# Endpoint Agent Local Networks View

The **Local Networks** view shows how Endpoint Agents connect through local network infrastructure, including wireless access points, gateways, DNS servers, proxies, and VPN terminators. Use it to determine whether user-impacting degradation begins close to the endpoint.

## Exploring Local Network Data

1. Go to **Endpoint Experience > Views**. The **Local Networks** view opens by default.
2. Select a data type:
   * **Network Access** shows connections to gateways, DNS servers, proxies, and VPN terminators.
   * **Wireless** compares Endpoint Agents and wireless access points.
3. Select **Add Filter** to focus the view on relevant data.
4. Select a metric above the timeline.

   Transmission rate supports throughput analysis, loss and latency show reachability and delay, and signal quality shows wireless degradation.
5. Select an interval on the timeline. The result tabs below it update to show that selection.

Use **Snapshot > Save a snapshot** to preserve the filters, data type, metric, and time selection. Use **Snapshot > View All Snapshots** to open a saved snapshot. For more information, see [Endpoint Agent Test Snapshots](https://docs.thousandeyes.com/product-documentation/tests/sharing-test-data#endpoint-agent-test-snapshots).

## Filtering the Results

Select **Add Filter** to apply global filters to the timeline and the detailed results. The available filter groups depend on the selected data type:

* For **Network Access**, the groups are:
  * **Agents**: Location, connection, network, ASN, agent, platform, tags, machine model, serial number, NIC model, and NIC driver version.
  * **Network**: Gateway, gateway MAC address, proxy address, SSID, BSSID, and DNS server.
  * **VPN**: VPN vendor, VPN gateway address, VPN client address, and VPN client network.
* For **Wireless**, the groups are:
  * **Wireless**: SSID, BSSID, channel, and physical mode.
  * **Agents**: Location, network, agent, platform, and tags.

The metric selector above the timeline is a separate control. For **Network Access**, the available metrics are:

| Metric group   | Metrics                                                |
| -------------- | ------------------------------------------------------ |
| Network Access | **Transmission Rate** and **Signal Quality**           |
| Gateway        | **Loss** and **Latency**                               |
| Proxy          | **Proxy Loss** and **Proxy Latency**                   |
| VPN            | **VPN Loss** and **VPN Latency**                       |
| DNS            | **Loss**, **Latency**, and **Time**                    |
| System         | **CPU Load**, **Memory Load**, and **Free Disk Space** |
| DHCP           | **Time to Offer** and **Failure Count**                |

For **Wireless**, the **Wireless** group includes **Signal Quality**, **Throughput**, **Retransmission Rate**, **Roaming Events**, **Channel Swap Events**, and **RSSI**.

## Using the Timeline

The timeline shows up to 30 days of data, or data from the time collection began if that period is shorter. Use it to correlate local network changes with user-reported problems.

* Select **24h**, **7d**, or **14d** to change the visible time range.
* Select a point to load that interval in the details section.
* Drag across the timeline to focus on a narrower range.
* Move and resize the timeline selector to examine a window from 24 hours to 14 days.
* Use the previous and next interval controls to move between intervals. Select the latest interval control to return to the most recent data.
* Hover over the timeline to compare the selected metric with the number of reporting agents.

Changing the filters, data type, metric, or interval updates the detailed results.

## Investigating Network Access

Select **Network Access**, and then use **Network Topology** and **Table** to compare the same interval.

### Network Topology

The **Network Topology** tab displays how Endpoint Agents connect to gateways, DNS servers, proxies, and VPN terminators.

You can:

* Change node labels and the visible hop range.
* Group Endpoint Agents, wireless networks, and interfaces.
* Search for a node.
* Highlight nodes or links that exceed a selected loss or delay threshold.
* Select a node or link to inspect it.

Look for a gateway, proxy, DNS server, or VPN terminator shared by affected agents. Compare the same component in a nearby healthy interval to identify changes in its metrics or connected agents.

### Table

The **Table** tab provides a row-based comparison for the selected interval. The columns change with the metric selected above the timeline, so the table does not have one fixed set of measurement columns. Common identifying fields include the Endpoint Agent, time, connection, SSID, channel, and physical mode. The table then displays fields from the selected metric group:

| Metric group   | Metric fields                              |
| -------------- | ------------------------------------------ |
| Network Access | Transmission Rate and Signal Quality       |
| Gateway        | Loss and Latency                           |
| Proxy          | Proxy Loss and Proxy Latency               |
| VPN            | VPN Loss and VPN Latency                   |
| DNS            | Loss, Latency, and Time                    |
| System         | CPU Load, Memory Load, and Free Disk Space |
| DHCP           | Time to Offer and Failure Count            |

For example, selecting **Memory Load** displays the connection fields together with CPU load, memory, free disk space, battery status, and battery health.

Search, sort, or select rows to isolate affected agents and local components. Use the table to validate a pattern seen in **Network Topology**.

VPN server probes and their VPN metrics appear only while an Endpoint Agent device is connected to that VPN.

## Investigating Wireless Access

Select **Wireless** to compare Endpoint Agents and access points for the selected interval.
