Statistics->Subscribers->Metrics gives accessto several metrics per subscriber. Several subscribers are listed. If the subscriber of interest is not listed, type the IP address on the filter field.

The most recent metrics are shown for each subscriber (flows, traffic usage, latencies, retransmissions, etc.).

A click on a metric value leads to a chart with historical data up to three months. For example, clicking on CURR-MB leads to a chart of traffic throughput over time.

A very useful metric to monitor the quality experienced by a subscriber is the maximum downlink speed measured over a time window:

‍

To investigate possible quality issues, the Subscriber latency metrics show the access latency experienced by the subscriber compared with the average access latency for the whole network:

Also the access retransmission percentage can be obtained, with the network average as a reference:

Finally, we can also see the number of active flows and the number of flows created per subscriber in a 5-minute window, which can point to virus/attack problems or to subscribers reselling their connection to other users:
