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Some of them are a little out of date, but you get the idea.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

Yes, but I did say that I have never executed a command from a plugin before. I will try to fix it, but it may take time and lots of googling.

I'm guessing the reason they sometimes show up is because the interval at which the plugin checks to see if the tps/mem is low is configurable, defaulting to I think 5 minutes for tps, 10 for memory.

Some work, some don't work correctly, and some just don't work at all.
That's what a dev build is. You can read above in the main post, it forewarns that they are not always completely tested, or sometimes, tested at all.
If you need it to work, use a recommended build - they're always on this BukkitDev page and I promote them to "recommended" on my jenkins.
@andrewkm
Will attempt to fix when I return from my nephews' elementary school (picking them up).

Ok, two things...
First: are the low tps warnings showing up? I'm not sure if I tested this.
Second: Try adding a slash to the beginning. I'm not sure if I hardcoded one in. It could easily just be my code, though. I've never forced a command from a plugin before, so I may have failed on that account.

I tried fixing it and my test server decided to spam its console until it died. That was a derp moment because I forgot to change something.
Now, after changing that, it's fixed and pushed to github.

Oops, made Vault a hard depend instead of soft. Hold on.
Edit: or not... dunno what's wrong.
Edit 2: Nevermind, I know what's wrong. Pushing to github, it'll build on jenkins again in 15mins or less.

Posted Sep 10, 2012It's about finished, and I'm about to push to GitHub, which means it should automatically build on my Jenkins server within the next 15-20 minutes. Be warned I have done little QA on this, so it may not work.
In fact, I kind of doubt it to work.
Configs: Notifications: Lag: Enabled: true Threshold: 17 CheckInterval: 5 ConsoleCommand: lag Memory: Enabled: true Threshold: 25 CheckInterval: 10 ConsoleCommand: mem
Note that memory is memory free, not memory used.

Posted Sep 10, 2012No, but today is LagMeter day - I cleaned up the code yesterday, now it's time to work on it. I do have to go get my nephews shortly, though, so when I return, I will begin work on it.
