Noisy Neighbor Detection with eBPF
I recently co-authored a post on the Netflix Tech Blog where we detailed how we’re continuously monitoring the Linux scheduler using eBPF to enhance system observability. By instrumenting the scheduler, we gain real-time insights into CPU resource contention and noisy neighbor issues, all with minimal overhead. This method allows for deeper visibility into Linux performance, improving stability across our multi-tenant infrastructure. For more on how we implemented this, check out the full post here!
