I am using GeoEvent Server 10.6.1 with the Geotab Connector. I see in the ArcGIS GeoEvent Manager Log an error message that says:
LOGGER
com.esri.geoevent.adapter.geotab.GeotabAdapter
MESSAGE
Failed to set Geotab-DeviceStatusInfo field DriverId to value IdType [id=b2F, children=null, color=null]
Any idea what this means?
I'm experiencing the exact same thing with my Geotab input on version 11.0. Started for me less than a week ago though. No idea what's going on.
It does not seem to be affecting performance for my service. Likely just one of those mysterious, no service impact, log messages that are common in ArcGIS for Server.
Try calling ESRI Tech Support, their Geotab Connector/GeoEvent Server Support is right out of Redlands and very prompt.
