Endpoint Agent Dynamic Tests View

Dynamic tests measure network performance while Endpoint Agents use supported collaboration applications such as Webex, Microsoft Teams, and Zoom. When a user joins a meeting, the Endpoint Agent detects the application activity and starts agent-to-server measurements to the destination used for that meeting. This approach provides destination-specific data without requiring scheduled tests for every possible application target. Use the Dynamic Tests view to identify affected agents and destinations, compare measurements, and locate degradation along the network path.

Exploring Dynamic Test Data

1. Go to Endpoint Experience > Views.

2. Select Dynamic Tests from the set of tabs at the top of the view.

3. Select a test from the Test dropdown.

   The list includes enabled and disabled tests. Search by test name, or select the test settings icon to open the test configuration in a new tab.

4. Select Add Filter to focus the view on relevant data.

5. Select a metric above the timeline. Dynamic tests contain a single Network data type, which is selected automatically.

   Loss identifies failed or degraded paths. Latency and jitter distinguish delay or instability from packet loss.

6. Select an interval on the timeline. The Path Visualization, Map, and Table tabs update to show that selection.

Use Snapshot > Save a snapshot to preserve the current test, filters, metric, and time selection. Use Snapshot > View All Snapshots to open a saved snapshot. For more information, see Endpoint Agent Test Snapshots.

Filtering the Results

Select Add Filter to apply global filters to the timeline and the detailed results. Available filters depend on the selected test. The menu can include:

Filter category	Examples	Use it to
Agents	Location, connection, network, ASN, agent, platform, tags, machine model, serial number, NIC model, NIC driver version, and Metrics	Determine whether degradation is limited to a device, network, or location.
Network	Gateway, gateway MAC address, and other network fields	Correlate application degradation with local access infrastructure.
VPN	VPN vendor and other VPN fields	Compare paths on and off a VPN, or isolate a VPN gateway.
Destination	IP address and meeting app	Separate application destinations measured by the same dynamic test.

Under Agents, select Metrics to filter agents by available network metric conditions. The metric selector above the timeline is a separate control that determines which metric the timeline and detailed results display:

Metric group	Metrics
Network	Loss, Latency, Jitter, and TCP Connect Failures
System	CPU Load and Memory Load
VPN	VPN Loss and VPN Latency

Using the Timeline

The timeline shows up to 30 days of data, or data from the time the test was enabled if that period is shorter. Use it to determine whether a problem affects one application interval or persists across multiple sessions.

• 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 volume of reported measurements.

A dynamic test can measure multiple destination IP addresses for one agent in the same interval. The timeline therefore reports the number of measurements rather than treating every result as a separate agent.

Changing the test, filters, metric, or interval updates the detailed results.

Comparing Detailed Results

Path Visualization

The Path Visualization tab displays the layer 3 path from each Endpoint Agent to the application destination, hop by hop. Use it to identify a shared private or public network segment associated with loss, latency, or forwarding problems.

You can:

• Show or hide the VPN overlay.

• Change node labels and the visible hop range.

• Group agents by network, ASN, private network, location, country, or individual agent.

• Group interfaces by IP address, network, network and location, location, or ASN.

• Highlight nodes or links that exceed a selected threshold.

• Search for and select a node or link to inspect it.

For general interpretation guidance, see Path Visualization.

Map

The Map tab combines metrics for the selected interval with Endpoint Agent locations. Zoom or pan the map to compare regions. Hover over a location to view the agents and basic metrics at that location.

Use the interval controls above the results to compare adjacent intervals or return to the latest data.

Table

The Table tab provides one row per agent and destination measurement for the selected interval. Its columns change with the metric selected above the timeline. Network metrics display the agent, date, destination IP address, connection, SSID, channel, physical mode, packet loss, latency, jitter, error details, and test protocol. For example, selecting Memory Load displays the agent and connection fields together with CPU and memory measurements.

Search, sort, or select rows to compare measurements. Select Apply Filter to focus the view on selected rows, or View Path to inspect their paths. Because one dynamic test can target multiple IP addresses, use Group By to switch between:

• Agent: Aggregate the destinations measured by each agent.

• Agent and Destination IP: Keep each agent and destination combination separate.

Understanding Dynamic Test Path Traces

When a dynamic test uses the Auto-detect protocol setting, the Endpoint Agent selects a suitable probe method for the current network conditions. It uses UDP when applicable and another supported protocol when UDP is unsuitable. The path visualization identifies the protocol used for the collected trace.

Dynamic tests can trace a path by increasing or decreasing the TTL:

Trace method	How it operates	Supported protocols
Increasing TTL	Establishes a connection for connected probes, sends probes with progressively higher time-to-live (TTL) values at 0.2-second intervals or when a reply arrives, records replies, and closes the connection.	ICMP, TCP_SYN, TCP_DATA_IN_SESSION, and UDP
Decreasing TTL	Establishes a connection for connected probes, estimates the remote TTL, sends probes with progressively lower TTL values at 0.2-second intervals or when a reply arrives, records replies, and closes the connection.	ICMP, TCP_SYN, TCP_DATA_IN_SESSION, and UDP

For UDP dynamic tests, the Endpoint Agent sends probes from an ephemeral port assigned by the operating system to the configured target address and port.

UDP mode	Probe content
STUN	A STUN request message
RTCP	An RTCP receiver report packet

For test configuration details, see Configuration Options for Synthetic Tests.

Relating the Data Areas

Each area provides a different perspective on the selected test, metric, filters, and interval:

• The timeline shows when the selected metric changes and how many measurements contribute to each interval.

• Path Visualization shows whether affected agents and destinations share a node or link.

• Table identifies the agent and destination combinations in the interval and the protocol used for each trace.

• Map shows whether the reported measurements are concentrated in a geographic area.
