Troubleshoot CONNECT to PI connection issues

Check connectivity and data flow

Perform the following steps to verify active connections to the data endpoints.

1. Verify CONNECT data services is operational.

   1. Log into CONNECT data services.

   2. View the System Health tile. A healthy system will display a green heart icon with a status of Ok.

   3. Select the System Health tile to view detailed information on the health of all CONNECT data services. Healthy services will display a green check mark.

2. Verify the status of the agent.

   1. From the CONNECT data services portal, select Data Collection > PI Agents, then select CONNECT to PI Agents from the agents dropdown selector.

   2. Verify the agent status from the table. A healthy agent will have a Good status. An agent that is not connected to CONNECT data services will have a Lost Communication status. An agent that is missing data endpoint configuration will have a No data endpoints configured status; this can be fixed by running the CONNECT to PI Configuration Utility to recreate configuration files.

3. Verify the transfer is operational and transferring data. From the CONNECT to PI Agents page:

   1. Select an agent.

   2. Select a transfer.

   3. Select Monitor on the transfer dialog.

   4. Verify data flow using the metrics Average Data Rate, Average Error Rate, Total Streaming Events, and Last Update Time.

4. Verify the data streams configured for transfer in the agent have data available for transfer.

   1. From the CONNECT data services portal, select Data Collection > PI Agents, then select CONNECT to PI Agents from the agents dropdown selector.

   2. Select an agent.

   3. Select a transfer.

   4. Select View on the transfer dialog.

   5. Select a stream.

   6. Select View in Trend.

   7. From the trend, verify there is data available.

5. Verify the PI Point values are updating in the PI Server.

   1. Open PI System Management Tools (PI SMT).

   2. Use the Archive Editor to search for the PI Points and verify there is data available.

   3. Refer to PI System Management Tools 2023 for more details.

6. For additional details on agent connectivity and data flow, check the agent's Health and diagnostics information.

Agent health and diagnostics

The agent sends health and diagnostics information about itself, its host computer, and its network connectivity to CONNECT data services. The agent health and diagnostics information is available in the CONNECT data services portal, and reflected in the transfer Metrics window, but it is also available as data streams that can be viewed and analyzed. In addition, each transfer configured on the agent will send health and diagnostics information.
