Export model

An export model decides which output files OpenDC writes, which columns they have, and how often a sample is taken.

Field	Type	Default	Description
exportInterval	integer	300	The time between two samples, in seconds.
printFrequency	integer or null	24	Print a progress line every this many samples. null turns progress lines off.
filesToExport	list of strings	all files	The files to write. Choose from host, task, powerSource, battery and service.
computeExportConfig	compute export config	all columns	The columns to write in each file.

Columns

computeExportConfig has a list of column names per file. A file without a list gets all of its columns.

Field	Always written
hostExportColumns	timestamp, timestamp_absolute, host_name, cluster_name
taskExportColumns	timestamp, timestamp_absolute, task_id, task_name
powerSourceExportColumns	timestamp, timestamp_absolute, source_name, cluster_name
batteryExportColumns	timestamp, timestamp_absolute, battery_name, cluster_name
serviceExportColumns	timestamp, timestamp_absolute

Column names are not case-sensitive. An unknown column name is ignored with an error message, and a list without any valid column name writes all columns.

Example

"exportModels": [
    {
        "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"]
        }
    }
]

This takes a sample every hour, prints progress every week of simulated time, and writes only the host, task and service files, each with a few columns.
