Connection issues

Check connectivity

Perform the following steps to verify active connections to the data source and egress endpoints.

• PI Web API: Log into PI Web API and verify that the PI point values are updating.

• CONNECT data services: Log into CONNECT data services and verify that the stream values are updating.

If configured, use a health endpoint to determine the status of the adapter.

For more information, see Health and Diagnostics.

Adapter connection to egress endpoint

Certain egress health information in both PI Web API and CONNECT data services display if an adapter connection to an egress endpoint exists.

To verify an active connection, perform one of the following procedures:

PI Web API

To determine if a connection to the PI Web API endpoint exists:

1. Open PI Web API.

2. Select the OmfEgress component of your adapter (e.g., GVAdapterUbuntu.DNP3.OmfEgress).

3. Verify the following PI points have been created for your egress endpoint:

   • DeviceStatus

   • NextHealthMessageExpected

   • IORate

CONNECT data services

To determine if a connection to the CONNECT data services endpoint exists:

4. Open CONNECT data services.

5. Select Sequential Data Store > Streams.

6. Verify the following streams have been created for your egress endpoint:

   • DeviceStatus

   • NextHealthMessageExpected

   • IORate

TCP connection

Perform the following steps to see all established TCP sessions in Linux:

7. Open a terminal.

8. Type the following command:

   ss -o state established -t -p

9. Select Enter.
