Device Profile Counters

Device Profile Counters report long term, low frequency counters for performance monitoring and prediction.
This is commonly used on battery powered devices.

What do the counters tell us?

Counters will allow you to monitor the performance of each device, such as voltage, GPS fix time, upload time, etc. If certain trends are seen, such as an increased Failed GPS Fixes, this allows the user to determine if certain parameters, such as GPS Settings, will need to be modified. 

It can also be used for battery usage trends. For example, a failed upload uses up to 20 times the power of a successful upload. This is because a failed upload scans the bands for 3 minutes (registration timeout), while a successful upload is typically done within 5 – 10 seconds. This can be seen in photo of the counters below. The device had over 18,000 uploads with a successful upload time of slightly over 2 days while the roughly 2,700 failed uploads had the device on, attempting an upload for over 13 days.

Where are the counters found?

Device Counters can be found via:

  1. Device Details in OEM
  2. Device Logs
  3. Battery Management page in Telematics Guru

To view within OEM, click on details for the device you are interested in:

This will open a new window. The device counters can be found at the bottom of the details section.

Historical counter values will appear in the Device Logs

However the format is not as readable as in the Device Details Section:

HTTP Connector Settings

Device counters are sent to third party endpoints but OEM filters them out by default via HTTP connections. To send the device counters through the HTTP connector the below will need to be added to the XML of your connector.
