Attachment: CASSANDRA-11569v2.txt
> Track message latency across DCs
> --------------------------------

> Key: CASSANDRA-11569
> URL: https://issues.apache.org/jira/browse/CASSANDRA-11569
> Project: Cassandra
> Issue Type: Improvement
> Components: Observability
> Reporter: Chris Lohfink
> Assignee: Chris Lohfink
> Priority: Minor
> Attachments: CASSANDRA-11569.patch, CASSANDRA-11569v2.txt

>
> Since we have the timestamp a message is created and when arrives, we can get
> an approximate time it took relatively easy and would remove necessity for
> more complex hacks to determine latency between DCs.
> Although is not going to be very meaningful when ntp is not setup, it is
> pretty common to have NTP setup and even with clock drift nothing is really
> hurt except the metric becoming whacky.
