The only thing that I know of which has accurate duration on a per-request basis is the HTTP Requests dataset on Logpush - which is an Enterprise feature

kian•5/28/23, 1:23 AM

Workers for Platforms will probably have better metrics, as customer Workers is one of the main use-cases for it, but that's also currently Enterprise but is likely to come to pay-as-you-go plans eventually.

kian•5/28/23, 1:23 AM

Timing in Workers is always difficult as every timer you have accurate to (including the timestamps in the live logs) implements Spectre mitigations.

kian•5/28/23, 1:24 AM

It only advances on I/O - so it's never representative of wall-clock anyways.

SoulHarsh007•5/28/23, 2:08 AM

is there a way I can get execution region from my worker?

WalshyOP•5/28/23, 2:09 AM

request.cf.colorequest.cf.colo

WalshyOP•5/28/23, 2:10 AM

or request.cf.regionrequest.cf.region for more region like info

WalshyOP•5/28/23, 2:10 AM

for details on all the available properties: https://developers.cloudflare.com/workers/runtime-apis/request/#incomingrequestcfproperties

WalshyOP•5/28/23, 2:12 AM

there are no "regions" in CF though so yeah meowupsidedown

SoulHarsh007•5/28/23, 2:20 AM

And this works in a cron job too?

SoulHarsh007•5/28/23, 2:22 AM

I mostly want it for my cron jobs, since I want to know which region executed the cron. I was also wondering if it might be possible to run the same cron job, from multiple regions at the same time?

WalshyOP•5/28/23, 2:28 AM

err no in cron we don't expose that easily but you can hit /cdn-cgi/trace to grab it

const res = await fetch('https://cloudflare.com/cdn-cgi/trace');
const text = await res.text();
const colo = text.substring(text.indexOf('colo=') + 5, text.indexOf('\n', text.indexOf('colo=')));

const res = await fetch('https://cloudflare.com/cdn-cgi/trace');
const text = await res.text();
const colo = text.substring(text.indexOf('colo=') + 5, text.indexOf('\n', text.indexOf('colo=')));

SoulHarsh007•5/28/23, 2:33 AM

Thanks

SoulHarsh007•5/28/23, 2:34 AM

And can I run same cron in multiple regions at the same time?

WalshyOP•5/28/23, 2:37 AM

not natively but there's a few ways to do it:

Healtchecks - you can run these from multiple regions, simply have them hit your Worker
Durable Objects - create them in what regions you want then call them in your cron Worker

SoulHarsh007•5/28/23, 2:42 AM

thanks again

this is what I do but our sourcemaps have been pretty hit or miss. lots of time there is no context or it's incorrect

WalshyOP•5/28/23, 7:30 AM

I'd look at your code honestly, it's been working great for me both in personal and work projects

sathoro•5/28/23, 8:19 AM

I think it's mostly when manually doing sentry.captureExceptionsentry.captureException and also sometimes when there is an error deep in a library then there is no context

sathoro•5/28/23, 8:22 AM

actually I have a great example from yesterday because it is from the same webhook route

sathoro•5/28/23, 8:23 AM

missing stack trace (only shows the library code)

sathoro•5/28/23, 8:24 AM

actually I don't want to show screenshot of the second one but its code in the same route itself that manually calls throw new Errorthrow new Error and the full stack trace is there

sathoro•5/28/23, 8:25 AM

the other issue I get is with errors sometimes not de-duplicating themselves. is this something I need to config differently?

sathoro•5/28/23, 8:27 AM

also with some DO errors I sometimes get errors like this with zero stack trace. I think itty-durableitty-durable is probably losing the context somehow since they use a proxy object or something. this one does get de-duplicated though

PencilNavigator•5/28/23, 9:13 AM

guys all my workers just got about 200-2k requests all at 9:00 together

PencilNavigator•5/28/23, 9:13 AM

what kind of wierd issue is this

PencilNavigator•5/28/23, 9:13 AM

by all i mean all worker service deployed in my account

Ian•5/28/23, 3:06 PM

What's the best way to store logs from workers thonk

, current options seems to all require either R2 or an external destination to store them, with each storing costing a R2 write

WalshyOP•5/28/23, 3:10 PM

logpush is the way and r2 is one option. You can also use others though like Backblaze which would be cheaper

They're batched and sampled (depending on your option) so you don't pay per request but yeah, it will likely cost a write at wherever you store
