Application Log
The Application Log records timestamped severity/category diagnostics for startup, workspace operations, generators and connections. It is separate from opt-in NMEA Traffic Recording. Open the Log Viewer from Tools; use Setup's logging preferences to control verbosity and retention.
Investigate an operation
- Open Log Viewer and select Application.
- Repeat the problem using example values where possible.
- Read matching timestamps, severity, category and message. Use the readable display or raw structured records as appropriate.
- Pause Display while examining a stable view, or click Refresh explicitly.
- Copy/export only the useful reviewed excerpt; redact private paths, identifiers and navigation data before sharing.
Choose useful verbosity
Optional Show Widget Signal Connections/Disconnections is off by default. Enable it temporarily when troubleshooting generator bindings: it records source/destination identities, instances and connection changes. It does not log every changing generator value.
Logs use the per-user application-data logs directory, with application.jsonl and separate traffic.jsonl. The viewer exposes the relevant location and health. Defaults are 2 MiB per Application file and 8 MiB per Traffic file, with four archives plus the current file per channel. Configurable per-file limits are bounded; queues are bounded and health/drop reporting matters.
Pause, Refresh and Clear
| Control | Effect |
|---|---|
| Pause Display | Suspends automatic display refresh; logging/recording continues independently |
| Refresh | Explicitly reloads the selected current file even while paused |
| Clear → Yes | Clears selected current file and immediately updates its view; Pause remains selected |
| Clear → No | Leaves file and display unchanged |
Clear does not delete archives or the other channel. New records may appear again immediately if recording continues. The viewer reads a bounded tail, not unlimited history into memory. A write/rotation failure is a logging-health problem to resolve, not proof that the attempted operation succeeded.
