Need help on CLI command to fetch < VIP Name + current connections >

Hi Blue_whale you could use a bash script to do this pretty easily (or write a tmsh script to do the same, but bash might be a little easier if you're not familiar with the tmsh scripting):

#!/bin/bash

tmsh_show=$(tmsh show ltm virtual recursive all field-fmt)

vipname=""
vipconns=""
vipstate=""

echo "$tmsh_show" | while IFS= read -r line; do
    line=$(echo "$line" | sed -e 's/^[ \t]*//' -e 's/[ \t]*$//')

    if [ -z "$line" ]; then
        continue
    fi

    if [[ "$line" =~ ^ltm\ virtual\ ([^\ ]+) ]]; then
        vipname="${BASH_REMATCH[1]}"
    fi

    if [[ "$line" =~ ^clientside\.cur-conns\ ([0-9]+) ]]; then
        vipconns="${BASH_REMATCH[1]}"
    fi

    if [[ "$line" =~ ^status\.availability-state\ ([^\ ]+) ]]; then
        vipstate="${BASH_REMATCH[1]}"
    fi

    if [[ "$line" == "}" ]]; then
        printf "Vip Name: %s\n" "$vipname"
        printf "Current Connections: %s\n" "$vipconns"
        printf "Availability State: %s\n" "$vipstate"
        printf "\n"

        vipname=""
        vipconns=""
        vipstate=""
    fi
done

which on my fairly empty test box running 15.1.x shows results like this:
