Use federated collectors in Virtualization Manager
The federated collector serves as a proxy. It collects configuration and performance data, and sends the data back to SolarWinds Virtualization Manager. To monitor 10 000 VMs or more, using a federated collector is strongly recommended.
A single SolarWinds Virtualization Manager data collector might not have enough computing resources to collect data from large virtual environments with thousands of VMs. If you experience slow performance due to collection, consider deploying a federated collector.
Additionally, it is more efficient to collect data from distant vCenters by using a federated collector in that location and having the collector periodically connect to Virtualization Manager with the collected data. If you use WANs, consider deploying a federated collector.
To use federated collectors, TCP port 61616 must be open on SolarWinds Virtualization Manager. For more information, see VMAN port requirements.
