Collecting Data Using the insync and repldisc Commands

Use the output of the insync and repldisc commands to help troubleshoot your replication divergence.

The insync command indicates the state of synchronization between a master replica and one or more consumer replicas and can help you identify bottlenecks. If you are troubleshooting a problem with replication divergence, this data must be periodic. For more information, see Using the insync Command.

If you identify a bottleneck using the insync command, for example a bottleneck that results from an increasing delay as reported by the tool, it is helpful to start collecting nsds50ruv and ds6ruv attribute data. This data can help you identify when and where the potential halt is taking place. For more information about the nsds50ruv and ds6ruv attributes, see About Replica Update Vectors (RUVs).

The repldisc command displays the replication topology, building a graph of all known replicas, then showing the results as a matrix. For more information, see Using the repldisc Command.
