Metrics (Trace Connected) in Open Beta

[Dhrumil-Sentry]

We’re introducing Metrics that let you send counters, gauges, and distributions from your code to track things like email.sent, checkout.failed, or queue.depth — and pivot directly into the related traces, logs, and errors when something looks off.

TraceConnectedMetrics.mp4

Get started with sending metrics from JavaScript or Python projects with these docs: https://docs.sentry.io/product/explore/metrics/getting-started/

Why we built this

Metrics in most tools stop at charts — they show that something changed, but not why. When a checkout.failed counter spikes, you’re forced to switch tools and manually line up logs or traces to find the cause.

With Sentry, every metric event carries a trace_id.

That means you can:

• click into a sample and see the exact trace that produced the metric,
• open the related spans, logs, and errors,
• understand why the metric moved — slow database query, failed API call, bad deploy, etc.

So instead of “metric alert → guesswork,” debugging becomes a single flow: Metric spike → open a sample → trace waterfall → root cause.

How the UX works

Aggregates tab shows trends and totals across any attributes (e.g. sum(metrics_value) grouped by email_type).

Samples tab shows individual metric events with direct links to their trace — so you can jump straight into the logs, spans, and errors that occurred at the same moment. Allowing you to drill into any spikes or dips in your metrics and find relevant errors,traces or logs to look at.

How to get started

If you'd like access please comment with your org slug below or drop us a note at feedback-metrics@sentry.io

Python

You need to be on a min version of 2.43.0 of our Python SDKs

import sentry_sdk
from sentry_sdk import metrics

sentry_sdk.init(
    dsn="___PUBLIC_DSN___",
    _experiments={
        "enable_metrics": True,
    },
)
metrics.count("checkout.failed", 1, attributes={"route": "/checkout", "tenant": "acme"})
metrics.gauge("queue.depth", 42, attributes={"queue": "emails"})
metrics.distribution("cart.amount_usd", 187.5, attributes={"currency": "USD", "tenant": "acme"})

More details: getsentry/sentry-python#5042

JavaScript

You need to be on a min version of 10.20.0 for our JavaScript SDKs

Sentry.init({
  dsn: '<your-dsn>',
  _experiments: { enableMetrics: true },
});

// Counter — increment a metric (defaults to +1)
Sentry.metrics.count('checkout.failed', 1, {
  attributes: {
    route: '/checkout',
    tenant: 'acme',
    provider: 'stripe',
  },
});

// Gauge — set a current value
Sentry.metrics.gauge('queue.depth', 42, {
  unit: 'items',
  attributes: {
    queue: 'emails',
    region: 'us-east-1',
  },
});

// Distribution — record numeric values to compute p95, avg, sum, etc.
Sentry.metrics.distribution('cart.amount_usd', 187.5, {
  unit: 'usd',
  attributes: {
    currency: 'USD',
    tenant: 'acme',
  },
});

Each metric event includes:

• name, kind, value, attributes
• trace_id, span_id → used to link with other telemetry
• optional unit, byte_size

More details: getsentry/sentry-javascript#18055

When (and why) to use Metrics

Metrics are best for application and code based health signals — numeric indicators of whether your application logic is behaving as expected.

You should reach for metrics when you want to quantify what your code is doing

Examples:

• email.sent / email.failed
• job.processed / job.retried
• checkout.started / checkout.failed
• payment.declined / refund.issued
• queue.depth / pool.in_use
• search.zero_results

Feedback

We’re working on shipping Alerts, Saved Queries and dashboard widget building support very soon

We’d love to hear your feedback about the following

• Are the SDK APIs easy enough to send your desired metrics ?
• Any feedback about the Metrics Explorer UX - What could make this a better experience for you ?
• Any default metrics that you’d like Sentry to send automatically

[mohitpatel-ghl]

@Dhrumil-Sentry We would like to try this out
This is our sentry org url https://gohighlevel.sentry.io/

[Dhrumil-Sentry]

@mohitpatel-ghl - That was a bug in the copy we're showing - It's supported for all JS platforms - please see the SDK instructions here: getsentry/sentry-javascript#18055

[mohitpatel-ghl]

