I explained some metrics that could be used before:
Percentage of which the vehicle was with engine on:
Many people prefer to get the data in percentage instead of time, the only way of doing this is using the duration of the report.
Also, you can try to use such parameter as Utilization in Engine Hours table, which shows the percentage ratio of the duration of engine hours to engine hours rate (engine hours divided by daily engine hours rate indicated in the unit properties in the Advanced tab). You can set the daily engine hours (for example, 24 hours), calculate utilization and then, using the calculator, find the percentage of time when the vehicle was not working. Maybe, this will allow you to solve some tasks.
If you use this metric in a day that is not complete or an interval that isn't filled with whole days, it won't work properly.
The time with ignition off and it's percentage:
The same client asked for this value cause some units works almost 24 hours, so engine off sometimes it's a better metric for them.
Mean time between stops/parkings/maintenances:
Knowing the mean time between an event is very important cause you'll know in average, the time that the events happen. For maintenances, for example, you can use this metric to know which vehicles in your fleet are the most problematic and you can also be prepared for the services.
For the parkings, like I said before, the client will use to control the productivity of the forklifts in a different way: they cannot do many stops and the stops must have a big interval between each one, cause if they don't, the drivers are unnecessarly stopping during the trips.
These are just some metrics that I found usefull, probably with the duration of the report the partners will be able to get more.
