> There's good metrics for block manager (data dir) and WAL operations, like
> {{block_manager_total_bytes_written}}, {{block_manager_total_bytes_read}},
> {{log_bytes_logged }}, and the {{log_append_latency}} histogram. What we are
> missing are metrics about the amount of metadata I/O. It'd be nice to add
> * metadata_bytes_read
> * metadata_bytes_written
> * latency histograms for bytes read and bytes written
