@ -25,5 +25,17 @@ all files in the Kubernetes code base to:
Due to the dynamic nature of how metrics can be written, we only support the subset of metrics
which can actually be parsed. If a metric cannot be parsed, it must be delegated to the stability
class `Internal`, which will exempt the metric from static analysis.
The entrypoint to this package is defined in a shell script (i.e. stability-utils.sh) which has
the logic for feeding file names as arguments into the program. The logic of this program is as
follows:
- parse all files fed in, keeping track of:
- the function and struct pointers which correspond to prometheus metric definitions.
- consts/variable we encounter, so that we can use these to resolve values in metric definitions
- then, iterate over the function and struct pointers, resolving attributes to concrete metric values
- then, using our collected and resolved metric definitions, output (depending on the mode):
- a yaml file corresponding to all stable metrics
- a documentation file corresponding to all parseable metrics in the Kubernetes codebase