Any default metrics that you’d like Sentry to send automatically
@Dhrumil-Sentry

We want to track the heap memory consumption, sometimes on users side page is becomes unresponsive or crashes due to excessing memory consumption.
We already have the logic on our code which computes memory at every certain interval, i'm just thinking if this metric feature could be a good approach to log it to sentry & then analyze it over there. Any suggestions over here in respect to metrics feautre

[Dhrumil-Sentry]

@mohitpatel-ghl Given you already have the logic to compute this - you can add this as a distribution metric so that you can track the p50,p90 of memory consumption across users. Def a good use case for metrics

[mohitpatel-ghl]

And @Dhrumil-Sentry does this metrics feature depends on any sampling like trace sampling rate or any other. Because sometimes we observed that all data is not being logged on dashboard

[Dhrumil-Sentry]

@mohitpatel-ghl the trace sample rate only applies to spans and not to these metrics. There can be a few mins of delay in us ingesting metrics and making them available to query. You can also go to the Stats page in the Org settings and select Metrics and confirm nothing was dropped on our server side.

If you still think any data is being dropped - Can you please open an issue here: https://github.com/getsentry/sentry-javascript/issues - we'd need a few more details from you to be able to debug

[eddie-at-stan]

stan-yz please! This came just in time.

[Dhrumil-Sentry]

@eddie-at-stan you should have access now -Would love to hear any feedback !

[TwoTau]

I'd love to try this! Our org slug is scorecard

[Dhrumil-Sentry]

@TwoTau You should have access now

Here's the JS: getsentry/sentry-javascript#18055 and Python: getsentry/sentry-python#5042 SDK instructions

Please let us know if you hit any friction

[pshomov]

Will you support high cardnality attribute values - user id, tenant id, etc.? What will you consider as a billable metric item?
Would love to try this 🤩 . Our org slug is spectaflow.

[Dhrumil-Sentry]

@pshomov We're using a high volume event store for this solution - So we can definitely support high cardinality values like user_id etc.

We don't know pricing details yet but there will be no charge to using these Metrics while we're on Open Beta for a few months atleast.

I will say that the solution is mean to help developers track metrics with high cardinality tags and we're more likely to restrict how many attributes you could attach vs causing a cost explosion due to high cardinality - But all of this is TBD and we'd appreciate any feedback

Your org has access now. Here's the JS: getsentry/sentry-javascript#18055 and Python: getsentry/sentry-python#5042 SDK instructions

Any feedback appreciated !

Great thanks! Will give it a try

[leoht]

@Dhrumil-Sentry Just tried to implement a few metrics (using the Python SDK), though it seems they're not showing up in the UI at all. I'm still only able to see the default landing page with the tutorial/demo, though I'm able to see the corresponding trace in the UI.

What's the best way to give feedback on this one? Happy to open an issue

[Dhrumil-Sentry]

@leoht Can you please leave a comment on the Python SDK discussion with an example of a metric you're sending with the SDK: getsentry/sentry-python#5042

We'd need the version of the SDK you're using as well 🙏 - Thanks a lot for sharing feedback

[gaurav-peswani-truva]

We really want to try this out. Can we please get access for the organization truva?

[gaurav-peswani-truva]

Also are the metric examples mentioned in the description the only supported values or we can send any key as desired? We are planning to use this for sending Prisma metrics mentioned at https://www.prisma.io/docs/orm/prisma-client/observability-and-logging/metrics.

[Dhrumil-Sentry]

@gaurav-peswani-truva You should have access. Please see these docs to get started: https://docs.sentry.io/platforms/javascript/guides/nextjs/metrics/

You can send any counter/gauge/distribution type metric using the Sentry SDK - the examples I mentioned are only representative

Let us know if you hit any snags

[Dhrumil-Sentry]

We've shipped support for dashboard widget creation ! You can directly create dashboard widgets from your Metric queries

You can add Metrics charts etc from the widget builder directly too using the Metrics dataset

[Dhrumil-Sentry]

We've also shipped support for the Go SDK. Please see these docs to get started: https://docs.sentry.io/platforms/go/metrics/ !

[softworkz]

What's the plan for the .NET SDK?

