🌟 System observability is critical, but tracking everything happening inside an operating system kernel can introduce a massive performance tax. Traditional telemetry frameworks often degrade system performance because moving huge volumes of event data from kernel space to user space creates high memory overhead and CPU bottlenecks.

📖 To solve this scalability crisis, modern kernel observability subsystems (like eBPF and BPF ring buffers) are abandoning old, fragmented designs. Instead of maintaining isolated event buffers for every individual CPU core, newer architectures leverage highly optimized, shared ring-buffer transport mechanisms.

💡 This architecture sets up shared memory regions that support concurrent event production. Because these regions can be memory-mapped (mmap) directly into user space, user-space tools can read the telemetry data instantly without expensive data-copying operations or constant context switching, drastically increasing throughput.

🚀 By shifting to a unified, high-throughput event streaming architecture, modern systems can capture deep telemetry under heavy workloads without lagging.
