Configuration Guide

In this folder you can find some example configuration files. At the moment, these are:

• idle.json: Only log the sensor measurements without stressing the CPU in any way until CTRL+C is pressed.
• long.json: Stress all cores from 0 to 100% and back, with 10% steps of 30 seconds each. This takes approximately 10m30s.
• short.json: For testing purposes, use the loader module but stress the CPU at the minimum level for 5 seconds, without saving files.

You can create your custom configuration files based on these. For example, to stress all cores to 50% for 10 seconds, and then cores 1 to 35% and 4 to 65% for 20 seconds, use

{
    "instruments": ["sensor", "loader"],
    "analyze": true,
    "loader": [
        {
            "target_cores": "all",
            "target_loads": 50,
            "duration": 10,
            "sampling_interval": 0.1
        },
        {
            "target_cores": [1, 4],
            "target_loads": [35, 65],
            "duration": 20,
            "sampling_interval": 0.1
        }
    ],
    "sensor": {
        "sampling_interval": 0.1,
        "file_name": "auto"
    }
}

Note that cores are numbered from 1, whereas some other programs might count them from 0.

The instruments you select direct the operation of the test. Available instruments are:

• sensor: Measures temperature and other parameters.
• loader: Controls the load on the CPU for a specified time.
• timer: Allows to set a duration for the test if loader is not present.

Typically, sensor and loader should be included.

The key "analyze": true, specifies that you want to visualize the results after the measurement. If you set it to false, you can always analyze the results later using rethebes analyze <output-file>.

In sensor, use "file_name": "auto" to save the measured results to the default folder (~/.rethebes/output/) and name them with the time stamp corresponding to the start of the test. Alternatively, you can specify a file path using this key. If you do not want to write the results to file, use "write": false.

Other keys to configure the instruments should be self-explanatory from the examples.
