-----------------------------------------
Summary: 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
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.
