Observability in WebAssembly (opens in new tab)

This is by the same team behind Extism, a WASM plug-in library implemented in multiple languages. I’ve been active on their Discord and they’ve been really awesome and supportive of any questions I have. I’m excited to see where they go with this observability SDK. WASM has a major usability problem right now, and we need things like this and Extism to make it smoother to produce and consume wasm programs!

I wonder how well (or if it's even possible?) to pair this with hosted WASM runners (like CloudFlare Workers, or Fastly Runners, etc.).

It looks like there is also (limited?) support for tracing functions and allocations in WASM binaries you didn't compile. I'm looking forward to trying this out!

Great to see more focus on observability for Wasm now. This was a major impetus and still a major goal of the Wizard Research Engine, which has engine-level hooks that allow programmable instrumentation.

Not sure if OP is from Dylibso, but would love to see telemetry data emitted in OpenTelemetry format as well so different tools (including open source ones) which support Otel format can also consume this data.

I am one of the maintainers at SigNoz [1], an otel native open source observability platform and would love to enable our users to see telemetry data from WASM

Was just thinking of something like this last night. Now, wonder if I can compile JS and automatically wire up apm for all spans.

I love this. I wish it supported something self-hosted like Jaeger though.

Extract logs, traces, and metrics from Wasm!

What a crazy choice of background color. On the other hand it kinda signals that the developers themselves designed it which is generally a good sign of other characteristics of a project.
