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 and configuration. To learn more about Web UI and it’s use to troubleshoot the sensor, Please see the Web Interface portion of this user manual

Note

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

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 Connecting to Sensor, 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.

Get Alerts

To check for hardware errors, use the get_alerts TCP command.

If the watchdog is triggered, an alert code will be appended to the end of the response of the TCP command get_alerts. 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 in the Appendix.

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 is active or not: <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"
}

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.

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 get_alerts TCP command and the HTTP endpoint GET /api/v1/sensor/alerts.

An alert would get triggered when it’s trigger condition is met and would get cleared when the respective trigger condition no longer exists within a certain level of heuristics, or when a specific alert clearing condition is met.

get_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_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_alerts and then use that value as the START_CURSOR argument on the next get_alerts call to fetch only new log entries.

A valid value for MODE is either summary or default.

Note

Valid uses of get_alerts:

• Example: Calling get_alerts with START_CURSOR=1

  get_alerts 1

• Example: Calling get_alerts with START_CURSOR=2 and MODE=summary

  get_alerts 2 summary

Invalid uses of get_alerts:

• Example: Calling get_alerts with START_CURSOR=summary and MODE=2

  get_alerts summary 2

Note

The order in which the START_CURSOR and MODE arguments are specified for the get_alerts TCP command must be followed when providing both arguments, with START_CURSOR preceding the MODE. The arguments can be specified in any order when calling the equivalent /api/v1/sensor/alerts HTTP endpoint.

Table of All Alerts and Errors

Possible alerts and errors that the sensor can provide are listed below. Where appropriate, the message from the sensor aims to help the user diagnose and fix the issue themselves.

Note

Please note that if the recommended action does not clear the ALERT and the issue persists, Users are encouraged to update to the latest FW version. If that does not mitigate the issue, please collect the diagnostics file from the sensor Web UI and contact Ouster support.
