Hi, We have multi DC Cassandra ring with 2 DCs setup. We use LOCAL_QUORUM for writes and reads. The network we have seen between the DC is sometimes flaky lasting few minutes to few 10 of minutes.
I wanted to know what is the best way to measure/monitor either the lag or replication latency between the data centers. Are there any metrics I can monitor to find the backlog of data that needs to be transferred? Thanks in advance. VR
