Only collect RUM sessions with at least 1 error

[vladholubiev]

Right now we have lots of sessions collected. Only <1% of them have some error.

I'd like an option to configure RUM to send sessions if an error/exception happens on the client-side.

This will allow reducing spend greatly.

Hi @vladgolubev

Currently we can't reliably store all events of a session until some event happens. We are working on 2 solutions for this:

• Enabling Error Tracking for browser logs: you will get the ability to only send error logs and see them turned into issues in Error Tracking
• Tail-based sampling: you send us 100% of the data at a low price and pay the normal price for interesting sessions (at least 1 error, bad performance, interesting user actions...)

These 2 items are on the roadmap although we can't share any ETA for now.

@hdelaby, as this was ~6 months ago, I'm curious if "Enabling Error Tracking for browser logs" is still on the roadmap. We're comparing Sentry to Datadog, and as Sentry charges based on the number of error events, to get all errors with datadog we'd need 100% sampling which is the difference between ~$1k and ~$85k for us.

@hdelaby is there any update on this issue?

We are considering migration from sentry to datadog, and this issue make us frustrated because of cost issue

It's the 3 year anniversary of this issue being created, so I need to ask for an update as well now please. We want to use Datadog for effective tracking, but this issue is stopping us due to the phenomenal cost difference between being forced to track every single session to catch errors, and only storing "interesting" sessions with errors. Setting the sample rate lower and therefore missing errors is not an option.

Hi,

We are currently working on a feature that should help on that front. No precise ETA to share for now but stay tuned.

Hi @bcaudan, any further updates? Having an option to make RUM send sessions if an error/exception happens on the client-side would also be quite helpful for my project

Hi @arcticmatt, Unfortunately we do not have an ETA yet, but this is something that we're actively working on. Thanks for your patience
