High data transfer from targets to monitoring server

We have just deployed SQL Sentry into our environment and we are seeing high amounts of data sent from the monitored targets to the monitoring server. Averaging 10GB sent from each target to the monitoring server over 24 hour period. Is this normal?

we have almost 50 monitored targets and we’re seeing almost 500GB being sent over the network to the monitoring servers. The database is not growing at anywhere near this rate, so where’s all that data going?

We’ve increased some of the polling rates but still seeing high data transfers