• Any default metrics that you’d like Sentry to send automatically

• CPU usage - application + system total (percent)
• CPU usage - application + system total (percent, for the GPU driving the primary display)
• RAM usage - application(shared/private) + system total (percen + absolute)
• Network IO - send, receive, total,(absolute)

[Dhrumil-Sentry]

@softworkz the .NET SDK is being worked on - Here's the tracking issue: getsentry/sentry-dotnet#4741

Thanks for this list of metrics !

[KarlBuckler]

Hi @Dhrumil-Sentry
hsmb-o0 would like to test it. Thx 👍

[Dhrumil-Sentry]

@KarlBuckler You should have access already - Please see these docs to get started: https://docs.sentry.io/product/explore/metrics/getting-started/

[rizvanJacob]

Hi! would love to test this. My url is https://tappytunes.sentry.io and I'm running a react native project. I've set up the SDK following the guide, but I don't see Metrics on the Explore page. Wondering if I need access to see it?

[Dhrumil-Sentry]

@rizvanJacob we had a bug with feature flagging related to react native projects - We've fixed it and you should see Metrics under Explore now

[rizvanJacob]

Awesome! I got it. Thanks (:

[Dhrumil-Sentry]

We've shipped support for iOS and Flutter SDKs ! Please check these docs for iOS and Flutter.

[asyd]

Hello there! Is there a way to test this feature in a self-hosted deployment?

Cheers

[Dhrumil-Sentry]

We generally publish self hosted support once the feature is generally available which is likely to happen by end of April

[thomaseizinger]

Are there any updates around the Rust SDK? getsentry/sentry-rust#938 doesn't mention anything and there also doesn't seem to be any activity on the PRs.

[Dhrumil-Sentry]

We're not actively working on Rust right now - it's one of our very lesser used SDKs so we're waiting on some more community feedback asking for it for prioritization

[thomaseizinger]

Okay thank you! Please take this as a request for prioritization then. We are very happy with Sentry for monitoring our customer-deployed apps and would love to gather metrics around how they perform via the same platform.

[cjtheham]

Are there any updates on when Metric Alerts will be available?

[Dhrumil-Sentry]

@cjtheham Very soon - We should have support rolling out in the next 2-3 weeks 🙏 Thanks for your patience

[patrickdundas]

@Dhrumil-Sentry - team is anxiously waiting for this. I see Metrics Alert Config documented here now, but not available in my account yet. Does my account need to be opted-in to this alert option (we are already in the Metrics Beta)

[zackkitzmiller]

z19r and hexagon-tickets please? This is basically exactly what we're looking for right now in both orgs.

[bcoe]

@zackkitzmiller you should have access to Explore > Metrics. Let us know if that's not the case, or you bump into any problems?

[Syed-RI]

Usage quota and billing? Are they still TBD? What are we thinking of? Size ? Number? Event? 🤔

[alexjillard]

@Syed-RI We're still working through the specifics, so no concrete details to share yet. We'll get pricing details out as soon as we can, though.

[carlos-musetti]

Hi! We would love to test this at firmstudio

[alexjillard]

Hey @carlos-musetti, you should have access now. Take a look at the getting started docs, and please send us any feedback you've got!

[martinbean]

Hi. I’m a little unsure on how “counters” work.

Say I create a counter with the name test-counter. Day 1, I send a count of 5. Day 2, I send a count of 7. Will these counts be summed, or will the new count (7) replace the old count (5)?

[The-LukeZ]

.gauge ist for "setting" the value and .count is for adding X to an already existing count (starts as 0).

[martinbean]

So I’ve just emitted my first gauge, but it seems Sentry wants to group it by either second or minute, or aggregate it using a function like min, max, or avg.

Is there no way I can just emit a value and say, “This metric’s value was X at this date and time?” Basically, I want to record counts of records (e.g. users) so I can see how that count’s gone up or down over time; not aggregate it or group it.

[drxcheng]

Can you enable for "thoughtexchange" please? Thank you!

[TeTiRoss]

hey, when this feature is expected to be rolled out, along with alerts?
we are looking into using Sentry and Metrics is the main thing that we would need.
