Troubleshooting

Sensor Homepage and HTTP Server

The sensor HTTP server page http://os-991900123456.local/ has information about the sensor system information, sensor status, firmware, diagnostics, configuration and API documentation. To learn more about Web UI and its use to troubleshoot the sensor, please see the Sensor Web Interface portion of this user manual.

Networking

Many initial problems with the sensor are associated with it not properly being assigned an IP address by a network switch or DHCP server on a client computer. Check your networking settings, the steps in What’s in the box, and that all wires are firmly connected if you suspect this problem. Note that if the sensor is not connected via gigabit Ethernet, it will stop sending data and will output an error code if it fails to achieve a 1000 Mb/s+ full duplex link. Please see the Networking Guide for detailed guidance on network setup.

Using Latest Firmware

Upgrading to the latest firmware can often resolve issues found in earlier firmware. The latest firmware is always found at Ouster Downloads. Our Support team is best suited to be able to help you if you are running the latest firmware. Please refer to the Updating Firmware section to learn more on how to update firmware.

Note

Please contact our Field Application Team and we can answer your questions and provide guidance for achieving proper operations.

Alerts and Errors

The sensor provides alerts and error messages that can be used to help diagnose the sensor. These Alerts are accessible through the diagnostics tab on the sensor homepage. Alternately, users can query the sensor via the HTTP endpoint GET /api/v1/sensor/alerts.

An alert gets triggered when its trigger condition is met and is cleared when the respective trigger condition no longer exists.

GET /api/v1/sensor/alerts returns two lists, an active list and a log list. The active list will contain alert-trigger events for alerts that are currently active. An alert-trigger event will by definition always have its active attribute set to true. There is no limit on the number of alert-trigger events that are displayed in the active event list. All currently active alert-trigger events will be displayed in the active event list.

The log list will contain all current and past alert-trigger and alert-clear events. An alert-clear event will by definition have the exact same attributes and attribute values as its corresponding trigger event, with the exception of the realtime and cursor attributes which should have higher values, since an alert-clear event will always be received after an alert-trigger event. The log list has a length limit of 32 events with the oldest events automatically removed from the log list once a new event needs to be added to the log list and the log list length limit is reached, essentially acting as a FIFO (First In First Out) queue.

In addition to the active and log lists, GET /api/v1/sensor/alerts also returns a next_cursor field. Every alert event has a cursor attribute, which increments for every alert event logged. This can be used to track the alert activity that has been viewed and reduce message bandwidth. To do this, users are recommended to save the next_cursor field when calling GET /api/v1/sensor/alerts and then use that value as the START_CURSOR argument on the next GET /api/v1/sensor/alerts call to fetch only new log entries.

A valid value for mode is either summary or default.

Additional Information:

The cursor will wrap at 2^32 entries. It is important to understand the behavior during the wrap case, since this may lead to some unexpected consequences:

  • If cursor < (next_cursor - 32) % 2^32 then some entries may be filtered. For instance if cursor =0 and next_cursor =0 no entries will be reported immediately after cursor wrap, even though the log contains 32 entries, where submitting cursor =4294967264 (next_cursor - 32) % 2^32 will return all logged values.

  • If cursor > next_cursor all 32 entries will be reported.

Alerts Example

Valid uses of GET /api/v1/sensor/alerts:

Note

When utilizing HTTP Endpoints, the sequence in which the cursor and mode arguments are provided for the GET /api/v1/sensor/alerts command is inconsequential.

The recommended approach to using the interface is to always base queries on the previous value of next_cursor.

If the watchdog is triggered, an alert code will be appended to the end of the response. The sensor has a limited-size buffer that will record the first few alerts detected by the sensor.

The full list of possible alerts and error messages can be found in Alerts and Errors.

The alerts reported have the following format:

{
   "category": "Category of the alert: e.g. OVERTEMP, UDP_TRANSMISSION",
   "level": "Level of alert: e.g. NOTICE, WARNING, ERROR",
   "realtime": "The timestamp of the alert in nanoseconds",
   "active": "Whether the alert was active or not at the time of this log: <true/false>",
   "msg": "A description of the alert",
   "cursor": "The sequential number of the alert, starting from 0 counting up",
   "id": "The hexadecimal identification code of the alert: e.g. 0x01000017",
   "msg_verbose": "Any additional verbose description that the alert may present"
}

Example showing active and logged forced temperature sensor failures occurring at timestamps 1569712873477772800, 1569712879991844096, 1569712884968876544 (nanoseconds).

The first logged error then resolves itself at 1569713260229536000.
