TPS, chunk load, memory, and player telemetry — live across every server you run.
What it stores
Connected RCore servers send player counts and a 1-minute TPS average every five minutes by default. Other server metrics are stored when supplied in a statistics batch. Vanilla player statistics are stored when pushed. Received data stays in the database without a scheduled expiration.

FeatureQuestions
Connected RCore servers send player counts and a 1-minute TPS average every five minutes by default. The API also stores 5- and 15-minute TPS, memory, CPU, chunks, entities, tile entities, and uptime when supplied in a statistics batch. Vanilla player statistics are stored when pushed. Received records and aggregates have no automatic expiration.
Install RCore and start the server once. Set central.apiKey in plugins/RCore/config.yml, restart, then run /rcore connect in game as the linked Minecraft player. Keep the key out of chat.
Paper and Spigot on Minecraft 1.16.5 through 1.21. Purpur works. Folia does not — per-region tick threading breaks the tick collector.
No measurable impact under normal operation. The collector runs off the main thread and batches metrics before sending. Benchmark results are published in the docs.
