continues profiling in kubernetes

[NissesSenap]

Would it be reasonable to add something like https://www.parca.dev/ to XKF? It's very early days for the product but it's fully of possibilities and I think many people would find it rather useful.

There are a few options: https://o11y.engineering/the-state-of-continuous-profiling-b89cdbdd47f6

• https://parca.dev/
• https://pyroscope.io/
• https://pixielabs.ai/

And probably a few more.

Parca

• Parca currently "only" supports CPU profiling.
• Parca stores all it's data in memory and uses a agent to collect the available profiles through a daemonset.
• It "only" support compiled languages.
• Creators have gotten fonding
• apache 2 license

pixielabs

• They have created there own language based on Pandas (a python library normally used by data engineers).
  • My initial point of view is that this is bad since we already have put a ton of time in to thanos.
• They support allot more things then just profiling. Can get lots of cool things like really nice network monitoring.
• bought by new relic but is a CNCF project
• Roadmap: https://docs.pixielabs.ai/about-pixie/roadmap/
• current languages: Go, C/C++, and Rust

pyroscope

• https://www.ycombinator.com/companies/pyroscope
• Mentiones nodejs in there issue: https://github.com/pyroscope-io/pyroscope/issues/8
• current languages: go, python, eBPF, Java, Ruby, Rust, PHP, .net
• FlameQL looks similar to promQL in many ways.
• Got a grafana plugin that seems to actually make it possible to visualize the flame graphs inside grafana.
• Uses helm chart to deploy https://github.com/pyroscope-io/helm-chart

This might be interesting for nodejs: https://github.com/google/pprof-nodejs
