Location AP Health SLE
SUMMARY Use the Location AP Health SLE to identify location issues caused by access points that rebooted or lost connectivity to the cloud.
Location AP Health is one of the Location Service-Level Expectations (SLEs) that you can track on the Monitor page of the Juniper Mist™ portal. Understand what's measured by this SLE and what issues can contribute to a low SLE.
What Does the Location AP Health SLE Measure?
Juniper Mist counts the incidents when APs rebooted or lost connectivity to the cloud.
You can click the Settings button to set the number of incidents to allow as the success threshold for this SLE.
Classifiers for Low AP Health
When the number of incidents exceeds the threshold for this SLE, Juniper Mist classifies the issues as follows.
-
Low Power—The AP had insufficient power.
-
AP Disconnected—The AP had insufficient power.
-
Ethernet—The AP lost Ethernet connectivity.
Example
-
Success Rate—On the left, you see that the Location AP Health SLE threshold was met 93 percent of the time.
-
Timeline—In the middle, you can drag your mouse to explore this SLE over time. In this example, the success rate was 83 percent at the selected moment. To adjust the scope of the timeline, use the timeline drop-down list at the top of the Monitor page. For example, set the timeline to Today, Yesterday, This Week, or a custom date range.
-
Classifiers—On the right, you see a high-level root cause analysis for the incidents that failed to meet the threshold. Most (65 percent) were attributed to low power. The remaining issues were attributed to Ethernet (31 percent) and AP Disconnected (4 percent).
You can click the Values button to show numbers instead of the success rate and classifier percentages. On the left, you see that there were 1371 incidents. In the middle, you see that there were 20.0 incidents at the selected moment. On the right, you see the number of user minutes that were attributed to each classifier.
