Local Rate: Plots the per-node rate and the aggregate across the nodes at the site. The top line is the sum, each other line corresponds to a single node.
Local Limit: This plots the local rate limit of each node (using a token bucket) and the sum of the limits (the top line).
Weight: The FPS weight value at each node. When the aggregate traffic rate is at or above the global rate limit, each node shares a portion of the global limit according to its weight value. For instance, if there are two nodes with weights of 9 and 3, the first node will be assigned 3/4 (9/12) of the global limit, while the second node will receive 1/4 (3/12).
# of Flows: A count of the number of active flows at each node.
Average Flow Rate: The mean flow rate at each node.
