Amends

Asserts records amends such as new versions, config updates, and scale up and scale down events by observing changes in metric label values and metric values. Amends are annotated as blue bars on Asserts Workbench.

For example, the metric redis_instance_info has a label redis_version, and the label value is tracked by Asserts as a new normalized label version to record new versions.

- record: asserts:version:info
  expr: group by (namespace, job, service, asserts_env, asserts_site, asserts_source, version)
          (label_replace(redis_instance_info, "version", "$1", "redis_version", "(.+)"))
  labels:
    asserts_source: redis
    asserts_version_type: service
