Application Performance

Monitoring > Performance > Application Summary

This tab displays application performance data for up to 50 applications. It reflects a real-time measure of latency per flow. The Application Performance column displays latency measures for Client Network Delay (orange), which is from the EdgeConnect to the client-side of the flow, and for Server Network Delay (blue), which is from the EdgeConnect to the server-side of the flow.

Latency is calculated using three different metrics. Each of these metrics are reflected on the Application Performance tab:

  • Client Network Delay (CND)

    • Represents the latency measured between the client and the EdgeConnect branch.

    • Corresponds to “Network to Client Delay (CND)” data on flow details.

  • Server Network Delay (SND)

    • Represents the latency measured between the EdgeConnect hub and a server.

    • Corresponds to “Network to Server Delay (SND)” data on flow details.

  • Total Network Delay

    • Represents the total latency measured.
      Client Network Delay + Server Network Delay = Total Network Delay

    • Corresponds to “Client to Server Response Delay (Total Delay)” data on flow details.

The latency metrics displayed on the Application Performance tab are taken from the flow details for each flow. To view flow details, go to Monitoring > Flows > Active & Recent Flows, then click the info icon for any flow, and click Performance to view application performance data.

The Client Network Delay and Server Network Delay metrics differ when you’re viewing data for an EdgeConnect at a branch versus data for an EdgeConnect at a hub that connects to a server.

When viewing data for an EdgeConnect at a branch, the Client Network Delay (orange) represents a smaller portion of the total delay. The graphic below depicts how each metric is measured for an EdgeConnect at a branch.

When viewing data for an EdgeConnect at a hub, the Client Network Delay (orange) represents a larger portion of the total delay. The graphic below depicts how each metric is measured for an EdgeConnect at a hub.

To view latency trends for an application over time, click the Historical Charts icon. The Application Trends tab opens and displays a chart for the application.
