On the Asset Counters, you can define the Expected End Of Life Cycle for a particular asset with the counter. For example: you have created an asset representing an engine and you expect that this asset will work for 10,000 running hours or kilometers.
In the Percentage Usage, you can see what is the actual usage of the asset - value calculated based on the actual usage and expected end-of-life cycle.
You can modify how Percentage Usage is presented on the card by specifying thresholds for specific counter categories.
To do this you need to set up thresholds, where you define what ranges you would like to take into consideration.
Later you can define the style for specific values on the selected counter category.
