Container with datalog¶
To facilitate debugging of FMUs assemblies, the datalog feature is extremely helpful. 
You can enable datalog in two ways:
- CLI: add the
-datalogoption to thefmucontainercommand. - GUI: in FMU Container Builder, open Configuration and check Enable Datalog before saving.
When enabled, a CSV file is automatically generated. The file name is derived from the FMU container’s name and contains the values of all signals exchanged during the simulation, recorded at each container time step.
