How to Troubleshoot When Tracks or Trips Have No Data
Common Causes
- The selected date or time range contains no valid records for the device
- The device has been offline for a long time or location updates are unstable
- Filters are too strict, so no results remain visible
Troubleshooting Steps
- Expand the time range to the full day and confirm whether any record exists.
- Return to the monitoring page and check the current device status, such as online or offline, and whether location updates were recently received.
- If historical tracks have no data, check alerts or other dates to determine whether the issue is limited to one day or persistent.
- If multiple devices all show no data, there may be a network or service issue. Try again later or contact the administrator.
FAQ
Q: Why is the track page blank without any error?
A: In most cases, this is the normal empty state for "no records in the selected time range." Adjust the time range or choose another date first.
