ExportModel

During simulation, OpenDC exports data to files (see Output). The user can define what and how data is exported using the exportModels parameter in the experiment file.

ExportModel

Variable	Type	Required?	Default	Description
exportInterval	Int64	no	300	The duration between two exports in seconds
filesToExport	Int64	no	24	How often OpenDC prints an update during simulation.
computeExportConfig	ComputeExportConfig	no	Default	The features that should be exported during the simulation
filesToExport	List[string]	no	all files	List of the files that should be exported during simulation. The elements should be picked from the set ("host", "task", "powerSource", "battery", "service")

ComputeExportConfig

The ComputeExportConfig defines which features should be exported during the simulation. Several features will always be exported, regardless of the configuration. When not provided, all features are exported.

Variable	Type	Required?	Base	Default	Description
hostExportColumns	List[String]	no	name cluster_name timestamp timestamp_absolute	All features	The features that should be exported to the host output file.
taskExportColumns	List[String]	no	task_id task_name timestamp timestamp_absolute	All features	The features that should be exported to the task output file.
powerSourceExportColumns	List[String]	no	name cluster_name timestamp timestamp_absolute	All features	The features that should be exported to the power source output file.
batteryExportColumns	List[String]	no	name cluster_name timestamp timestamp_absolute	All features	The features that should be exported to the battery output file.
serviceExportColumns	List[String]	no	timestamp timestamp_absolute	All features	The features that should be exported to the service output file.

Example

{
    "exportInterval": 3600,
    "printFrequency": 168,
    "filesToExport": ["host", "task", "service"],
    "computeExportConfig": {
        "hostExportColumns": ["power_draw", "energy_usage", "cpu_usage", "cpu_utilization"],
        "taskExportColumns": ["submission_time", "schedule_time", "finish_time", "task_state"],
        "serviceExportColumns": ["tasks_total", "tasks_pending", "tasks_active", "tasks_completed", "tasks_terminated", "hosts_up"]
    }
}

In this example:

• the simulation will export data every hour (3600 seconds).
• The simulation will print an update every 168 seconds.
• Only the host, task and service files will be exported.
• Only a selection of features are exported for each file.
