tping is a bash alias I once got from an old co-worker. It's ping, but with a timestamp. Instead of looking at the increased icmp_seq number you now have a timestamp. Here's how it looks like:

$ tping 192.0.2.10

The host went down on 09:32 and was back up on 09:36. This was a scheduled reboot.

.bashrc function

The shell code for in your .bashrc file:

tping() {
    ping $@ | while read pong; do 
        echo "$(date +"%T"): $pong"; 
    done
}
alias tping=tping

Start a new shell our source .bashrc after you added this function.

Prettyping

Another tool to get more visual information from ping is prettyping. It's open source on github and looks like this:

The red exclamation marks in the image represent a reboot of that server.
