I would like to be able to use custom sensors to provide a granular indication of a business service status. For example, mail: Is the server overloaded: CPU high, memory load, available disk, etc.
The system can gather it, but how can I use custom sensors to give red, yellow, green indication as the system becomes more taxed? The examples and knowledge base are close but not specific enough. Need a way to indicate levels per system resource status. One of the indicators above threshold, yellow indicator; more than one above threshold, red indicator.
