    BedrockConnect

    BedrockConnect

    Join any Minecraft Bedrock Edition server IP on Xbox One

    On Minecraft Bedrock Edition, players on Xbox One, Nintendo Switch, and PS4/PS5 are limited to playing on 'Featured Servers' approved by Mojang/Microsoft. These players are not able to join servers via an IP/address. This is an issue for me and others, as the server community on Java edition was one of the major parts that made Minecraft what it was, and what also made the servers that are now considered 'Mojang Server Partners' what they are today. I wanted to fix this, so I made a solution that anyone can set up easily.

    JMX Exporter

    JMX Exporter

    A process for exposing JMX Beans via HTTP for Prometheus consumption

    JMX to Prometheus exporter: a collector that can configurable scrape and expose mBeans of a JMX target. This exporter is intended to be run as a Java Agent, exposing a HTTP server and serving metrics of the local JVM. It can be also run as a standalone HTTP server and scrape remote JMX targets, but this has various disadvantages, such as being harder to configure and being unable to expose process metrics (e.g., memory and CPU usage). Running the exporter as a Java agent is strongly encouraged.
