore/files_d/Common_d/external_monitor_d/:Common it worked!

 

Solution: you have to "know" :-) that the ip address that is passed to the script is in IPv6! So you have to "clean" this up at the beginning like this:

 

remove IPv6/IPv4 compatibility prefix (LTM passes addresses in IPv6 format)

 

IP=`echo ${1} | sed 's/::ffff://'`

 

If you have a look on the example in BigIP you will find this too - though it is not intuitive BUT written in the comment :-)

 

Hope this helps...
