MeowMC

/meow health

/meow health

Permission: bukkit.command.meowmc.health.

health is the one-page summary, rendered in the house monochrome style with one status rule: values that have a budget are green inside it and red outside it.

Per-world form

/meow health <world>

An argument narrows the page to one world (case-insensitive; tab completion lists world names): that level's Chunks, Entities and Players rows.

Per-world tick timing has no source in this build. The server-wide MSPT and TPS lines stay on the answer; a per-world timing figure is not rendered rather than a plausible-looking number without a source (worlds[].mspt is the report schema's documented null — see Report artifacts).

What the page shows

| Line | What it is | | --- | --- | | MSPT | Milliseconds per tick, with the tick budget in parentheses. | | TPS | TPS across five windows: 5s and 10s from the shared sampler, then 1m, 5m, 15m from the server's own long-window arrays — the same windows /tps renders. | | Memory | Heap used / heap max, plus direct memory used, and the direct cap when one is set. | | GC | Garbage collection as a fraction of wall time. | | Chunks / Entities | Loaded chunk and entity totals, summed across worlds. | | Threads | JVM thread count, plus the number of registered MeowMC thread pools. | | MeowMC … on 26.3 — … | The version line: the server's own reported version string, the Minecraft version, the JVM, core count. |

Memory 1.3 GB / 4.0 GB heap  direct 76 MB / 1.0 GB
GC 3.1% of wall time
Chunks 1402  Entities 2755
Threads 31 jvm, 6 registered pool(s)

Example output.

Rules worth knowing

  • The budget rule is the only colour. MSPT is green inside the tick budget and red past it; GC is green up to a tenth of wall time and red past that. Everything else is neutral — TPS is a reading, not a verdict, and the windows tell you the trend.
  • A cold server renders nominal readings. /meow report is the explicit alternative — its artifact nulls the sampler-sourced quantities on a cold server (see Report artifacts).
  • /meow tps — the same TPS readings rendered as bars.
  • /meow report — the same surface, written to a JSON artifact.
  • /meow perfhud — the in-game HUD that renders the sampler continuously, per player.
