Similar to Web Application Health, WAN Health is designed to monitor the performance of WAN uplinks across multiple sites and provide additional insights into detected performance issues for general WAN connectivity. By selecting one of multiple, custom configurable, publicly accessible endpoints on the WAN, information such as total usage, loss, average latency, jitter, and more are directly available for every WAN uplink across all participating sites (see Figure 5-20). This provides a great starting point when you’re looking into reported connectivity issues for different sites and enables you to easily pinpoint when the cause of unexpected connectivity behavior is due to a remote or upstream issue.

VoIP Health
VoIP Health is similar to WAN Health in that it is configured to monitor specific, custom endpoints and provide reporting related to the quality of connections to each endpoint. However, unlike WAN Health, which is intended to monitor generic, publicly accessible endpoints to report on general uplink connectivity and health, VoIP Health is intended to monitor connections to specific VoIP endpoints, either public or private, to provide more detailed data specific to the paths used by critical VoIP traffic.
As a result, the data provided by VoIP Health (see Figure 5-21) is specifically tailored to VoIP applications and troubleshooting. Information such as the path MOS, loss, latency, and jitter is at the forefront of reported data to directly assist in monitoring and troubleshooting VoIP-related behaviors.

Insight Alerts
As part of the monitoring solution for Meraki Insight, you can configure specific alerts such as those based on application performance thresholds, WAN utilization, uplink status changes, packet loss, latency, MOS, and more. For alerts based on application performance thresholds, you configure per-application alert settings by navigating to the Insight > Web App Health > Manage Alerts page on the Dashboard.
For other alerts such as WAN Health or VoIP Health alerts, go to the Insight > Insight Alerts page. Insight Alerts are discussed in more detail in Chapter 2 as well as in the documentation online at https://documentation.meraki.com.
Configuring these alerts and their respective alert thresholds appropriately can serve to provide critical information as soon as unexpected behavior begins to appear. This helps to initiate the troubleshooting process faster and more efficiently by providing important details about the nature of the behavior and potential causes alongside the initial report, making resolution times shorter and improving the efficiency of your IT teams.
