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Some of them are a little out of date, but you get the idea.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

Posted Mar 18, 2014Hello, recently I've been lagging a TON on my server and a lot on other servers. I installed this plugin (love it, by the way. Great job!) and I did /ping. It says:
[LagMeter] Average response time for the server for 1 ping hop(s) to (insert my IP address here): 78.556
My questions are 1- Is the higher number better or...? 2- Is that a good connection to the server? 3- Little off topic from the plugin but is that mean my connection to the server is bad or do I lag out because of my internet just being bad in general? (my ISP said to check my ping from my ISP to the server. If it's slow connection to the server it's bad but if my connection to my ISP is bad it's my ISP's issue..) ?

I can't reproduce this bug in any way, no matter what I try. Care to shed some light on what you're doing, perhaps your configuration?

Unfortunately, there isn't a way for me to access that information from the API interface, then display it in a real-time manner. If you type /timings into your server console (I don't remember the full command - try typing /timings then pressing tab and it should tell you), let it run for a while then paste the log it generates here: http://www.aikar.co/timings.php then it'll tell you what's taking the longest to process on your server.

Posted Nov 12, 2013Hey i have a question, will this plugin also see what cause the lagg ? Because im playing on a server that had just a hardware update (i7 CPU, SSD, 32GB ram) but since the update (same time 1.6.4 got released) server got nasty lag/rollbacks of 2 a 3 seconds every 30 seconds. Also server got moved to a different location. (from France to USA)
Is there any way we can find the problem of these laggs/rollbacks ?
Been searching on google for a while now but this looks most promised to me :)
edit: before update server runs smoothly with around 150 players, now with even 1 player online this lag is still here.

There are updates coming, hopefully soon. I've been working on pushing to LagMeter's repository for a while, but I recently became swamped with coursework for school, so I haven't really had time to do a whole ton.

No worries thanks for the awesome plugin! I figured out it would probably be percentage since I set it to 400 it would run the command at the first chance it would get lol.

It should be a value based on the percentage of memory free. So it'd be 4 or 5 in your case. Sorry for the confusion.

Posted Oct 20, 2013Hello, for free memory threshold what does the value represent? I set it to 400 thinking it would run the commands if the server went under 400mb free memory but it would run the command at around 9gb's free memory so I believe I'm using it wrong lol.
Thanks in advanced.
