For platform owners and developers to truly grok their service behaviors in Kubernetes, they must understand their services in terms of actual request and responses by HTTP path. Unfortunately, a nearly unlimited number of unique potential paths tends to overwhelm time series capture, making it difficult to get a clear picture of service behaviors. In this talk I’ll introduce the concept of the Service Profile, a custom Kubernetes resource used by Linkerd. The service profile lets operators define permitted routes for the service with regular expressions, which allows Prometheus to scrape and aggregate service behaviors in a manageable way. It also allows operators to set detailed service behavior rules such as retries and timeouts that can be easily reproduced and monitored.
