Hey lovely CF people.. I am having a proper challenge building the Open Telemetry library and auto-instrumenting it, because you are implementing exactly the same interface as say a service binding (a

fetch

fetch

method), but at least in your documentation you instruct people to invoke that in a way that is not spec compliant.

This leads to two problems:
1) I can't (easily) distinguish between a ServiceBinding and a BrowserRendering Binding
2) When I try to create a

Request

Request

out of the parameters you specify (

/v1/acquire

/v1/acquire

/v1/acquire

/v1/acquire) it (obviously) fails because

/v1/acquire

/v1/acquire

/v1/acquire

/v1/acquire is not a valid URL.

Now #2 can probably be easily solved by passing in a proper URL, but that would just prevent things from crashing.

Technically I could solve #1 by instrumenting any

fetch

fetch

function with a generic wrapper and then decide which instrumentation implementation to use based on the parameters passed into the

fetch

fetch

function, but that would be pretty brittle, because I would have to hardcode exactly what you would pass into the first request.

The puppeteer library can easily add support for instrumentation by just using the OTel API functions. That will be picked up by this library and be automatically added.

jason•11/7/23, 2:39 PM

Hello, I'm trying to understand the proposed pricing structure and how to optimize it. Based on the proposed pricing in this blog post[1], you get 500 sessions per month for free and then 10 cents per session after that. A session, as I understand it, is an active running browser. The naive approach, at any sort of scale, quickly becomes expensive. So the blog says to use a durable object to keep the browser alive and re-use the existing session instead of starting a new one. The example code uses an alarm to keep the browser alive while idle for 1 minute before shutting it down. Using this structure, If I'm understanding it right. Worst case scenario, if I had a job that triggered every 61 seconds, I'd end up starting about 1440 sessions per day. Which is $144/day or over $4k/mon. That's expensive. So, the solution would be the extend the life of the durable object to, say 2 minutes, which would reduce the $4k to $0, for the browser cost.

However, the durable objects aren't free, but I'm having a much harder time understanding how expensive they will be. For example, why do I need to shut down the browser at all? How much does it cost for the browser to sit idle in a Durable Object? Is that documented anywhere? And what if it's not idle? If my worker is handling 1 request per sec, so the browser is in active use all of the time, what sort of costs is that going to yield for the DO?

Any information would be appericiated.

As far as understanding the pricing I've got no clue and there hasn't been any real clarification on that. Not a single use case makes sense to pay $4000 per month for a single browser instance. You could hire a human for that.

Some people were mentioning that having one session open, means one request at a time, but that's not true. You can use

newPage()

newPage()

newPage()

newPage() to use the same browser to process request async - but there's got to be some limit to that. I can't imagine one browser would do 100s of request simulateously. But again, those limits don't seem documented either.
