Frequently Asked Questions
Q:What is eBPF?
eBPF stands for extended Berkeley Packet Filter, a technology that allows for the execution of custom code in the Linux kernel without changing the kernel source code or loading kernel modules.
Q:How does eBPF enhance observability?
eBPF enhances observability by enabling developers to collect detailed performance metrics and trace system behavior in real-time, providing insights into application performance and system health.
Q:What are the benefits of using eBPF?
The benefits of using eBPF include improved performance monitoring, the ability to run custom programs in response to events, and enhanced security features through better visibility into system operations.
Q:Is eBPF limited to networking applications?
No, while eBPF originated for packet filtering, it has evolved to support a wide range of applications, including performance monitoring, security, and tracing across various subsystems in the Linux kernel.
Q:What programming languages can be used with eBPF?
eBPF programs are typically written in C, but there are also higher-level languages and tools, such as BPFtrace and Go, that can be used to simplify eBPF development.
