will otel traces be viewable in the cloudflare dashboard at some stage? currently i'm using baselime (was using honeycomb) - but also looking at other options if anyone has recommendations

mattOP•1/26/25, 1:05 AM

in baselime how do you customize how spans appear? some have cloudflare/http/nodejs icons etc

mattOP•1/26/25, 1:06 AM

ah i think it's because im using the newer semconvention attrs, need to go back to the old ones ie. ->

Currently there is a limit of 128kb of data limit for each workers invocation.

The sample rate works on an invocation by invocation basis.

i.e. a sample rate of 30% means you will get all the logs for 30% of your invocations and 0% of the logs from the rest.

To fix this you want to look at consolidating your logging for each invocation and make sure you are not logging unecessary data.

Hope this helps

It would be nice to have everything in one place, I thought with the addition of worker logs that CF might be aiming to support the other 2 OTEL signals (metrics and trace spans)

Hello!

I have a question about tail workers.
We want to balance what is best between good DX and easy integration.
Currently if I understand correctly, each worker should have its own tail worker?
Because we are thinking to create 1 tail worker handling all our workers. For logs it's fine, but for sentry it makes it very complicated as this one tail worker should have knowledge about all the sentry DSNs...

What would be the recommended way? Note: we are using a monorepo

Bboristane your assessment is correct. I've used a single tail worker attached to multiple ...

So would you say it is a better practice to instead have 1 tail worker per worker?

That's at least what seems to suggest the documentation

James•1/31/25, 9:44 PM

feature request: it'd be nice to be able to get a breakdown quickly in the overview of number of obs events per worker to see which ones are doing the most https://i.james.pub/file/2025/01/df95b736-f971-4d8a-bee6-4680466f1b9a.png

James•1/31/25, 9:44 PM

even if I click into a worker, I don't see a clear and easy way to get counts over a period of time without adding up all the events in the graph myself manually

ssandler•2/3/25, 6:22 PM

Any advice for using the https://github.com/evanderkoogh/otel-cf-workers with Durable Objects? The examples given don't seem to work with the current SDK, because they don't but rather implement it as an interface. Trying to run that yields a runtime error

I was wondering if I could get some assistance on our baselime account which appears to be acting very buggy.
We saw some strange behaviour in the dashboard when our admin tried to give admin status to another team member.

This removed admin status from everyone and now we are all “contributors”. I’m not sure if these problems are connected but we also started seeing that our query pages were failing. When we would try going into a query it would flash something useful and then immediately go to an empty screen. Essentially we would see some UI and then it would almost immediately go blank.
Our dashboard right now has gone completely empty - we have zero environments and no logs displaying

Hey there,
Do you know if @opentelemetry/sdk-trace-node works correctly in cloud flare worker?

I have been trying to make automatic instrumentation via otel-cf-workers work, but for my usecase (one service spawns others via queue produce/consume) I just cannot make it work correctly, so if possible i would just like to manually configure the tracing.

It does not. If you want a 3rd party solution this is great https://github.com/evanderkoogh/otel-cf-workers but its worth reading through the issues and making sure you don't need something that doesn't currently work

I believe the worker log dashboard is broken in loading more
No matter time frame, it returns a few log lines and cannot load more when scrolling bottom

mihaaai•2/24/25, 10:15 PM

Is it possible that CF is dropping packages if 2 requests (2 websocket messages exchanges in my case) between my origin and a Durable Object happen too fast?
I'm sending 2 messages at 8 to 10ms distance between each others and they don't appear in Logs and the Durable Object is not responding back to my origin.

When adding some ms timeout on the server it picked them up correctly

RenderZ•2/26/25, 2:05 PM

I recently connected my OTEL setup to Baselime via the OtplExporter in .NET. I've got everything working, except for the traceId and spanId. I'm sending the correct traceId and spanId to Baselime, but it somehow turns it into a comma-separated byte array? This is causing the logs to be disconnected from the traces. Does anyone know how to fix this behaviour?

Observability Logs get disabled every time we deploy a Worker via QuickEdit, which Where is the wrangler.toml file ?. Any chance we could get this fixed, please?

Peps•3/4/25, 2:34 AM

Something I miss in the new Worker metrics is seeing the p50, p75, etc for request duration. I feel like that would be useful more than the p50 and such from wall time, as request duration is what's actually visible to the end-user.
Would love to get more insights in the metrics that actually affect my users
