LagMeter
![](http://dev.bukkit.org/thumbman/images/45/120/600x99/logo.png.-m1.png)
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.Tutorials and Reviews
Some of them are a little out of date, but you get the idea.
Download
CI/build (Jenkins) serverYou 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.

192 blows up on my console after a few minutes. Same as the version the other day. 1.31 Server 2008R2 32 gigs ram, Ivy bridge
Fixed. Uploading.
I'm having the same issue as SavageCore. Worked fine before we updated to 1.9.0.
You're probably already aware of this, but http://pastebin.com/J7NbLZAk
You should be able to disable the logs folder feature. Try adding useLogsFolder: false under the already-existing log category. If that doesn't work, try capitalizing the 'u' in 'use'. I can't check right now; I'm on a machine that doesn't have my code on it. I'll fix this later tonight.
I also get null\logs created in root dir instead of /plugins/lagmeter/logs
@TnTBass
The NPE is from the server being unable to create a logfile. As for the inability to create a logfile, you probably need to give the current user you're using for the server the read/write/create permissions for the plugins folder. I'll toy with this some and see if I can find a solution.
My findings as well... on Linux:
2012-08-07 18:07:34 [INFO] [LagMeter 1.9.0] Enabled! Polling every 40 server ticks. Logging to /home/minecraft/bukkit/plugins/LagMeter\logs/lag08-07-2012.log
Maybe it doesn't like the backwards \ before logs? It also created a directory named "null\logs":
[minecraft@minecraft bukkit]# ls -l ... drwxrwxr-x. 2 minecraft minecraft 4096 Aug 7 17:51 null\logs
@TnTBass
Same as for me. But the plugin works just fine ;)
@TheLunarFrog
If the logs folder doesn't exist, it kicks up an error:

Using Lagmeter 1.9.0
Edit: Scratch that, created the "logs" folder, still got an error:
http://pastebin.com/KCEUtBBQ
Edit #2:
Found this on my console when I came back later (most likely due to the logs folder issue):
http://pastebin.com/aamHPwUY
None of this is at all a big deal, just wanted to share my findings. :)
@Kemren
I don't think it's implemented in the current version yet.
Ooh, there's an alert thing already? How do I turn it on? =D
@Kemren
The alert thing is already done, but I'm currently trying to juggle this with many, many other things, such as moving house, schooling, other plugins, etc. and I have to fix an exception that's caused every time LagMeter logs.
As for the average thing, we'll see. LagMeter actually has something that could be used for this already, so I might be able to implement that.
Ooh, it might also be cool if the plugin recorded every 5th or 10th cycle into a a log, that way you could check the lagmeter log to see how the server's performance has been. Maybe it could even average them to give you an average "Server Lag" reading that might be low on servers that are lagging way too much?
I know, the update might turn into quite a project if you tried to include that, but i still think it'd be cool.
Could use an update. Not because it's actually malfunctioning, but simply to get that alert thing implemented. I love that idea.
Preferably have it be by permission. So that only people with lagmeter.alert can see the alert, or something like that. =)
@MrPiggy54
What do you mean? If you want a little button that fixes all the server's lag, you're living in a fantasy world. The plugin is as described.
does this clear lag?
