Creating Custom Metrics

Extend DbtMetric to create custom dbt-based metrics:

from checkup_dbt import DbtMetric

class MyCustomDbtMetric(DbtMetric):
    name = "my_custom_metric"
    description = "My custom dbt metric"

    def calculate(self, context, measurements):
        manifest = self.get_manifest(context)
        return self.measure(value=len(manifest.nodes))
