Using performance’s custom metrics

[present-g]

Using the setMeasurement described here I send custom values, in debug mode the log `Sentry Logger [log]: [Measurements] Adding measurements to transaction' includes the required custom values, but these values are not in the Dashboard, what could be the problem?

SDK sentry/react version: 7.82.0
Self-Hosted version: 21.9.0

Hey @present-g - do you see the custom performance metrics show up in the sidebar of your transaction?

Hi, thank you for reply!

Unfortunately no, there is no Custom Performance Metrics in the sidebar

I found that setMeasurement is available in SDK v7 (May 30, 2022), but I have Self-Hosted v21.9.0 (Sep 15, 2021), maybe the problem is in the outdated version of Self-Hosted

By the way, if I use setMeasurement I see measurements being sent over the network, but if I use captureEvent there is no sending, do you know anything about this?

Example of using captureEvent:

Sentry.captureEvent({
      message: '__TEST_Measurement_001__',
      level: 'info',
      transaction: 'info',
      measurements: {
        'static.value.test.measurements': {
          value: 200,
          unit: 'second',
        },
        ...Object.fromEntries(measurements),
      },
    });

measurements can only be set on transaction events. type: 'transaction'.

Please reach out to https://github.com/getsentry/self-hosted to ask about what self hosted version custom performance metrics are available at.

Yes, thank you, there is a measurements sending, it would be great to improve types so that this field can be specified only with type: 'transaction'

Do I understand correctly that captureEvent is the best way to send several dozen custom metrics at once?

yeah we need to do some work to improve typing here.

Currently measurements are only supported as being attached to transactions, so Sentry.startTransaction is the recommended API.

We are actively working on supporting flushing metrics directly to Sentry! Please see #9691 and getsentry/sentry#58584, we should have something ready for early next year to test with!

Thank you a lot.
