Summary for 2024-11: Delivered observable, business-value features and reliability improvements across three repositories. Key features delivered include: MongoDB exporter enhancements delivering tombstone monitoring across both DELETED and Gelöschter and new group analytics metrics for better insights into group structures and user engagement; exporter performance and retention improvements with tuned caches for aggregations, a longterm: true label for users without accounts, and removal of slow metrics to boost efficiency and reliability; deployment/configuration cleanup to streamline Ansible group_vars, remove unused files, and consolidate settings for simpler deployment. In schulcloud-server, added missing indexes on GroupEntity (type, users, organization) to speed up group queries; aligned development configuration by replacing lti with ctl; standardized migration monitoring by refactoring service monitor selectors to matchLabels and adding a ServiceMonitor for api-migration-systems. In schulcloud-client, updated development terminology from lti to ctl. These changes collectively improve data visibility, query performance, deployment simplicity, and cross-environment consistency, delivering measurable business value through faster insights and more reliable deployments.

October 2024 monthly summary focusing on business value and technical achievements. Four key features were delivered across two repositories, with reliability and observability improvements driving measurable impact.
