OpenTelemetry is an open-source CNCF project that provides vendor-neutral, standardized APIs, SDKs, and agents for collecting and exporting observability data such as metrics, logs, and traces. Option C is correct because OpenTelemetry’s purpose is to unify how telemetry data is generated, transmitted, and consumed, regardless of which backend (e.g., Prometheus, Jaeger, Elastic, commercial APM tools) is used.
Option A is incorrect because OpenTelemetry supports all three signal types (metrics, logs, traces), not just logs. Option B is incorrect because it is an open, community-driven standard and not tied to a single vendor or cloud provider. Option D is misleading because OpenTelemetry covers distributed applications, services, and infrastructure—far beyond just infrastructure monitoring.
OpenTelemetry reduces vendor lock-in and promotes interoperability, making it a cornerstone of cloud native observability strategies. Platform engineering teams rely on it to ensure consistent data collection, enabling better insights, faster debugging, and improved reliability of cloud native platforms.
