Create a PI Vision network export
If a PI Vision display fails or loads slowly, support may ask for a network export. This HAR file records the browser requests made while the issue occurs.
Use Google Chrome or Microsoft Edge on Windows.
1. Open the Network panel
Open the affected PI Vision display. Press Ctrl + Shift + I to open Developer Tools, then select the Network tab.
2. Prepare the recording
- Check that the recording button at the top left is red. If it is grey, click it to start recording.
- Enable Preserve log to keep requests when the page reloads.
- Select All and empty the Filter box so requests are not hidden.
- Click Clear network log to remove earlier requests.
3. Reproduce the issue
Keep Developer Tools open and repeat the action that causes the problem. If it happens when the display loads, reload the page.
Wait for the issue to appear. New rows should appear in the Network panel; if the list stays empty, check that recording is on and try again.
4. Save the HAR file
Click the Export HAR download button in the Network toolbar. Choose the sanitized option if a menu appears, then save the file with a .har extension.
Check that the file was saved and is not empty.
5. Send the file to support
Attach the HAR file to your support request. Include the display URL or name, what you clicked, what you expected, what happened instead, and the capture time with its time zone.
Before sharing: even a sanitized HAR can contain internal URLs and business data. Review it under your organization's policy and use its approved support channel.
