Script for email alert and ping

I need help to update this script to if ping fails it would send another ping to another host (besides the email which is sent now if ping fails). How can this be done from this script?

#!/bin/bash

HOSTS="IP ADRESS"
COUNT=4

for myHost in $HOSTS
do
    count=$(ping -c $COUNT $myHost | grep 'received' | awk -F',' '{ print $2 }' | a$
    if [ $count -eq 0 ]; then
        # 100% failed
        echo "Server failed at $(date)" | mail -s "Server Down" [email protected]
        echo "Host : $myHost is down (ping failed) at $(date)"
    fi
done

You can put the ping stuff in a function. You do not need to process (grep) the ping result: you can rely on ping return exit status.

#!/bin/bash
HOSTS="IP1 IP2 IP3 IP4 IP5"
COUNT=4

pingtest(){
  for myHost in "$@"
  do
    ping -c "$COUNT" "$myHost" && return 1
  done
  return 0
}

if pingtest $HOSTS
then
  # 100% failed
  echo "Server failed at $(date)" | mail -s "Server Down" [email protected]
  echo "All hosts ($HOSTS) are down (ping failed) at $(date)"
fi

Try this with an array:

#!/bin/bash
HOSTS_ARRAY=("IP_ADRESS" "ANOTHER_IP" "YET_ANOTHER")
COUNT=4
for myHost in "${HOSTS_ARRAY[@]}"
do
     count=$(ping -c $COUNT $myHost | grep 'received' | awk -F',' '{ print $2 }' | a$
     if [ $count -eq 0 ]; then
         # 100% failed
         echo "Server failed at $(date)" | mail -s "Server Down" [email protected]
         echo "Host : $myHost is down (ping failed) at $(date)"
     fi
done
