THIS IS A TEST INSTANCE. ALL YOUR CHANGES WILL BE LOST!!!!

The following new metrics will be added:
| mbean | description |
|---|---|
| kafka.log.remote:type=RemoteLogReaderMetrics, name=RequestsPerSec, topic=([-.w]+) | Number of remote storage read requests per second. |
| kafka.log.remote:type=RemoteLogReaderMetrics, name=BytesPerSec, topic=([-.w]+) | Number of bytes read from remote storage per second. |
| kafka.log.remote:type=RemoteLogReaderMetrics, name=ErrorsPerSec | Number of remote storage read errors per second. |
| kafka.log.remote:type=RemoteStorageThreadPool, name=RemoteLogReaderTaskQueueSize | Number of remote storage read tasks pending for execution. |
| kafka.log.remote:type=RemoteStorageThreadPool, name=RemoteLogReaderAvgIdlePercent | Average idle percent of the remote storage reader thread pool. |
| kafka.log.remote:type=RemoteLogManagerMetrics, name=RemoteLogManagerTasksAvgIdlePercent | Average idle percent of RemoteLogManager thread pool. |
kafka.log.remote:type=RemoteLogManagerMetrics, name=CopyToRemoteStorageBytesPerSec | Number of bytes copied to remote storage per second. |
| kafka.log.remote:type=RemoteLogManagerMetrics, name=CopyToRemoteStorageErrorsPerSec, topic=([-.w]+) | Number of remote storage write errors per second. |
| kafka.log.remote:type=RemoteLogManagerMetrics, name=CopyToRemoteStorageBacklogBytes | The total number of bytes of the segments that are pending to be copied to remote storage. |
Performance Test Results
We have tested the performance of the initial implementation of this proposal.
