## ⚠️ Discontinuation of the project

The **vltrace** project will no longer be maintained by Intel.

- Intel has ceased development and contributions including, but not limited to, maintenance, bug fixes, new releases,

or updates, to this project.

- Intel no longer accepts patches to this project.

- If you have an ongoing need to use this project, are interested in independently developing it, or would like to

## Introduction

This is the top-level README.md of vltrace.

vltrace is a syscall tracing tool which utilizes eBPF - an efficient tracing feature of the Linux kernel.

## LICENSE

Please see the file [LICENSE](https://github.com/pmem/vltrace/blob/master/LICENSE)

for information on how this tool is licensed.

## DEPENDENCIES

The vltrace depends on [libbcc](https://github.com/iovisor/bcc) library.

The installation guide of libbcc can be found [here](https://github.com/iovisor/bcc/blob/master/INSTALL.md).

## SYSTEM REQUIREMENTS

 - kernel v4.7 or later [(to attach eBPF to tracepoints)](https://github.com/iovisor/bcc/blob/master/docs/kernel-versions.md)

 - kernel headers installed:

    - 'kernel-devel' package on RHEL, Fedora and CentOS or

    - 'linux-headers' package on Debian and Ubuntu

 - libbcc v0.4.0

 - CAP_SYS_ADMIN capability (required by the bpf() syscall)

 - mounted debugfs and tracefs
