Hi all, does anyone know if there is a way to get metrics about a worker execution? I am looking for requests, subrequests, and time cpu ms.

I am able to pull it from graphql apis, but I am tracking this information using workers engine, thus I am curious if there is something I could get this data after dispatching worker in my main worker.

Headers of response do not seem to indicate this information unfortunately. Though I have not checked headers from child-worker yet.

Are workflows supported in workers for platforms?

ALECKS•5/6/25, 3:54 PM

was just about to ask the same question

You can see available bindings here https://developers.cloudflare.com/api/resources/workers_for_platforms/subresources/dispatch/subresources/namespaces/subresources/scripts/methods/update/#(params)%20default%20%3E%20(param)%20dispatch_namespace%20%3E%20(schema)

I don’t see workflows yet

I'm trying to run nextjs app (empty, just installation) to compute worker. in deployment i'm getting this kind of errors:
18:13:46.583 npm WARN EBADENGINE Unsupported engine {
18:13:46.583 npm WARN EBADENGINE package: 'next@15.3.2',
18:13:46.583 npm WARN EBADENGINE required: { node: '^18.18.0 >= 20.0.0' },
18:13:46.583 npm WARN EBADENGINE current: { node: 'v18.17.1', npm: '9.6.7' }
18:13:46.583 npm WARN EBADENGINE }

is there anyway for me to control which version of node the server is using? looks like it is out of my control.
thanks.

Roncho•5/7/25, 10:21 PM

I found where I can set the Build system version, both preview and production are on "version 2" which is node 18.17.1, pretty old, but I don't see a way to change that.

you could try using a tail worker https://developers.cloudflare.com/cloudflare-for-platforms/workers-for-platforms/configuration/observability/#tail-workers

Cloudflare Docs

Observability

Workers for Platforms provides you with logs and analytics that can be used to share data with end users.

has anyone tested this? If not I might give it a try to see if it works

Vlad LykhonisOP•5/12/25, 8:23 PM

I used analytics but it doesn’t scale as it is only 300 requests per 5 mins! There is also no meta results similar to D1 after dispatching a worker. I feel like having a meta info as a part of a response after dispatching a worker is the way to go. I will look into tail worker, but it seems like a quite a workaround from a Quick Look based on what I need.

Ddarkpool has anyone tested this? If not I might give it a try to see if it works

Vlad LykhonisOP•5/12/25, 8:24 PM

I didn’t bind workflows, but D1 and few other resources just fine.

yeah same. I have user workers calling tools exposed by workers outside namespace so going to give workflows a shot later

ill let you know

ruan•5/14/25, 9:27 PM

why the header mf-original-urlmf-original-url only exist when debugging a worker locally with wrangler?
when i deploy it to cloudflare the header is missing

example:

export default {
    async fetch(request, env: Env): Promise<Response>
    {

        request.headers.forEach((value, key) =>
        {
            console.log(key, value); // prints mf-original-url only locally 
        });

export default {
    async fetch(request, env: Env): Promise<Response>
    {

        request.headers.forEach((value, key) =>
        {
            console.log(key, value); // prints mf-original-url only locally 
        });

Peps•5/14/25, 11:00 PM

Is there a reason you need that header? It's only used internally by Wrangler when using the local dev mode

Could you recommend another Cloudflare option I could add?
As I mentioned, I currently have APO, and two days ago I subscribed to Argo, but I haven't noticed any difference.
My content is mostly static, and I update it every 2 days by adding new pages to the existing content.

The only thing you can really do is take advantage of the CF cache but if the backend you use is slow its going to be slow at times

Please use the /link command to authenticate with your Cloudflare account and link it to your Discord user. This helps Cloudflare employees access your details more quickly and provide support. It also makes future support requests easier, since your account will already be linked.

aabb•5/20/25, 5:42 PM

Hello there,
I'm sorry to hear you are having trouble logging into your account.
We're happy to help you regain access by temporarily removing the email factor authentication requirement.
To help us confirm you’re authorized to make this change, perform one of the options below:
Option 1: Create a file on your web server.
Please create a file at /.well-known/cf-2fa-verify.txt with the following content for 5 of your active domains (or all your active domains if you have less than 5): (/.well-known/cf-2fa-verify.txt for example)
S6TnbBap4SoiS9NcL4K9
After completing this task, verify that the URL works and that the token is correct.
Your server must be configured to serve files from hidden directories. If /.well-known is treated specially by your webserver configuration, you might need to modify the server configuration to ensure that /.well-known/cf-2fa-verify.txt is accessible.
Option 2: Add a Meta tag to your homepage.
In the header of your homepage for 5 of your active domains (or all your active domains, if you have fewer than 5), add the following before the closing HTML </head> tag:
<meta name="cf-2fa-verify" value="S6TnbBap4SoiS9NcL4K9" />
Verify that you can see this meta tag in your homepage. For security reasons, this must be on the homepage at the root of your domain.
NOTE: If you have a Cloudflare Pages implementation, you can add the above meta tag or file to your Github repo. It will then be deployed to Pages automatically.
After Completion
After you've added this token, reply to this case letting us know on which zones you've added the txt file or meta tag, and we'll be able to proceed.
We appreciate your understanding. Thank you for being part of Cloudflare.

Best Regards,
Luis Pedroza | Technical Support Engineer
