description: "Understanding why Tracer uses eBPF for observability"

Traditional approaches rely on logs, metrics exporters, or code instrumentation.<br/>
With eBPF, Tracer:

**See everything**<br/>System calls, process lifecycle, I/O, and scheduling events

**Stay lightweight**<br/>Sampling at kernel level without copying large data

**Stay safe**<br/>Verified, sandboxed bytecode that cannot crash your node

**Stay universal**<br/>Works with any container, binary, or programming language

The result: zero-overhead visibility into black-box tools, a critical advantage for bioinformatics and computational biology pipelines.
