The eBPF Approach to Container Monitoring


eBPF offers a low-overhead approach to observability.

The extended Berkeley Packet Filter (or eBPF) is poised to upend conventional approaches to monitoring Docker and Kubernetes workloads, says Christopher Tozzi.

The Linux feature, introduced in 2015, offers a way to monitor containers without high resource consumption. “eBPF makes it possible to run programs directly in the Linux kernel – as opposed to running them in "userland," where they don't have direct access to kernel resources,” Tozzi explains.

For example, he says, “you could write an eBPF program that intercepts the processes associated with each container and use it to collect monitoring data. You'd end up with a monitoring solution that is much less resource-hungry than traditional sidecar containers.”
