With "1,*" you can rescale high values. This is only needed for high values like MB.
You can rescale such values with

| Warning |
|---|
With Checkmk 2.1, announced by Werk #13640, the Web API was deprecated. This release now (Checkmk 2.2) removes the Web API. We recommend migrating all existing scripts that use the Web API to the REST API. |
| Checkmk Version | Web or Rest API |
|---|---|
| 2.0.0p* | Web-API |
| 2.1.0p* | Web-API |
| 2.2.0p* | REST-API |
