I’m wondering if there is a suggested way to get access to journalctl logs that are out in the field.
Our use case is that we have devices in the field that are going down and staying down, which is most likely due to modem issues that are hard to reproduce during testing. I’m looking for some way to be able to do a post-mortem once the device is brought back online.
I will start using persistent logging going forward, but getting value out of that would require retrieving the device from the field and entering local mode. These are not dev images, so local mode isn’t really an option either.
Do you have any suggestions or users who are gaining access to system/host logs (ModemManager/NetworkManager is my interest) for production devices?
Additionally, I’m looking for a foolproof way to reinitialize modems that are in a bad state. I’ve tried using ModemManager’s DBUS interface to reset modems, but it hasn’t worked in all cases.
