Steps to Reproduce

config "organizations:dashboards-mep" flag and start service , I report custom metrics with key code below ISpan span = Sentry.getSpan(); span.setMeasurement("video_prepare", preparingTime, MeasurementUnit.Duration.MILLISECOND)

Server receive event in performance panel, but I can not find "measurement.video_prepare" metrics while creating custom widget

Hey unfortunately the Custom Metrics feature is also tied to another new feature known as Dynamic Sampling, which isn't quite ready for Self Hosted instances yet.

Got it, Thanks. Is there any way I can get trial of Custom Metrics feature? Custom Metrics feature is available on service that your Sentry Team deployed. How do you deploy the service? What config do I miss?

Service that Sentry Team deployed, Custom Metrics feature works.

Service that I deployed for test, Custom Metrics feature doesn't work.

Hello, When will this new feature be released on your schedule?

[priscilawebdev]

The Dynamic Sampling initiative was released yesterday and is available to all new customers and opt-in to existing customers. You can read more details on how to opt-in via this blog post https://blog.sentry.io/2022/11/02/a-new-era-of-sentry/#opting-in

@TonyGui7 it seems that this issue is related to this another one https://github.com/getsentry/sentry/issues/40436#issuecomment-1293581297. Can we close it?

[TonyGui7]

Got it. I think it's available to Saas users or customers, but I use self-hosted instead, which hasn't been updated today.

@TonyGui7 it seems that this issue is related to this another one #40436 (comment). Can we close it?

22.11.0 is released today, but custom metrics still can't be selected as aggregate args with self-host. I am wondering whether this feature will never be available on self-hosted or not. I just need a certain answer

[huririri]

https://github.com/getsentry/sentry-docs/pull/6655 Is it available on self-hosted right now？ @wmak @priscilawebdev

[godPaimon]

Is this feature available on self-hosted now? The version I am using is 23.8.0

[narsaynorath]

Hey there @godPaimon, @huririri, and @TonyGui7

I've tracked down this PR which enabled custom metrics in dashboards, but it hasn't been released yet. It was merged on Aug 30th and our latest release was out on Aug 15th. We should be expecting it to be published soon, we release a new version of self hosted on the 15th of each month.

When it comes out, please give it a try and if there are issues please follow up with us in this thread

EDIT: Because this next release has a lot of new changes, we're going to be releasing early next week. You can follow the progress on this issue: https://github.com/getsentry/self-hosted/issues/2345

[godPaimon]

OK, thx

[NikHomann]

We are on version 23.10.0 on our self-hosted sentry, but I can still not select custom metrics for our dashboard. Is there anything you need to enable manually?

[narsaynorath]

@NikHomann just to clarify, are you able to see the custom metrics on your transactions when viewing the events?

[NikHomann]

Yes, there the custom metrics is shown. For filtering in "discover" it can also be used, but not add as a column and also not for a new custom widget.

[narsaynorath]

@NikHomann just letting you know, I'm going to be looking into this.

When you access Discover, there should be a request made to a URL containing measurements-meta, can you verify if that's being called and if it returns anything? That request should contain your custom measurement, but if not that will help me understand what may be happening in your environment

[NikHomann]

@narsaynorath Thank you!

Yes, that request is being made, but the response is empty.

Removing the Product Owner label for now while we investigate this

[zaicevas]

Hi, is there any progress on this issue?

[narsaynorath]

Sorry for the delay, @NikHomann and @zaicevas. I'm having difficulty reproducing the issue. I'm able to run 23.10.0 with a fresh install and send a transaction with the custom measurement. It took some time but I was able to see it in the UI for selecting fields in Discover and Dashboards.

For more information, how many custom metrics are you sending to Sentry? And would you happen to know if there have been any modifications in sentry.conf.py (docs) r.e. the features portion?

e.g. in a fresh install, these feature flags are enabled, do yours match?

SENTRY_FEATURES.update(
    {
        feature: True
        for feature in (
            "organizations:discover",
            "organizations:events",
            "organizations:global-views",
            "organizations:incidents",
            "organizations:integrations-issue-basic",
            "organizations:integrations-issue-sync",
            "organizations:invite-members",
            "organizations:metric-alert-builder-aggregate",
            "organizations:sso-basic",
            "organizations:sso-rippling",

            "organizations:performance-view",
            "organizations:advanced-search",
            "organizations:session-replay",
            "organizations:issue-platform",
            "organizations:profiling",
            "organizations:dashboards-mep",
            "organizations:mep-rollout-flag",
            "organizations:dashboards-rh-widget",
            "organizations:metrics-extraction",

            "projects:custom-inbound-filters",
            "projects:data-forwarding",
            "projects:discard-groups",
            "projects:plugins",
            "projects:rate-limits",
            "projects:servicehooks",
        )
    }
)

[narsaynorath]

Also, the request to get the available custom metrics is filtered by the selected date range, do you know if the events you're looking at fall within that time range? If they don't, then their measurements won't appear at this time
