Monitoring the Queues

Monitor the shaper using Status > Queues to ensure that traffic shaping is working as intended. As can be seen in Figure Basic WAN Queues, this screen shows each queue listed by name, its current usage, and other related statistics.

Basic WAN Queues

Queue

The name of the traffic shaper queue.

Statistics

A graphical bar which shows how “full” this queue is.

PPS

The rate of queued data in packets per second (PPS)

Bandwidth

The rate of queued data in bits per second (e.g. Mbps, Kbps, bps).

Borrows

Borrows happen when a neighboring queue is not full and capacity is borrowed from there.

Suspends

The suspends counter indicates when a delay action happens. The suspends counter is only used with the CBQ scheduler and should be zero when other schedulers are in use.

Drops

Drops happen when traffic in a queue is dropped in favor of higher priority traffic. Drops are normal and this does not mean that a full connection is dropped, only a packet. Usually, one side of the connection will see that a packet was missed and then resend, often slowing down in the process to avoid future drops.

Length

The number of packets in the queue waiting to be transmitted, over the total size of the queue.
