SDKs are configurable using a variety of options. The options are largely standardized among SDKs, but there are some differences to better accommodate platform peculiarities. Options are set when the SDK is first initialized.
Options are passed to the
init() method as an array:
Sentry\init([ 'dsn' => 'https://examplePublicKey@o0.ingest.sentry.io/0', 'max_breadcrumbs' => 50, ]);
Some of the options listed below that are marked as not available may be available in another form; see PHP specific documentation.
The list of common options across SDKs. These work more or less the same in all SDKs, but some subtle differences will exist to better support the platform. Options that can be read from an environment variable or your
~/.sentryclirc file (
SENTRY_RELEASE) are read automatically. See Working with Projects for more information.
The DSN tells the SDK where to send the events. If this value is not provided, the SDK will try to read it from the
SENTRY_DSN environment variable. If that variable also does not exist, the SDK will just not send any events.
In runtimes without a process environment (such as the browser) that fallback does not apply.
Sets the release. Some SDKs will try to automatically configure a release out of the box but it's a better idea to manually set it to guarantee that the release is in sync with your deploy integrations or source map uploads. Release names are strings, but some formats are detected by Sentry and might be rendered differently. Learn more about how to send release data so Sentry can tell you about regressions between releases and identify the potential source in the releases documentation.
By default the SDK will try to read this value from the
SENTRY_RELEASE environment variable (in the browser SDK, this will be read off of the
window.SENTRY_RELEASE if available).
Sets the environment. This string is freeform and not set by default. A release can be associated with more than one environment to separate them in the UI (think
prod or similar).
By default the SDK will try to read this value from the
SENTRY_ENVIRONMENT environment variable (except for the browser SDK where this is not applicable).
Sets which errors are reported. It takes the same values as PHP's
error_reporting configuration parameter.
By default all types of errors are be reported (equivalent to
Configures the sample rate as a percentage of events to be sent in the range of
1.0. The default is
1.0 which means that 100% of events are sent. If set to
0.1 only 10% of events will be sent. Events are picked randomly.
This variable controls the total amount of breadcrumbs that should be captured. This defaults to
When enabled, stack traces are automatically attached to all messages logged. Stack traces are always attached to exceptions; however, when this option is set, stack traces are also sent with messages. This option, for instance, means that stack traces appear next to all log messages.
This option is
off by default.
Grouping in Sentry is different for events with stack traces and without. As a result, you will get new groups as you enable or disable this flag for certain events.
This option can be used to supply a "server name." When provided, the name of the server is sent along and persisted in the event. For many integrations the server name actually corresponds to the device hostname, even in situations where the machine is not actually a server. Most SDKs will attempt to auto-discover this value.
A list of string prefixes of module names that belong to the app. This option takes precedence over
A list of string prefixes of module names that do not belong to the app, but rather to third-party packages. Modules considered not part of the app will be hidden from stack traces by default.
This option can be overridden using
This parameter controls if integrations should capture HTTP request bodies. It can be set to one of the following values:
never: request bodies are never sent
small: only small request bodies will be captured where the cutoff for small depends on the SDK (typically 4KB)
medium: medium and small requests will be captured (typically 10KB)
always: the SDK will always capture the request body for as long as Sentry can make sense of it
These options can be used to hook the SDK in various ways to customize the reporting of events.
This function is called with an SDK-specific event object, and can return a modified event object or nothing to skip reporting the event. This can be used, for instance, for manual PII stripping before sending.
This function is called with an SDK-specific breadcrumb object before the breadcrumb is added to the scope. When nothing is returned from the function, the breadcrumb is dropped. To pass the breadcrumb through, return the first argument, which contains the breadcrumb object. The callback typically gets a second argument (called a "hint") which contains the original object from which the breadcrumb was created to further customize what the breadcrumb should look like.
Transports are used to send events to Sentry. Transports can be customized to some degree to better support highly specific deployments.
Switches out the transport used to send events. How this works depends on the SDK. It can, for instance, be used to capture events for unit-testing or to send it through some more complex setup that requires proxy authentication.
When set, a proxy can be configured that should be used for outbound requests. This is also used for HTTPS requests unless a separate
https-proxy is configured. However, not all SDKs support a separate HTTPS proxy. SDKs will attempt to default to the system-wide configured proxy, if possible. For instance, on Unix systems, the
http_proxy environment variable will be picked up.
