Tracing tool

Aspect Pixie SigNoz/OpenObserve
Instrumentation No instrumentation required Requires manual or auto-instrumentation (OpenTelemetry).
Technology Base eBPF (system-level observability) OpenTelemetry (application-level observability).
Traces Captures system-level and network traces automatically. Requires instrumentation for detailed traces.
Metrics System and application metrics from eBPF. Requires OpenTelemetry metrics exporters.
Logs Limited logs (e.g., HTTP payloads). Full log support when integrated with log pipelines.
Setup Complexity Easy setup, deploy agents on nodes. Requires instrumentation configuration.
Data Coverage System-level visibility (requests, containers, network). Fine-grained application-specific insights (business logic, custom spans).
Use Cases Troubleshooting system issues, quick setup. Comprehensive application monitoring with custom instrumentation.
Resource Overhead Low (eBPF is lightweight). Varies (depends on OpenTelemetry SDKs and backend).
