Drill-down Information

From the Units tab, you can drill down to see information about the reports from a single vehicle:
 

1. Select the type of raw data you want to see. You can choose:
 
•Raw Data (details about every point from the vehicle)
•GPS/IGN (a summary of GPS signal quality and readings from the ignition and inputs)
•Log (GPRS) (information from GPRS units about resets and power cycles)
 
2.Select the number of days of data you want to see.
3.Click Go. The detailed information is displayed on the Results tab.

Raw Data

If you drill down for Raw Data information, the Results tab shows the following information for each point (report) from the unit on the selected vehicle:

_point_id

The internal (system) ID for the data point.

unit_id

The internal (system) ID for the unit on the vehicle.

_days, _hours, _mins

The time delay between the GPS unit taking a position reading, and the system receiving the data. (Difference between time and _timerecv). This is of no great concern if under 5 minutes when the ignition is on.

Note: if the vehicle is parked, the unit goes into sleep mode. In this case a point can be very late because units do not always report immediately until the ignition is turned on.

_timerecv

The time that the server received the point (in GMT time).

i1

Input 1 reading: 1 = high (12V), 0 = low (ground).

i2

Input 2 reading: 1 = high (12V), 0 = low (ground).

service

Cellular service flag: 1 = has service; 0 = no service.

gpsquality

The quality of the GPS signal. 3=Good, 2=OK, 1=Poor, 0=no signal.

ign

Ignition state: 1 = on or 12 V, 0 = off.

mph

Speed in miles per hour.

heading

the direction the vehicle is heading in degrees (0 to 360).

time

The timestamp on the GPS reading (in GMT time).

lat

The latitude of the GPS reading.

lon

The longitude of the GPS reading.

address_id

The internal (system) ID of the address.

address

The approximate address of the vehicle at the time of the GPS reading.

GPS/IGN

If you drill down for GPS/IGN information, the Results tab shows the following information for each day in the specified time period:

id

The internal (system) ID of the unit installed on the vehicle.

tag

The name of the vehicle.

date

The date summarized in this row (for this screen it is always the most recent day of information).

last_recv

The date and time of the last report received from the unit.

i1

The number of points where input 1 was on (high).

i2

The number of points where input 2 was on (high).

noservice

The number of no service points. No service points can be caused by vehicle being out of cell coverage, a bad communications antenna, or an issue with the wireless carrier related to the sim or location of operation.

gpsoff

The number of points when the GPS was not signaling.

gpsbad

The number of points when the GPS signal quality was bad.

gpsok

The number of points when the GPS signal was acceptable but not good.

gpsgood

The number of points when the GPS signal was good.

ignon

The number of points when the ignition was on.

total

The total number of points received.

If there is no data for a column on the day summarized, the value is shown as -1. Look at the lastcontact field to double check this. Typical reasons for no data include:
 

•In maintenance
•Uninstalled
•Lost power
•Bad communication antenna causing unit to stop reporting
•Cellular connection issue or hardware issue

Log (GPRS)

If you drill down for Log (GPRS) information, the Results tab shows a log of every time any of the following occurs:

STATS

The unit resets or power cycles. This might happen a couple of times per day.

ANTENNA SHORTED

The GPS antenna is shorted. You might get a false message on this if the unit power cycles. If the unit did not power cycle at the point where the log indicates an antenna short then you should check the vehicle for a shorted or broken GPS antenna.
