# Network analytics

Last updated Sep 4, 2026|Copy as Markdown| [View as Markdown](https://cb4c3fd6.previews.developers.cloudflare.com/cloudflare-wan/analytics/network-analytics/index.md)| [Agent setup](https://cb4c3fd6.previews.developers.cloudflare.com/agent-setup/)

You can access real-time and historical network data in Network Analytics. Explore Cloudflare WAN traffic (in packets or bytes) over time in a time series, and filter the data by different [packet ↗](https://www.cloudflare.com/learning/network-layer/what-is-a-packet/) characteristics.

Data is aggregated into time intervals that vary based on the selected zoom level. For example, a daily view shows 24-hour averages, which can flatten short-term traffic spikes. As a result, longer time intervals display lower peak bandwidth values compared to more granular views like five-minute intervals.

For details, refer to the [Network Analytics](https://cb4c3fd6.previews.developers.cloudflare.com/analytics/network-analytics/) documentation.

## Network traffic data filters

With Cloudflare WAN, you have increased insight into traffic flows across Cloudflare One products, including:

- Traffic entering Cloudflare's network via the Cloudflare One Client
- Traffic leaving Cloudflare's network via the Cloudflare One Client
- Traffic leaving Cloudflare's network via Cloudflare Tunnel ( `cloudflared`)

The complete list of filters includes:

- A list of your top tunnels by traffic volume.
- Traffic source and destination by traffic type, on-ramps and off-ramps, IP addresses, and ports.
- Destination IP ranges and ASNs.
- Protocols and packet sizes.
- Samples of all GRE or IPsec tunnel traffic entering or leaving Cloudflare's network.
- Mitigations applied (such as DDoS and Cloudflare Network Firewall) to traffic entering Cloudflare's network.

For instructions, refer to [Access tunnel traffic analytics](#access-tunnel-traffic-analytics).

## Access tunnel traffic analytics

1. Go to the **Network Analytics** page.

[Go to **Network analytics** ↗](https://dash.cloudflare.com/?to=/:account/networking-insights/analytics/network-analytics/transport-analytics)

2. In the **All Traffic** tab, scroll to **Top Insights** to access network traffic filters. By default, the dashboard displays five items, but you can display up to 25 items at once. To change the number of items, select the drop-down menu.
3. (Optional) Hover over a traffic type. You can then filter for that traffic or exclude it from the results.
4. To adjust the scope of information, scroll to **All traffic** > **Add filter**.
5. In the **New filter** popover, select the data type from the left drop-down menu, an operator from the middle drop-down menu, and an action from the right drop-down menu. For example:

   ```txt
   <DESTINATION_TUNNELS> | _equals_ | <NAME_OF_YOUR_TUNNEL>
   ```

   This lets you examine traffic from specific Source tunnels and/or Destination tunnels.

## Feature notes

- For Cloudflare WAN, `Non-Tunnel traffic` refers to traffic outside GRE or IPsec tunnels. This can include traffic from:
  - [Cloudflare One Client](https://cb4c3fd6.previews.developers.cloudflare.com/cloudflare-one/team-and-resources/devices/cloudflare-one-client/)
  - [CNIs](https://cb4c3fd6.previews.developers.cloudflare.com/network-interconnect/)
  - Traffic destined for the public Internet via [Gateway](https://cb4c3fd6.previews.developers.cloudflare.com/cloudflare-one/traffic-policies/)
  - Traffic destined for applications behind [Cloudflare Tunnel](https://cb4c3fd6.previews.developers.cloudflare.com/cloudflare-one/networks/connectors/cloudflare-tunnel/)

The label `Non-Tunnel traffic` is a placeholder, and Cloudflare will apply more specific labels to this category of traffic in the future.
