 The Sentry Nuxt SDK automatically instruments [storage APIs](https://nuxt.com/docs/4.x/guide/directory-structure/server#server-storage) (also known as KV storage) and common operations.
 
 Keep in mind that only the storage mounts configured under `nitro.storage` in your `nuxt.config.ts` will be instrumented. Storage spans will show up in a similar way to [cache](#cache) spans since they both utilize the same underlying Nitro storage API.

 In case the SDK's [default behavior](../#trace-duration) for the trace duration does not fit your needs, you can manually start a new trace that will no longer be connected to the current (distributed) trace.
 This means that spans or errors collected by the SDK during this new trace will not be connected to spans or errors collected before or after this new trace.
