Configure Splunk Edge Hub Software to connect to an OPC server

To collect metrics from hardware that uses the OPC Unified Architecture (OPC-UA) protocol, configure Splunk Edge Hub to connect to the OPC servers that you want to get data from.

OPC server data uses the edge_hub_logs index and splunk_edge_hub_opcua sourcetype.

Prerequisites and requirements

Complete the following requirements and prerequisites before configuring Splunk Edge Hub Software to support OPC-UA.

Requirements

Your organization is using hardware that supports the OPC-UA protocol and you're using Splunk Edge Hub for AR version or 4.1.3 or higher.

Prerequisites

Register your Splunk Edge Hub and launch the Edge Hub Advance Settings.

1. Register your Splunk Edge Hub. See Register or unregister your Splunk Edge Hub.
2. Create an index for OPC-UA data. See Create indexes for Splunk Edge Hub Software.
3. Complete the steps at Access the Edge Hub Advance Settings.

Steps

In the Edge Hub Advance Settings, compete the following steps:

1. Navigate to the OPC-UA tab.
2. Enter the OPC server name that you want to collect data from.
3. Enter the server URL.
4. Configure the connection details. Select Anonymous or Username and password.
   Anonymous doesn't require authentication. Username and password prompts you to enter your OPC-UA server credentials.
   
5. Select Next. The Edge Hub Advance Settings verifies the OPC-UA connection.
6. Select the metric sources you want to collect data from. You can browse or search for a metric source. The Splunk Edge Hub Software sends data from selected tags that have a Value attribute.
7. Select Next.
8. Configure the sampling frequency. You can choose the publishing interval for data updates. Splunk Splunk Edge Hub Software gathers data using a Data Change Subscription on the OPC server.
9. Select Next to complete the configuration.
