[jira] [Created] (CASSANDRA-8702) LatencyMetrics is reporting total latency in nanoseconds rather than microseconds

Mike Adamson created CASSANDRA-8702:
---------------------------------------

             Summary: LatencyMetrics is reporting total latency in nanoseconds rather than microseconds 
                 Key: CASSANDRA-8702
                 URL: https://issues.apache.org/jira/browse/CASSANDRA-8702
             Project: Cassandra
          Issue Type: Bug
            Reporter: Mike Adamson


I don't know if this is the desired behaviour but all the comments in the code indicate that it should be reporting microseconds. 

A single write shows the following:
{code}
WriteLatency
------------
Count: 1
Min: 315.853
Max: 379.022

WriteTotalLatency
-----------------
Count: 339667
{code}
In LatencyMetrics:
{code}
    /** Total latency in micro sec */
    public final Counter totalLatency;
{code}
