@wildMythicWest I'm not sure I follow. You should do what the log message tells you: register the `MeterFilter` before meters would be registered to it through spectator.

fyi, here are the connected issues so far: - Vert.x: https://github.com/vert-x3/vertx-micrometer-metrics/issues/224 (cc: @sanyarnd) - KTOR: https://youtrack.jetbrains.com/issue/KTOR-7035/MicrometerMetrics-Prometheus-meter-registry-1.13.0-generates-configuration-warning (cc: @perracodex, @o-nix)

@wildMythicWest If I understand this correctly, in order to use the Spectator-Micrometer bridge, you need to setup things in this order: 1. Create a Micrometer MeterRegistry 2. Create and configure...

As far as I know it is only `@RestController` and `@Controller`. @jbotuck, we might need an issue/pr for Boot's repo to update this, do you want to create one?

Not much I guess. Since this is not available through JMX (like metrics for platform threads are), we need to utilize JFR and `jdk.VirtualThreadStart`/`jdk.VirtualThreadEnd` events (disabled by default) which might...

Could you please check if this feature could be useful for you: https://github.com/micrometer-metrics/micrometer/pull/4097?

It would be great if the instrumentation could live in Kafka, could you please let the Kafka team know you want this by leaving a comment here: https://issues.apache.org/jira/browse/KAFKA-15191

@vintagewang @YangJodie Could you please add no stale label?
