An useful and lightweight /ping command with latency and server load, for Bukkit. Download link.
/ping — displays own ping
/ping <player> — displays ping for this player
Aliases: /lag, /latency
Permission: ping.ping (default true).
If the latency or server load is high, the command displays a diagnostic to help the player understand its performances problems.
Permission: ping.diagnostic (default true).
By using /toggleping (or clicking on “keep displayed” in the /ping output), the ping can be kept
displayed above the inventory, on the action bar. That can be useful to monitor your connection, if
it is bad, or the server performances.
Permission: ping.toggleping (default true).
