• Assist in updating dashboards, monitoring docs, and runbooks to reflect OTel architecture.
• Investigate telemetry collection/export errors, identify root causes, and collaborate with core platform engineers on edge cases.
• Maintain tracking and reporting of progress, edge cases, and migration risks.
