Service Level Expectation (SLE)

Mist metrics measuring user experience against configurable thresholds, such as Time to Connect and Coverage.

Definition

Wireless SLEs include Time to Connect, Successful Connects, Coverage, Roaming, Throughput, Capacity, and AP Health. Each SLE breaks failures into classifiers that identify root causes, for example DHCP or authorization within Successful Connects. Thresholds are customizable.

Example

A Coverage SLE shows 92 percent success with the asymmetry classifier as the top issue.

Exam tip

Know which classifiers belong to which SLE.
