A customer had a vehicle go offline multiple times in a specific time period.
I'm trying to find when those events happened in the past, because once the device is back online, it updates everything to smooth over those offline periods.
Is there a measurement/engine fault that records that?
Is there a specific line item in the log data?
Thanks for the help.

Other than that, I believe disconnections are registered as Faults that you can query. My guess is that they'd have a Diagnostic with a DiagnosticType of either GoFault or GoDiagnostic. I don't have direct experience with these, though, so take that with a grain of salt.
Hello @CarmineTWEX-1098
By off-line you mean out of coverage or truly off-line like it is unplugged?
@sjohnson-6023 I'm referring to out of coverage and unplugged.
The key with out of coverage is that once the vehicle is in coverage, that designation is wiped away and there's no history.
@CarmineTWEX-1098 the device if its on but out of coverage will store and forward. Unless we are talking OEM. Unplugged the only thing you can find is the odometer jump accounting for the mileage while it was unplugged.
The offline report or Watch dog as said below is a good tool. Also in the Engine Data you can look for unplug/replug events.

To figure out when a device was offline, you can check the following logs in MyGeotab:
1. Log and collision data: Go to Activity > Log and collision data.
2. Radio access technology: Look for the 'Radio access technology' diagnostic. Changes in these logs or long periods without GPS/engine updates while the vehicle is in use indicate disconnections.
3. Engine faults: Look for faults like 'Backfill pending' or 'Telematics device fault,' which can be recorded when the device loses communication.
