Shutdown and Draining

The default behavior of most SDKs is to send out events over the network asynchronously in the background. This means that some events might be lost if the application shuts down unexpectedly. The SDKs provide mechanisms to cope with this.

The close method optionally takes a timeout in milliseconds and returns a promise that resolves when all pending events are flushed, or the timeout kicks in.

Note that you can call this method on SIGTERM to gracefully shut down a service or container.

Sentry.close(2000).then(function () {
  process.exit();
});

After a call to close, the current client cannot be used anymore. It's important to only call close immediately before shutting down the application.

Alternatively, the flush method drains the event queue while keeping the client enabled for continued use.
