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

["T Jake Luciani (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/CASSANDRA-8702?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14296881#comment-14296881 ] 

T Jake Luciani commented on CASSANDRA-8702:
-------------------------------------------

I see in JMX and nodetool cfstats these are all micros.  Even your message above looks like micros...

What are you expecting to see? and how did you generate the above message?

> 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:

> WriteLatency

> Count: 1

> Max: 379.022
> WriteTotalLatency
> -----------------
> Count: 339667
> {code}
> In LatencyMetrics:
> {code}
>     /** Total latency in micro sec */
>     public final Counter totalLatency;
> {code}
