In the Juniper Mist dashboard,Service Level Expectations (SLEs)are metrics that measure user experience in key areas such as connection, throughput, and roaming. Each SLE is composed ofclassifiers, which help identify the underlying cause of degraded performance or sub-threshold scores.
According to the Juniper Mist AI documentation, theRoaming SLEtracks client transitions between access points and evaluates the quality of those roaming events. The contributing classifiers typically includeSignal Quality,Wi-Fi Interference,Ethernet, andCapacity.
In this exhibit, the bar forCapacityis the longest under the “Roaming Classifiers” section, indicating that it has the most significant impact on theSub-ThresholdSLE value (10.6%). This means roaming performance is primarily being limited by insufficient capacity — often due to AP radio congestion or a high number of concurrent clients impacting handoff efficiency.
Hence, theCapacityclassifier is responsible for the sub-threshold SLEs.
