Mist AI Dashboard: Insightful SLEs
Steep declines and deviations
in the throughput graph
indicate that something is
wrong.
Only 34% of users
are having a good
user experience.
Issues that may be
contributing to the poor user
experience include Latency &
Packet Loss.

A transient congestion has occurred
and has therefore triggered a
downward trend in the WAN Link
Health SLE.
Root Causes Analysis indicates that
Latency and Jitter values are
contributing to a sub-par user
experience.
