Confusing metrics for HBase in Cloudera Manager

Hi,

 

I was digging in the HBase metrics available in Cloudera Manager and I can't really understand the differences between the following metrics:

 

  • total_read_requests_rate_across_regionservers, total_write_requests_rate_across_regionservers (from the service home page) lists: 18000 req/s for reads - 100 req/s for writes
  • total_requests_rate_across_regionservers (from the charts library): lists something like 1000 req/sec

Given the names I was expecting something like: total_requests = total_read_requests + total_write_requests but this is clearly not the case.

 

Which metric reflects the actual load of the HBase cluster?

 

Thanks,

parnigot.
