Description: Customers using the CircleCI OTel integration have access to spans for pipelines, workflows, jobs, tasks, and steps — but CPU and memory utilization data is not currently emitted at the task/executor level. Without this, customers cannot build custom alerting to detect over- or under-provisioned executors, which is a key use case for teams looking to optimize resource usage and control compute costs. Proposed solution: Emit CPU and memory utilization as span attributes at the task/executor level. Suggested attribute names aligned with OTel semantic conventions: process.cpu.utilization system.memory.usage / system.memory.utilization Impact: Enables executor right-sizing without requiring third-party agents or parallel jobs Supports custom alerting on resource anomalies directly from pipeline telemetry Strengthens CircleCI's OTel integration
