beyla

eBPF-based autoinstrumentation of web applications and network metrics

Could not verifysource: GitHubhomepageGoApache-2.0commit d6e1d67280ea

Go, Apache-2.0 licensed. The project labels itself: ebpf, metrics gathering, observability and traces.

Argusic could not get beyla running. An Argusic agent installed it in 42 minutes and hit 5 errors and fixed every one without help on a clean machine with no GPU, and the whole session was recorded.

Prebuilt Beyla v3.36.0 binary launches and prints version. 11 Go test packages pass. Example HTTP service compiles. Source build fails due to missing eBPF bytecode generation requiring Docker or clang >=19.

What the agent ended up with on a clean machine, in its own words. How this is measured

Measured by Argusic on a fresh machine every time. Every number links to its evidence. Argusic Score 20 of 100 (the mean of this project's run scores).

What was measured

From the run that decided this verdict. Every line is a recorded value, not an estimate.

Time lost to each failure while testing beyla, drawn from the recorded run
Every bar is a failure the agent recorded, with the time it cost. Drawn from this run, not from anywhere else.

What went wrong, in the agent's own words

The agent's own words, worst first, never rewritten into advice.

What was not measured

The other half, so you can see exactly how far this evidence goes. A gap is printed as a gap and never filled in.

Peak GPU memory
this ran on a CPU machine, so there was no GPU to sample
Behaviour over a long run
each attempt uses the smallest documented settings and a fixed time budget, so this measures whether it runs, not how it holds up under load
Behaviour against real services
this run was verified against stand-in services only

Replay the whole session, every command from a clean machine to this point.

How it was tested

One agent, one container, no human help. It installs the project the way its own documentation says to, runs it, and fixes what breaks. Everything below is recorded as it happened: the terminal session, the log and the exact commit. The full method.

Strengths and limits

Measured facts, not opinions. How this is written.

What went well

  • Installed in 42 minutes.
  • Recovered from all 5 errors without a human stepping in, which says the failures are documented well enough to solve.
  • Licensed Apache-2.0, as reported by its host.
  • Measured 2 times, so the result is not a one-off.

What did not, or is not known

  • An agent with no time limit did not get it running.

Also tested, in the same area

Every one of these was installed and run by Argusic on a clean machine. Nothing appears here that was not tested.

Questions

Does beyla run?
Argusic could not verify that beyla runs. Argusic installed and launched it on a clean machine in 42 minutes, hitting 5 errors on the way, and recorded the session.
How did Argusic test beyla?
On a fresh, disposable machine, with every command recorded and the repository pinned at commit d6e1d67280ea. 2 attempts are recorded, and the full method is on the methodology page.
What did it cost to test beyla?
The run that produced this verdict cost $0.14: real compute and model cost, not a list price per million tokens. It is recorded on that run's page.
How long does beyla take to install?
42 minutes in the run that decided this verdict, from a clean machine to a running state. That is one measured attempt, not an average.
Does beyla need a GPU?
Not to start. Argusic reached a running state on a machine with no GPU.
What goes wrong when installing beyla?
5 things broke in the recorded run, and 5 were fixed without human help. Each one, and the time it cost, is listed on this page.
Where is the evidence for beyla?
All 2 recorded runs are on this page, each linking to its full log and terminal recording, stored with a sha256 fingerprint so it cannot be quietly altered.
