Logging Mission Operations Guide

Log Sinks

Logs go to the following locations:

• Umbilical UART (useful for ground testing only, of course)
• UHF Radio (disabled by default)
• Files in the /logs/<timestamp>.log folder.

Logging to File

Logging to file is less well-tested than most satellite features. By default, to be in a "fail-safe state", logging to file is disabled.

Do not fear enabling it, but understand that you may experience more system restarts than normal, and certain features may be slower/broken with logging-to-file enabled.

Procedure: Enable Logging to File

1. Enable the FILE (2) log sink: CTS1+log_set_sink_enabled_state(2,1)!
2. For each LOG_SYSTEM you want enabled logs, enable file logging: CTS1+log_set_system_file_logging_enabled_state(32,1)!
3. You will see timestamped files appear in the /logs/ folder.

A new log file is started periodically, based on configuration variable LOG_file_rotation_interval_sec.

Behaviour Notes

• Logs are not immediately written to the file, but rather are buffered and then written to the file periodically, based on the LOG_file_flush_interval_sec configuration variable. You won't see a file appear immediately after enabling file logging.
