Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

Continuous profiling tools such as parca may be worth looking into for your use case.

Hi everyone, How could you find the lines executed for a particular method call in any language (java, go..) using eBPF?
They were bought by Elastic, maybe they'll open source it. There's also https://github.com/parca-dev/parca
-
How do you monitor your Go apps?
an alternative option to pyroscope to do continuos profiling in production could be parca.dev check and here
- Go garbage collector doesn't release memory

How to observe an http web application in real time with pprof?
+1 to Parca.dev https://github.com/parca-dev/parca as continuos profiling tool in production

Continuous Profiling in Kubernetes Using Pyroscope
Parca collects, stores and makes profiles available to be queried over time. It is open source and can be deployed on production environments as Parca focuses on sampling profiling two main types of profiles: tracing and sampling.

Launch HN: ContainIQ (YC S21) – Kubernetes Native Monitoring with eBPF
Polar signals develops Parca [0] which is another eBPF observability tool, and Isovalent develops Cilium [1] which is built on eBPF as well. Genuinely curious if there are differences, or if eBPF only allows for specific observability functionality and each tool has it all.

Dwarf-Based Stack Walking Using eBPF
Thanks!
As @brancz mentioned, Delve uses DWARF unwind information to produce backtraces (they are stored in the .debug_frame section for Go).
You are right, Go enabled frame pointers for all architectures as of 1.17 [0]. This is enabled to allow profilers to work well, without having to use to techniques such as the one we describe in our post.
When it gets funny is that there's `gopclntab`, a 3rd option in Go to unwind stacks, used by `panic` and I believe other parts of the runtime. If you are interested in more details, Felix Geisendörfer's repo contains way more details [1]
