Real-Time Traffic Analytics & Flow Monitoring

Objective

Demonstrate live visibility at both the Director (global) and device (z40) level by verifying:

  • Real-time bandwidth by edge controller and per-client
  • Live Top Applications / Domains
  • Live per-interface rates/counters on the device
  • Event/log correlation during live traffic changes
  • Time-range and auto-refresh behavior for live views

Prerequisites

  • One z40 onboarded to the cloud Director; tunnels up to the cloud vGR
  • At least one LAN client connected on LAN00 (via switch is fine)
  • Admin access to Director
  • Ability to generate traffic on the LAN client (web browsing, a Microsoft Teams call, file download, or iperf)

Test 1 — Global dashboards live window & auto-refresh

Setup

  1. In Director, navigate to Analytics → Dashboards (global).
  2. Use the time control to set a short live window (e.g., Last 15 minutes).
  3. Enable auto-refresh (choose an interval and click Start).

Steps

  • Begin traffic on the LAN client (e.g., start a Teams call or a file download).
  • Observe tiles/graphs updating without manual page reloads.
  • Change the time range (e.g., Last 30 minutes) and confirm the views rescale immediately.

Validation

  • Charts/tiles refresh and reflect traffic starting/stopping within the live window.
  • Auto-refresh updates the view on the chosen interval.

Evidence

  • Global dashboard showing the selected time window and visible change in widgets while traffic is active.

Test 2 — Top Applications / Domains (global)

Setup

  1. From Analytics → Dashboards, open Top Apps/Domains.
  2. If a device selector is present, filter to the z40.

Steps

  • Start one identifiable application on the LAN client (e.g., Teams or YouTube).
  • Let it run for ~1–2 minutes, then stop it.

Validation

  • While running, that app rises in Top Applications; when stopped, its contribution drops within the current live window.

Evidence

  • Top Apps/Domains view clearly showing the application’s rise during the test and its decrease after stopping.

Test 3 — Bandwidth views under Overview (global)

Setup

  1. In Analytics → Dashboards, open Overview.
  2. Within Overview, use these views (as tabs/cards in that area):
    • Edge Controller – bandwidth
    • Client/LAN PC bandwidth
    • Network overview (optional, estate-level)

Steps

  • With traffic active, watch Edge Controller – bandwidth for the z40 move up.
  • Open Client/LAN PC bandwidth and identify the LAN client by hostname/IP.
  • Pause traffic briefly, then resume with a different activity (e.g., switch from video to a file download).

Validation

  • The z40’s bandwidth rises/falls with traffic changes.
  • The client entry mirrors the LAN host’s behavior (download/upload swings).
  • Network overview (if used) trends coherently with the other two.

Evidence

  • Captures of the Edge Controller – bandwidth and Client/LAN PC bandwidth views showing changes corresponding to the traffic actions.

Test 4 — Device live counters (Interfaces)

Setup

  1. Navigate to Edge Controllers → [z40] → Analytics → Statistics.
  2. Open the Interfaces tab.

Steps

  • While the LAN client is driving traffic, observe TX/RX rates and pps on expected interfaces (e.g., WAN00LAN00).
  • Stop the traffic, then restart it, watching the counters respond in near-real time.

Validation

  • Interface rates/counters rise when traffic starts and drop when it stops.
  • The interfaces carrying traffic align with the global bandwidth views from Test 3.

Evidence

  • Interfaces view showing rate/counter movement in sync with traffic changes.

Test 5 — Live event/log correlation

Setup

  1. Still under Edge Controllers → [z40] → Analytics → Statistics, open Logs and Events.

Steps

  • Trigger a brief, controlled event during a quiet moment (e.g., toggle a non-primary WAN link or momentarily disable/enable a test tunnel if safe in your lab).
  • Keep the LAN client traffic running while you do this.

Validation

  • A corresponding entry appears promptly in Logs and Events (e.g., link/tunnel down → up) with timestamps in your live window.
  • Global throughput views remain coherent (brief dip/spike is explainable by the event timing).

Evidence

  • Logs and Events view showing the event tied to your action and matching timestamps with observed traffic behavior.

Test 6 — Cross-validation: Top-app vs interface

Setup

  • Keep Top Apps/Domains (global) open in one tab and the Interfaces tab (device) open in another.

Steps

  • Drive exactly one app (e.g., initiate a Teams call only).
  • Observe which interface carries most traffic on the device view.
  • Confirm Top Apps/Domains highlights the same application during the same time window.
  • Switch to a different activity (e.g., stop the call and start a file download) and repeat the observation.

Validation

  • The top application shown globally corresponds to the interface bearing the traffic on the device.
  • Changing the application mix flips both the top-app view and the interface distribution accordingly.

Evidence

  • Paired captures demonstrating consistency between Top Apps/Domains and Interfaces for the same short window.

Negative / Edge checks (live)

  • No traffic: with the LAN client idle, confirm graphs stabilize near zero and top-app rankings flatten.
  • Time-window sensitivity: switch between Last 15 minutes and Last 30 minutes and confirm views rescale instantly.
  • Auto-refresh control: toggle auto-refresh off and on; verify updates resume without reloading the page.

Acceptance criteria

  • Analytics → Dashboards (global) reflects live activity for the z40 within short time windows, with auto-refresh working as set.
  • Top Apps/Domains clearly surfaces the active application(s) as you change traffic.
  • Overview → Edge Controller – bandwidth and Client/LAN PC bandwidth respond to traffic start/stop and align with the device view.
  • Edge Controllers → [z40] → Analytics → Statistics → Interfaces shows live rate/counter movement that matches the global views.
  • Edge Controllers → [z40] → Analytics → Statistics → Logs and Events records transient link/tunnel changes during the same live window, consistent with observed traffic.

Notes & tips

  • Use a single, easy-to-spot app (e.g., Teams) first; then introduce a second pattern (file download) to show ranking shifts.
  • Short windows (Last 15 minutes) make live changes obvious.
  • If ACI or app-aware routing is enabled in your earlier networking tests, you can show how the live app mix influences which interface carries traffic, then validate it here in real time.
