---Talk---------
Title: No-instrumentation Log Injection in Go with eBPF.

-------Developer Problem:------

Go programs are designed to be performant but we often don’t have the right code-level instrumentation when a performance issue arises in a production go program. It’s hard to predict where issues will arise and we can’t instrument everything as over-aggressive instrumentation leads to maintenance overheads.

------Motivating Developer Experience:-----

Enable tracing/logging of application code to answer the following questions without instrumentation:

Function Argument Tracing: “What are the arguments being passed to Foo(x, y, z)?”

Function Input-Output Tracing: “What are the arguments and return value of calls to Foo(x, y, z)?”

Conditional Function Tracing: “What are the arguments being passed to SetInfo(user, address) when user==alice?”

Function Latency Tracing (Profiling): “What is the latency (call to return) of calls to Login(username)?”

-----Proposed Solution:------

Write and deploy eBPF userspace-probes native in Linux VMs v4.9+ to dynamically inject tracepoint in your go programs with the following constraints: Less than 5% performance overhead

Reliably start, deploy and stop probes without leaks.

Provide apis to sample, filter and access data.

Presentation Goals & Pixie’s Involvement:

Presentation would be about how go developers can independently write and deploy ann open-source eBPF probe without any back-end dependency. Pixie is one of many potential back-ends to allow developers to deploy such probes at scale. Other projects include BCC, inspector-gadget etc. -

-----Speaker Bio:-----
Ishan is the cofounder of Pixie, an SF based stealth auto-telemetry startup backed by Benchmark and Google Ventures. Teams like Disney use Pixie to access no-instrumentation (via eBPF), streaming & un-sampled telemetry to debug application performance issues without moving data out of their clusters. They’re launching on October 1st and are looking to engage with the golang developer community.
