Pitometer is an open-source Node.js project designed to automate deployment validation in continuous integration and continuous deployment (CI/CD) workflows by providing a metrics-based scoring system. Originating from discussions at Neotys PAC 2019, Pitometer allows teams to define indicators, such as monitoring, testing, security, or code quality metrics, from various data sources to assess the quality of software deployments. These indicators are graded against predefined thresholds, baselines, or past results to calculate an overall deployment score, determining if a deployment passes. Pitometer can be integrated with keptn, a control plane for continuous deployment and operations for cloud-native applications on Kubernetes, or used standalone in existing delivery pipelines. The project aims to streamline deployment validation, reducing the extensive manual time traditionally spent by quality engineers, and is extensible for additional data sources and grading algorithms. It has garnered contributions from companies like Dynatrace, Neotys, and T-Systems, and encourages broader participation from the tech community to enhance its capabilities.
