Data Movement Replication operations

Data Movement: Replication operations

This statistic tracks Replication read and write operations performed by the Replication service.

When to check

When investigating Replication activity.

Breakdowns

Breakdown
Description
direction
Shows IO operations broken down by direction, to or from the appliance.
type of operation
Shows IO operations broken down by type of operation with the remote appliance, read or write.
peer
Shows IO operations broken down by the name of the remote appliances.
pool name
Shows IO operations broken down by the name of the pools.
project
Shows IO operations broken down by the name of the projects.
dataset
Shows IO operations broken down by the name of the shares.
latency
Measures the current network latency experienced during replication data transfer.
offset
Measures the offset in all replication transfers relative to the start of each individual replication update.
size
Measures the read/write operations size performed by replication service.
as a raw statistic
Shows IO operations as raw statistics.
