# File Monitor Input Adapter Sample

## About This Sample

This adapter sample illustrates the use of the TIBCO StreamBase® File Monitor Adapter, which watches a directory or specific file for changes and emits tuples that describe file system changes as they occur.

## Importing This Sample into StreamBase Studio

In StreamBase Studio, import this sample with the following steps:

- From the top-level menu, select File → Load StreamBase Sample.

- Enter `filem` to narrow the list of options.

- Select File Monitor input adapter from the StreamBase Standard Adapters category.

- Click OK.

StreamBase Studio creates a single project containing the sample files.

## Running This Sample in StreamBase Studio

1. In the Project Explorer view, open the sample you just loaded.

   If you see red marks on a project folder, wait a moment for the project to load its features.

   If the red marks do not resolve themselves after a minute, select the project, right-click, and select Maven → Update Project from the context menu.

2. Open the `src/main/eventflow/`packageName`` folder.

3. Open the `filemonitor.sbapp` file and click the Run button. This opens the SB Test/Debug perspective and starts the module.

4. By default the file monitor sample is set up to monitor your Java temp directory. If you want to monitor another folder:

   In the Manual Input view, select the Control stream.

   Enter a path for path, and `true` for the remaining fields and click Send Data.

5. In the Output Streams view, observe tuples emitted on the `FileMonitorStatus` output stream

6. Use a command window or file system tool to modify the folders and files inside the TestFolder or add and delete other files and folders. Observe the content of tuples emitted on the `FileNotifications` output stream.

7. Press F9 or click the Terminate EventFlow Fragment button.

## Sample Location

When you load the sample into StreamBase Studio, Studio copies the sample project's files to your Studio workspace, which is normally part of your home directory, with full access rights.
