Support for multiple DSNs in Sentry.init()

[StreethawkNick]

The documentation for the Android configuration doesn't seem to outline how to use multiple DSNs.

    // Use the Sentry DSN (client key) from the Project Settings page on Sentry
    String sentryDsn = "https://publicKey:secretKey@host:port/1?options";
    Sentry.init(sentryDsn, new AndroidSentryClientFactory(ctx));

Diving deeper into the code it shows that storedClient is a static volatile which makes me believe it can't support it.

 public static void setStoredClient(SentryClient client) {
    if (storedClient != null) {
        logger.warn("Overwriting statically stored SentryClient instance {} with {}.", storedClient, client);
    }

    storedClient = client;
}

The reasoning behind wanting multiple DNS is because I'm developing a third party library, so I need Sentry to send events to me, while in the App they also have Sentry to send events to their own.

Is this possible?

You aren't required to use the static Sentry API (which stores and uses the global reference), that should probably be reserved for application owners.

What you can do is create your own SentryClient with SentryClientFactory.sentryClient(dsn) and store the reference somewhere yourself, then use sendEvent, sendMessage, or sendException yourself.

As an aside, I would make it very clear that you are doing this, limit what sort of information you send, and offer a way to disable it. You could send all kinds of user/application state to Sentry from your library and users of the library should know that information could be leaking to you/us.

Wonderful, thanks a million, I will use that approach.

Thanks again for the advice, we will offer a way to disable it. In addition, our exception handling ignores App level exceptions since it detects which package name the exception came from.

FYI: I posted an answer of how to do this in the Python SDK here

Basically, I create my own transport that wraps around multiple transports. In my case, I wanted to have the global handler send to both DSNs.

Hey there! SentryClientFactory seems to no longer exist in recent SDK versions, are multiple DSNs still supported?

[marandaneto]

@carloswabreu1 you can create multiple instances of Hub, the DSN is set to SentryOptions which is a ctor param from Hub

Thanks @marandaneto! I couldn't find documentation about this other than a short summary here, could you share an example or more documentation?
