Releases & Health
A release is a version of your code that is deployed to an environment. When you give Sentry information about your releases, you can:
- Determine issues and regressions introduced in a new release
- Predict which commit caused an issue and who is likely responsible
- Resolve issues by including the issue number in your commit message
- Receive email notifications when your code gets deployed
Include a release ID (often called a "version") when you initialize the SDK.
The release name cannot:
- contain newlines, tabulator characters, forward slashes(
/) or back slashes(
- be (in their entirety) period (
.), double period (
..), or space ( )
- exceed 200 characters
The value can be arbitrary, but we recommend either of these naming strategies:
- Semantic Versioning:
packageis the unique identifier of the project/app (
versionis the semver-like structure
buildis the number that identifies an iteration of your app (
- Commit SHA: If you use a version control system like Git, we recommend using the identifying hash (for example, the commit SHA,
da39a3ee5e6b4b0d3255bfef95601890afd80709). You can let Sentry CLI automatically determine this hash for supported version control systems. Learn more in our Sentry CLI documentation.
Releases are global per organization; prefix them with something project-specific for easy differentiation.
The behavior of a few features depends on whether a project is using semantic or time-based versioning.
- Regression detection
We automatically detect whether a project is using semantic or time-based versioning based on:
- If ≤ 2 releases total: we look at most recent release.
- If 3-9 releases (inclusive): if any of the most recent 3 releases is semver, project is semver.
- If 10 or more releases: if any of the most recent 3 releases is semver, and 3 out of the most recent 10 releases is semver, then the project is semver.
#include <sentry.h> sentry_options_t *options = sentry_options_new(); sentry_options_set_release(options, "email@example.com"); sentry_init(options);
How you make the release name (or version) available to your code is up to you. For example, you could use an environment variable that is set during the build process or during initial start-up.
Setting the release name tags each event with that release name. We recommend that you tell Sentry about a new release before sending events with that release name, as this will unlock a few more features. Learn more in our Releases documentation.
If you don't tell Sentry about a new release, Sentry will automatically create a release entity in the system the first time it sees an event with that release ID.
After configuring your SDK, you can install a repository integration or manually supply Sentry with your own commit metadata. Read our documentation about setting up releases for further information about integrations, associating commits, and telling Sentry when deploying releases.
Monitor the health of releases by observing user adoption, usage of the application, percentage of crashes, and session data. Release health will provide insight into the impact of crashes and bugs as it relates to user experience, and reveal trends with each new issue through the Release Details graphs and filters.
In order to monitor release health, the SDK sends session data.
A session represents the interaction between the user and the application. Sessions contain a timestamp, a status (if the session was OK or if it crashed), and are always linked to a release. Most Sentry SDKs can manage sessions automatically.
To benefit from the health data, you must use at least version 0.4.0 of the Native SDK.
Release health is captured, by default, unless you specifically disabled collecting it in the initialization options for the SDK.
The SDK automatically starts a new session when it is initialized via
sentry_init, and will end that session automatically when the SDK is shut down via
sentry_close, or explicitly by calling
The SDK currently tracks only one concurrent session and will end the running session when using
sentry_start_session. If you prefer to start sessions manually, consider disabling automatic session tracking during initialization:
sentry_options_t *options = sentry_options_new(); sentry_options_set_release(options, "firstname.lastname@example.org"); sentry_options_set_auto_session_tracking(options, 0); sentry_init(options); // ... sentry_start_session(); // Operations covered by the session go here. sentry_end_session();
