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.

Okay, I've checked. it doesn't. Some runtime errors appear when trying to execute the sdk initialization. Unless I did sth wrong.

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

Yeah, this is what i wrote in first message i had been using, but it does not properly instrument queue interaction, and also somehow makes it giga hard to manually extract tracing context from custom sources (eg queue message payload)

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

Peps•3/4/25, 2:41 AM

Also not sure if it's a bug, but this docs page mentions

Worker metrics can be inspected for up to three months in the past in maximum increments of one week.

which seems to outdated, as you can now view up to a month. Also it seems like you can't go past a month in the dash at least, because trying to look further than a month ago gives Query time range is too long.Query time range is too long.

Peps•3/4/25, 2:41 AM

Also not sure if this is a bug, but clicking the calendar icon in the time range does nothing. I would assume that clicking it would've shown a date/time picker, but nothing happens

Peps•3/4/25, 2:42 AM

Another bug (sorry) - The zoom in/out button from the map is overlapping the time range dropdown

rohin•3/4/25, 3:02 AM

thanks for all the bug reports, we'll take care of them (quick edit, map component, docs pages should reference 1 month metrics retention)

BenG•3/5/25, 4:30 PM

Not sure if this is the right channel but approximately how long do metrics take to update, the logs seem to be real time

Hey everyone, how can I implement baselime into my nextjs app hosted on cloudflare pages? I found this example for sveltekit, but nothing for nextjs: https://baselime.io/docs/sending-data/platforms/cloudflare/pages/#sveltekit. I also found this: https://baselime.io/docs/sending-data/languages/next.js/ but i'm not sure how I would change this to work on the edge. Lmk if anyone can help me with this.

but then i'd only be able to log info in the middleware right?

mihaaai•3/7/25, 8:41 PM

Hey, I was wondering if there is any project in the wild to orchestrate workers in the local environment.
As my app grows, I find myself working with 10-15 microservices each one corresponding to a worker connected to others by service bindings.
This is getting annoying to develop on dev since I need to start as many terminals at once on my localhost and (although they are connecting through each others) it's kinda hard to keep track of all off them,.

I was wondering if there is something like an orchestrator to start all of them in parallel and maybe share logs across a single or nicer interface, I understand this is no small task to develop but if there is already a poject of such I'd love to know and also to contribute to

KKenny but then i'd only be able to log info in the middleware right?

AGill•3/7/25, 11:19 PM

that's true maybe just a logger util method that takes in router context and returns a logger instance, like useLoggeruseLogger. That's what I'm using (Nuxt3):

import { BaselimeLogger } from '@baselime/edge-logger';
import type { H3Event } from 'h3';

export function useLogger(event: H3Event) {
  const { baselimeApiKey: apiKey } = useRuntimeConfig(event);

  const logger = new BaselimeLogger({
    apiKey,
    ctx: event,
  });

  return logger;
}

import { BaselimeLogger } from '@baselime/edge-logger';
import type { H3Event } from 'h3';

export function useLogger(event: H3Event) {
  const { baselimeApiKey: apiKey } = useRuntimeConfig(event);

  const logger = new BaselimeLogger({
    apiKey,
    ctx: event,
  });

  return logger;
}

Kenny•3/7/25, 11:19 PM

Super cool, thanks

Phong Phan•3/8/25, 10:01 AM

Hi there,

Can we use Baselime as standalone service without using CF Worker? Also, I just invited my teammates to the platform but they didn't get any emails.

What are you logging that is over 128KB? At that point any text you log is likely to run into issues even rendering in the log viewer

Isaac McFadyen•3/10/25, 11:44 AM

128KB of text is a lot

Sean•3/14/25, 4:29 PM

Is there any way to arbitrarily query logs, or is it limited only to viewing through dashboard UI? I'd like to be able find out things like number of requests that resulted in status codes (200, 4xx, 5xx) for a given time frame? Or even just number of log messages matching a filter, etc.

I believe the quick-copy feature on the logs dashboard has a problem. Instead of the text value,
"undefined" is copied

you'll see some improvements releasing in the coming weeks. check out the new invocations view & send feedback our way!

the new sidebar when you click on an invocation is very cool

Eengrtitus Yes, tried that. It doesn't show immediately as well. All the console logs dont

are your invocations lasting 30 mins?

what’s the difference between the errors in the monitoring dash and the errors in the logs? I’m not sure why I wasn’t seeing any errors on the logs page

DanB•3/16/25, 6:46 AM

@kchro3 I also see this bug with the timestamps . The hover popup shows the correct timestamp, and the log line shows 4 days backwards.
I think this requires the attention of someone from cloudflare team

onetwoDom•3/16/25, 6:55 AM

hello, loving the new Invocations tab! thank you for adding it. Just an idea to add country (flag or code) as an additional tab, to quickly see if longer wall time is due to a request being distant from db
