   I am using pulsar 2.7.2 and Bookkeeper version is 4.12.0
   
   I am using the pulsar-perf tool for pulsar performance testing, and in the process I found that the read entry metric of the grafana panel Throughput(MB/s) has been zero
   
   By accessing the Bookkeeper metrics interface at http://Bookkeeper_IP:metrics_port/metrics it was found that the value of the BOOKIE_READ_BYTES metric has not changed. actually does produce and consume messages
   
   ***To Reproduce***
   
   Performance stress testing with the pulsar-perf tool, while producing and consuming messages
   
   ***Expected behavior***
   
   read entry is not zero

   pulsar has broker cache, can you show the broker cache miss metrics(pulsar_ml_cache_misses_throughput), if the cache miss metrics is 0, so bookie's read entry should be 0.
