Testing Individual Nodes

To check that each back-end node in a pool can receive requests from the Virtual Traffic Manager, switch the load-balancing algorithm for the pool to “Round Robin” (see Load Balancing). The Round Robin load-balancing algorithm routes requests to each node in turn; you can use the logs on your back-end servers to check that this is working for every node.

You can also configure nodes to drain connections (see Draining, Disabling, or Removing a Node). If you have several nodes in a pool, you can temporarily stop the Virtual Traffic Manager sending traffic to some by setting them to drain. To test each node in turn, you can drain all the nodes apart from the one you wish to test.

Enable server logging on each node and verify that the logs the nodes write are consistent with the activity on the system.
