Hello, I would like to suggest a ping plugin (as there are already several plugins with the name ping I will skip this part).
With this plugin you can see the ping of you and also of other players, with menu for staffs.
Versions: 1.8, 1.9, 1.10 (and possibly 1.11)
Information and Download: https://www.spigotmc.org/resources/ping.30936
Hope you like it
