Issue/Introduction

The SD-WAN Tunnel (Card) View on the  runs for 6-8+ minutes before completion.

The DX NetOps Portal default SD-WAN Tunnel (Card) View on the default SD-WAN Tunnel Statistics Dashboard runs for 6-8+ minutes before completion.

This is seen for all Site Groups. The larger the Site the longer the View takes to render and complete.

Environment

All supported DX NetOps Performance Management Portal releases 22.2.6 and newer.

Cause

Starting with 22.2.6 we began including Tunnels that don't have data. They appear as the Gray circle tunnel count showing a No Data label as seen here.

When large numbers of tunnels are involved, in this instance more than 40,000 tunnels and growing, it creates an efficiency issue causing the query the report uses to run for longer than anticipated.

Resolution

1) The view will be faster on smaller sites

2) A control has been added to the view configuration: "Include Missing Item Inventory". Disabling this can speed up the views. if you need to use on larger sites.
