# EW SDK Manual Log Retrieval

<Note>
  For Fireblocks' recommended embedded wallet solution, see [Dynamic Embedded Wallets](/docs/dynamic-embedded-wallets). The documentation below covers the legacy Embedded Wallet APIs and SDKs.
</Note>

# Overview

If you experience issues during your application's development phase or with end users, you may need to retrieve EW SDK logs to troubleshoot those issues. To facilitate this, the EW SDK exposes methods that enable you to fetch logs. You can then send the collected logs to your designated servers.

* For our mobile SDKs, a designated interface guides you to a zipped file that you can retrieve from your end-user clients and then upload to your servers.
* The web SDK offers an interface that lets you write and fetch logs. Refer to the web demo for an example of writing logs to your browser's indexed database.

# Example

<CodeGroup>
  ```bash bash theme={"system"}
  // First you need to initialize the NCW SDK with an implementation of the looger 
  const logger: IndexedDBLogger = await IndexedDBLoggerFactory({ deviceId, logger: ConsoleLoggerFactory() });

  const fireblocksNCW = await FireblocksNCWFactory({
            env: ENV_CONFIG.NCW_SDK_ENV,
            logLevel: "INFO",
            deviceId,
            messagesHandler,
            eventsHandler,
            secureStorageProvider,
            logger,
          });

  // Number of logs collected
  const numberOfLogs = await logger.count();

  // Collect 10 logs 
  const logs = await logger.collect(10);

  // Clears the oldest 10 logs
  await logger.clear(10);
  ```

  ```bash bash theme={"system"}
  guard let url = FireblocksManager.shared.getSdkInstance()?.getURLForLogFiles() else {
              print("Can't get file log url")
              return
  }
  ```

  ```bash bash theme={"system"}

  val sdkUri = Fireblocks.getUriForLogFiles(context)
  ```
