Pro Talk: Tackling Path Parameters w/ Service Profiles and Prometheus
To truly understand service behavior in Kubernetes, you must also understand their requests and responses, including the HTTP path. With a nearly unlimited number of unique potential paths, time series capture tends to be overwhelmed, making it difficult to get a clear picture of service behaviors. In his KubeCon 2019 talk, Alex Leong introduces the Service Profile concept, a custom Kubernetes resource used by Linkerd. It allows operators to define permitted routes for the service with regular expressions allowing Prometheus to scrape and aggregate service behaviors.
