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Some of them are a little out of date, but you get the idea.

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.

Sure there is. I don't believe essentials gives you the option to not average the TPS out. Along with that, this allows you to run commands when the TPS or mem run low (and will also say so in console, as well as tell every OP who is online or has the permission node required to see it), such as forcing a server restart. It also has logging of TPS, memory usage, and players, at a configurable interval.

All of these features can be turned on or off, as well.

@ronfkingswanson

I will look into this as soon as I can. When I tested it, it worked...

Fixed in next snapshot.

@Maximvdw

That doesn't work for me, are you using CraftBukkit as your dependency?

@Intangir

@ronfkingswanson

Tried fixing it, still looking for a way to actually fix it.

after using the 1.12 snapshots for so long, I've been loving the execution of commands on TPS and memory drop - but the 1.12 release isn't running those same commands:

Notifications: Lag: Enabled: true Threshold: 7 CheckInterval: 1 ConsoleCommand: /stop

Ansi.ansi().fg(Ansi.Color.BLUE).boldOff().toString()

should also add color to the console (example for blue)

What I meant was, make it look like a chat GUI. Very neat and clean. For example, Towny's /town command brings up a nice clean GUI in chat. The re-coloring fits in with that.

Change the wording? To what? It's not like there's a whole lot of text in LagMeter. And the colouring is fine, in my opinion.

To fulfill any suggestion, I need an actual suggestion, not "change wording, add colour."

Any way to get rid of the entities and chunks loaded in each world? Seems obvious but super annoying.

Getting the old HDD out of that computer is going to take time, so I'll just try to remember what I did locally but didn't push and start updating from there. First up: no longer is vault required for LagMeter (dev build).

Ok, so development has been on a freeze for a bit for LagMeter. There's a reason, or well, several reasons:

First, I ordered parts for a new computer, which I just assembled a day or two ago.

A while before those parts got here, my power supply for my old computer exploded. Couldn't use that computer anymore. Guess where all of the source code is? There.

Now that my new computer is assembled, I have to put the old HDD in my new computer, which shouldn't take long. But this week was midterm exam week, which is why it didn't happen.

@JAG100

There should be a dev build that gets rid of the formatting. As for overriding, you'd have to ask NoLagg's dev to add config node where you can disable commands.

Running Spigot latest release. Noticed some strange symbols that I recognize as color formatting but in my console and in the log file it just looks like this:

[LagMeter 1.11.1] §a§f[§a####§f§f] 20.0 TPS

[LagMeter 1.11.1] §a§f[§a####§f§f] 5992.0MB/6886.0MB (87%) free

Also, I run ClearLag plugin and it used the "lagg" command. Small matter as one can always just type "lm" into the console to get both lagg and memory. Would be something worth maybe adding in config to customize?

Looking forward to using this plugin!

Best, JAG
