Disable ICMP echo reply for the VIP based on the number of active members in the pool

Updated script:

 Define the correct variables per application
 POOL_NAME = set the correct pool name for the application
 VIP_MONITOR_ADDR = IP address of the application Virtual Server VIP.
 MIN_ACT = minimum number of active members in the pool to declare pool active





POOL_NAME="web4-internal-pool"
VIP_MONITOR_ADDR="172.25.40.99%4004"
MIN_ACT="3"




CUR_ACT=`tmsh show ltm pool $POOL_NAME members  | grep "Current Active"  | cut -d: -f2 | xargs`

if [ $CUR_ACT -lt $MIN_ACT ]; then
 echo "$(date): FAIL- Number of active nodes for pool $POOL_NAME is $CUR_ACT which is less than minimum active $MIN_ACT" >> /root/${POOL_NAME}-script.log;
        tmsh modify ltm virtual-address ${VIP_MONITOR_ADDR} icmp-echo disabled
else
 echo "$(date): PASS- Number of active nodes for pool $POOL_NAME is $CUR_ACT which is equal or greater than minimum active $MIN_ACT" >> /root/${POOL_NAME}-script.log;
        tmsh modify ltm virtual-address ${VIP_MONITOR_ADDR} icmp-echo enabled
