1. A method of collecting vehicle operation data from a vehicle for later transmission to a remote monitoring recipient in a manner to minimize the bandwidth requirements for the later transmission, comprising the steps of:
- providing a vehicle on-board computing device;
providing a number of data acquisition modules, each to measure one or more operating characteristics of the vehicle, the operating characteristics corresponding to current values of a set of managed objects;
interfacing the vehicle on-board computing device with each of the data acquisition modules;
configuring the vehicle on-board computing device to;
a) form a diagnostic information base for receiving and storing values for each of the managed objects from each of the corresponding data acquisition modules;
b) assemble an event report based on information contained in the diagnostic information base; and
c) package the event report in a protocol data unit according to an SNMP-derived protocol.

19. A method of conveying vehicle operation data from a vehicle to a remote monitoring recipient, comprising the steps of:
-
establishing a data link between the vehicle and the remote monitoring recipient;
collecting vehicle operation data from data sources in the vehicle;
packaging the vehicle operation data in a data packet using protocol derived from SNMP; and
conveying the data packet over the data link, the protocol data unit being issued in response to a request by the remote monitoring recipient and containing both the request and requested values in the request and being encapsulated within a single message and in a single unfragmented network packet.

20. A computer implemented system for conveying vehicle operation data from a vehicle to a remote monitoring recipient, comprising:
-
an vehicle on-board computing device in communication with a number of vehicle operation data sources in the vehicle;
a wireless communications device for establishing a wireless data link with the vehicle on-board computing device and the remote monitoring recipient;
the vehicle on-board computing device being enabled to package the vehicle operation data in a data packet using protocol derived from SNMP for transmission to the remote monitoring recipient over the wireless data link.
