Asserts records amends such as new versions, config updates, 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, a metric like
redis_instance_infohas a label
redis_versionand the label_value is tracked by Asserts 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", "(.+)"))
