What is a device health report?
A tracking system is only as good as the devices that report. A device health report lists which units reported recently, which went quiet and for how long, and which report but with a problem: no power, a camera offline or no fresh GNSS fix. Tenders often ask for it at a set interval.
Which columns does the export need?
| Column | Header names it finds | Needed? |
|---|---|---|
| Device | IMEI, Device, Unit, Serial | Yes, or a vehicle column |
| Last report | Last report, Last seen, Last update, Last connection | Yes |
| Vehicle | Plate, Vehicle, Registration, Asset | Optional |
| Site | Site, Branch, Depot, Group, Region | Optional |
| Last fix | Last GPS fix, Last position, GPS time | Optional |
| Power | Ext power V, Power, Voltage | Optional |
| Camera | Camera, Camera status, Video, Offline channels | Optional |
Arabic headers such as «آخر اتصال», «الجهاز», «اللوحة» and «الفرع» are read too.
How is the reporting rate worked out?
Worked example
- The sample has 20 devices in Riyadh, Jeddah and Dammam. The latest report in the file is 2026-10-31 08:00.
- Three devices are silent: one for about 3 days, one for 9.9 days and one that never reported. The rate is 17 / 20 = 85%, below a 95% target.
- Two of them are over 7 days or never reported, so they go on the weekly not-transmitting list.
- One device reports at 0.0 V: a power cut. Two cameras are offline. One device reports, but its last fix is 30 hours old.
- Dammam has the lowest rate, 4 / 5 = 80%, so the field checks start there.
Weekly reports in tracking tenders
Some public tracking tenders ask the contractor for a regular list of devices that have not sent data for a week or more, for device IMEI and SIM records, and for an availability target. This report gives the list and the rate in one file. Use the limits, intervals and target written in your own tender.
Example: a published tracking tender of the Jordanian Ministry of Water and Irrigation asks for a monthly list of devices silent for a week or more, a weekly IMEI and SIM report, and service availability of at least 99.9 % for the SIM connection. Source and date checked 2026-11-03.
What to do with a silent device
- Check the platform side first. SIM status, data plan and server settings can silence many devices at once.
- Look at the last record. A power cut or low voltage before the silence points at the wiring.
- Ask about the vehicle. A vehicle in the workshop, sold or parked for weeks is not a device fault.
- Visit with a checklist. Power, ground, fuse, SIM, antenna and the device lamps.
- Record the fix and the date. The next weekly report shows whether it held.
Your file and the limits of the tool
- The file is read in your browser. If you ask for the emailed report, your settings and the text when it is short are sent to our server with the request, so the link can open the same result, and kept for up to 45 days.
- Files over 5 MB or 50,000 rows are cut, and the page says so.
- All times are read on one clock. Time zone marks are ignored, which is right for a single export.
- Cell text that looks like a spreadsheet formula is exported as plain text in the CSV.
- The limits and the target are typical starting values, not a standard. The result is indicative.
