LagMeter

Table of Contents

Lets you check the server lag, in ticks-per-second.

Bukkit version does not matter for this plugin.

Description

A lot of plugins tell you that something happens "every X seconds, depending on lag." That's because when the server is overworked, there are less than 20 ticks per second. This plugin will measure the number of ticks per second, and output it on your screen as a "Lag Meter." The plugin can also output the amount of memory free, alert those with a specific permission node when the ticks per second or free RAM goes down too far, and even measure the server's ping to google.com.

Some of them are a little out of date, but you get the idea.

Download

CI/build (Jenkins) server
You can always pick up the latest compiled version of LagMeter on my CI server. Note that BukkitDev doesn't warrant the safety of these builds, etc, but it's all pulled from GitHub anyways, so you could compile it yourself or look at the commits. Lagmeter is more stable than Lagmeter-bleed.

Try this instead:

ConsoleCommand: /stoplag;/stoplag -c;/lag;/butcher

Also, there is a message sent every time the interval for the checker ticks. If the interval is 10, you will get a message every 10 minutes.

Can u add a message maybe every 10 Minutes with the TPS?

Every 10 Min server message:

[Server] [####] 20.0 TPS

so users can see that the server is running good

The entities and chunks? Turn off display of entities and chunks on load at the bottom of the General configuration section. Check the configuration page for more info if your config is out of date.

Could you add the option to remove the spam at startup ? Its kinda useless to print all that when the server isn't ready yet.

You'd be right on that one.

Could be very neat. I've seen a card game that uses the Map API for the game interface. Pretty sweet.

As interesting as that would be, I'll have to read up on the map api, as I've never used it. Regardless, I will definitely look into this!

That feature already exists! http://dev.bukkit.org/server-mods/lagmeter/pages/configuration-info/

Look towards the bottom....

Or... How about use the underused Map API and have real time stats ;)

Shoot... put that map in an item frame for all players to see. That would be impressive

I can look into that in a day or two - right now, I've got a bugfix to release on one of my other plugins, code to reconstruct for the other, and a private plugin request to handle tomorrow and/or the next day.

I do know, however, that such a feature should be pretty easy to implement.

Also, as of late, my jenkins host has been having connection issues - which, if not resolved by the time I am ready and have implemented it (if able to), then I will just upload it to bukkitdev as a beta build, probably with a naming convention similar to bukkit, i.e. LagMeter 1.13.0-R0.1.

Love this plugin, just one criticism with it.

It would be great if you could type /lag 5 or /mem 5 to show the respective command 5 times, once per second, or however many times you wanted to see it. I tend to spam /mem four or five times to see the memory change really quickly over time, and it would be great to have a shortcut to it.

Keep doing great work!

Hm. I don't know what could be causing that; I can't reproduce it. Does it display the message to OPs?

@mal67

If your host says no, let me know.

I'm still not getting execution of commands on TPS and memory threshold using latest build #82. This is kinda crucial for keeping the server up ;-)

Help?

using spigot build 485

You'd need to ask your host to upgrade Java.
