OTel telemetry support for Copilot CLI (parity with Claude Code) #2471
Description
Describe the feature or problem you'd like to solve
Telemetry of copilot CLI agent
Proposed solution
Feature Request: OpenTelemetry observability support
Claude Code ships full OTel support (CLAUDE_CODE_ENABLE_TELEMETRY) with:
- Metrics: token.usage, cost.usage, session.count, lines_of_code.count, commit.count, active_time.total
- Events via OTLP logs: user_prompt, tool_result, api_request — all correlated by prompt.id
- Exporters: OTLP (gRPC/HTTP), Prometheus, console
- Enterprise: managed settings, dynamic auth headers, multi-team OTEL_RESOURCE_ATTRIBUTES
Copilot CLI currently only exposes /usage and /context in-session. For teams migrating from Claude Code or running autonomous agent workflows (fleet, delegate, headless), this is a
significant gap.
Example prompts or workflows
The more autonomous the agent, the greater the value it delivers. Letting agents run fully autonomously — whether in the terminal or in the cloud — would be a significant force multiplier: I could still review the full execution history after the fact to diagnose any issues, misconfigurations, or prompt errors, without needing to supervise every step in real time.
