Endpoint Signalling traces

The Signalling Traces tab provides access to control-plane network signalling data for troubleshooting and analysis.

Note: Signalling Traces require a feature flag to be enabled for your account.
Availability and depth of signalling data may depend on your account type.

Accessing Signalling Traces

To view signalling traces for an endpoint:

1. Navigate to Inventory → Endpoints
2. Select an endpoint
3. Open the Signalling Traces tab

---

What Are Signalling Traces?

Signalling traces show the underlying network activity associated with an endpoint’s connectivity.

They represent the control-plane interactions that occur when an endpoint:

• Connects to the network
• Authenticates with the network
• Creates or ends a data session
• Changes network state

These traces provide detailed insight into how the network is handling the endpoint.

Filtering

You can filter traces using:

• Protocol — Select which protocols to include (e.g. SS7, DIAMETER, GTP)
• From / Until (UTC) — Define the time range

Click Search to load results.

PCAP Export

The PCAP option allows you to download signalling trace data for offline analysis.

What is a PCAP File?

A PCAP file contains captured network data.

In this context, it contains signalling data for the selected filters and time range.

Exporting a PCAP File

To export signalling data:

1. Apply the required filters
2. Click PCAP
3. Download the generated file

---

Viewing a PCAP File

PCAP files can be opened using tools such as:

• Wireshark

To view:

1. Open Wireshark
2. Load the downloaded file
3. Inspect the signalling data

When to Use Signalling Traces

Use this view when:

• An endpoint is not connecting to the network
• A data session is not being created
• The endpoint is attaching but not behaving as expected
• Events do not provide enough detail

For traffic-level issues, use the Packet Capture tab.
