LTM: Interface Failsafe

I have modified the script to avoid potential false failover.

modifed by Vincent Li v.li@f5.com to avoid possible I/O buffer

 

Pass in each interface to monitor via the Arguments field in the GUI

 

Collect arguments (first remove IP and port as we don't use those)

 

shift

 

shift

 

interfaces="$*"

 

b interface show > /tmp/b_interface_show

 

for i in $interfaces ; do

 

status=`b interface $i show | tail -1 | awk '{print $2}'`

 

status=`grep "^ *$i " /tmp/b_interface_show | awk '{print $2}'`

 

if [ "$status" != "UP" ] ; then

 

logger -p local0.notice "$MON_TMPL_NAME: interface $i is not up (status: $status)"

 

exit 1

 

fi

 

done

 

All specified interfaces are up...

 

logger -p local0.notice "$MON_TMPL_NAME: interface $i is up (status: $status)"

 

echo "up"

 

exit 0
