With the BCC frontend, attaching and executing the probe is as simple as these 3 lines in a python script: usdt = USDT(path=) usdt.enable_probe(probe="snapshot", fn_name="snapshot_probe0") bpf = BPF(text=, usdt_contexts=[usdt]) We need the path of the binary or the process id to insert the eBPF program.

BCC is a set of tools to write, load and execute eBPF programs with Python bindings. What is it used for? Another way to explain BPF is that this technology allows us to attach and run small user-supplied programs on a large number of kernels, user applications, and libraries.

bcc (eBPF-based) From bcc. bcc is a toolkit for creating efficient kernel tracing and manipulation programs, and includes several useful tools and examples. It makes use of extended BPF (Berkeley Packet Filters), formally known as eBPF, a new feature that was first added to Linux 3.15. I think i figured out what was wrong in the original link. I patched the source file of bcc-tools (function bcc_usdt_enable_probe and deeper), compiled and installed this custom version with some printfs to trace why it's failing and it turns out that when parsing the probes list, the probe defined in my program was seen as string with additional quotes, something like this: ""probe-main"".

The currency Last I checked, that library did not compile on Linux, however, with the new bcc/BPF support it should be fixable. In order to use USDT probes with bcc, you'll need a Linux kernel that's new and shiny. By Linux 4.4 (which is used by Ubuntu 16.04 LTS), there's enough BPF to do USDT event tracing, latency measurements, and histograms.

BCC - Tools for BPF-based Linux IO analysis, networking, monitoring, and more - iovisor/bcc * Allow argdist to enable USDT probes without a pid The current code would only pass the pid to the USDT class, thereby not allowing USDT probes to be enabled from the binary path only.
