Troubleshooting

Systems work but no logs recorded

System works as expected which (most probably) means output on IPIO are changing based on events as expected but there's no log of event in records section of Visor, no emails arrive if this was expected.

Diagnostics:

1. There are logs but no videos: encoder exception
2. There are no logs at all: broken SSD - do not restart!
3. There are only older logs: full SSD - do not restart!
4. There are system logs but no event logs and system's new: interpreter
5. There are system logs and old event logs but no new event logs: Vislet issue

Possible cause 1: Vislet exception

An unhandled exception in the pipeline may break recording. Visor must show previous recordings. H/B may not stop.

Possible cause 2: Broken or full SSD

A permanent or temporary problem with the SSD such as high working temperature may break it, permanently or temporarily. In case of an SSD exception do not restart!

In case of full SSD, SSH may fail, restart the system and retry.

Diagnostics

1. Check free space: SSH access yields an exception telling there's no disk space. If there's no free space, housekeeping may not have worked correctly.
2. Check SSD temperature. Consider changing SSD or improve cooling. A broken SSD may prevent from remote access to the device.

Possible cause 3: Encoder exception

This applies only to systems with Jetson modules. Visor and outputs works fine. Emails may fail. Logs are recorded but no video play. System logs show GStreamer/NVidia libraries exceptions. Videos in Visor log page seem to exist but when you try to watch it doesn't load but a indicator keeps turning.

Resolution:

Possible cause 4: Interpreter exception

An interpreter issue may prevent logs from being recorded. This most probably occurs in systems during deployment and should be found out during initial testing. System must be new, or recently altered and had no prior records of logs and/or video. This applies to event logs only. System logs must be there.

Resolution: open a ticket or escalate.
