Add Milliseconds Per Tick to gathered performance metrics

[AuroraLS3]

I would like to be able to..

MSPT is another metric that can be used to measure performance in addition to TPS.
It might be interesting to see that over time.

Is your feature request related to a problem? Please describe.

MSPT and TPS are heavily linked as one tick has at most 50ms to perform tasks. If users can monitor this metric they will have a better idea if they have an appropriate amount of resources allocated when MSPT is far below 50ms.

MinecraftServer has a field that stores this information and some of the server platforms expose it directly.

TabTPS is a plugin with MIT license that can be used for looking how to access it on Paper, Spigot, Sponge and Fabric.
For Nukkit the current diff calculation in TPS gathering task can be used to get some idea of MSPT.

That's all 4 game server platforms Plan supports.

Agreed. ms/tick is much much more useful than TPS

TSP is a "if its useful its already too late" kinda metric. My server runs on 20 TPS most of the time but I want to see at what time mspt is highest and with what it correlates. TPS is forking useless for that. I have to resort to spark profiler but that goes only back 60 minutes :(

Hello,
I confirm that tps are not useful at all, because 1 or 49 mspt you'll have 20tps, so you can't measure your real performances.

It's good to know your MSPT (avg/95%ile) to compare when you did changes and other things !

If you would like to help me test this feature please download the dev build in https://github.com/plan-player-analytics/Plan/actions/runs/17268867945 and send a comment saying if the data is appearing few minutes after boot and what platform/version are you running.

The data should be visible under Performance > TPS graph:

If it is not working MSPT Average will say 'Unavailable'

Check #4243 to see which servers have already been tested

Nukkit implementation was skipped.

Hello,
I'm trying this next server restart on paper 1.20.4, TY !

[WarnDa]

I don't get MSPT, it says "unavailable", here is my versions of everything :

Universpigot is a paid paper fork for big server but it runs like vanilla, no behavior change on it, and every plugin I got (>100) are compatible.

[AuroraLS3]

That's what I expected in some cases.. The implementation on bukkit/spigot/paper relies on reflection to access the field with the data inside MinecraftServer class and where that is located varies wildly with versions

Thanks for testing it out
