About this Mod
why?
Too lazy to type /spark tps && /spark gc every time I wanted to check server health, so now it just sits on the BetterF3 screen
BetterF3 - Spark Module adds one more module to BetterF3's screen: live TPS, MSPT, CPU and GC stats, read straight from spark
What you get
| Line | Shows |
|---|---|
| TPS | 5s, 10s, 1m, 5m, 15m averages |
| MSPT | mean + 95th percentile tick time (10s window) |
| GC Young | avg pause / frequency - the normal small collections, happens constantly, nothing to worry about |
| GC Full | avg pause / frequency - full GC, G1 tries hard to avoid these. |
| GC Concurrent | avg pause / frequency - background marking work, runs alongside the game without stopping it |
| CPU | this client's own process/system load |
Config
No separate config - it's just another BetterF3 module. Open F3+M (needs Cloth Config, same as any BetterF3 module) to toggle it, move it, or recolor individual lines.
Server && LAN
Hosting your own world (singleplayer or LAN)? Just works, no setup.
Playing on someone else's server is different if you want real numbers instead of a "not installed on server" placeholder, the server owner needs this same jar (+ spark) on the server too. No config involved, it just starts broadcasting once both sides have it.
Why does the server need this too?
Spark only ever reports on the machine it's running on. As a normal player, that machine is the server's, not yours - your client can't see into it unless something on that end shares the data. This addon is that something.
License
MIT. It reads data through spark's MIT-licensed spark-api, and displays it through BetterF3's public module API - both used as intended, nothing bundled from either.
