## Execution duration

You can check the execution duration for each step. Hover your mouse over each step to check the amount of time it has taken for all instances of that step to execute. The icon for each step depends on its status (**Completed**, **In Progress**, **Faulted**, and so on). The duration is displayed by average, minimum, maximum, P95, and P99.
