ktraced

Kernel tracing and language runtime profiling scripts ;D [WIP]

BPF Portability

Since epbf-related tracers may have a problem to be able to run on multiple kernel versions without modification, this repository adopts the CO-RE (Compile Once - Run Everywhere) approach to write some scripts.

Tracers

Main tracers

  • ebpf
  • ftrace (bpf-tools)
  • perf (bpf-tools)

Languages

  • bpftrace
  • BCC [on-hold]

oci-cri

For tracing and profiling scripts aimed to run inside an OCI containers managed by k8s CRI.

co-re

CO-RE approach to BPF scripting.

  • ayaya: ...rust
  • constr: Directory for tracing and profiling scripts aimed to run in constrained environments such as embedded systems or lightweight containers and microVMs. Busybox OS and musl libc expected.

jit

Aimed for jit-compiled environments.

  • hotspot: jvm hotspot scripts
