+During simulation, OpenDC exports data to files (see [Output](/docs/documentation/Output.md)).
+The user can define what and how data is exported using the `exportModels` parameter in the experiment file.

+
+
+
+### 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.

+### Example
+
+```json
+{
+    "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.
