k6browser: too many time series recommendation

[inancgumus]

What?

Users may generate too many browser URLs and encounter too many time-series errors. We may support these users and provide a workaround for using page.on('metric'). However, it's a common problem for many browser tests. And it's not easy for users themselves to figure it out. Unlike HTTP URL grouping, there's no dedicated section in our docs that explains this problem and how to solve it.

I left a few small comments here, thanks for creating this new page @inancgumus. 🙇

Two things outside of the comments:

• What do you think of adding a mention of this new page to page.on()?
• Could you please also add these changes to the v1 docs?

Also, please let me know if you'd like me to make any of the changes I suggested to the PR, I'm happy to do it as well. 🙇

Hi @heitortsergent,

Adding a mention of this new page to page.on()?

Yes, that makes sense 👍

Could you please also add these changes to the v1 docs?

Done. I've also updated the versions between v0.55 - v1.

let me know if you'd like me to make any of the changes

Yep, sure ❤️ That would be great 🙇
