• Update YAML configuration files, environment variables, and deployment manifests according to established architecture standards.
• Execute unit tests and validation suites to verify that telemetry is accurately generated, transformed, and exported to target backends.
• Perform telemetry gap analysis, comparing existing New Relic data against OTel outputs to identify missing traces, metrics, logs, or resource attributes.
• Assist in updating dashboards, monitoring documentation, and troubleshooting guides to reflect the OTel architecture.
• Investigate telemetry collection and export errors, identifying root causes and collaborating with core platform engineers on complex edge cases.
• Maintain clear tracking and reporting of implementation progress, edge cases, and potential migration risks.
