snapshot.py is a Python script designed to retrieve information about snapshots from a storage system using its API. It authenticates with the API using provided credentials, retrieves information about snapshots for a specified volume, and saves the snapshot data to JSON and CSV files.

python snapshot.py <storage> <svm> <volume>

• <storage>: Name of the storage system.
• <svm>: Name of the Storage Virtual Machine (SVM).
• <volume>: Name of the volume.

• base64
• requests
• json
• pandas
• dateutil.parser

• Functionality
• conv_time(time):

1. conv_time(time):

   • Converts the snapshot creation time from ISO 8601 format to a formatted string.

2. get_headers(username, password):

   • Generates authentication headers for API requests.

3. get_snapshots(storage, svm, volume, headers):

   • Retrieves information about snapshots for a specified volume.

4. get_snapshot_data(storage, uuid, headers):

   • Retrieves detailed information about each snapshot, including reclaimable space.

5. get_volume_uuid(storage, svm, volume, headers):

   • Retrieves the UUID of a volume.

6. save_to_json(data, filename):

   • Saves JSON data to a file.

7. save_to_csv(data, filename):

   • Saves JSON data to a CSV file.

8. main(args):

   • Main function to execute the program. Parses command-line arguments, retrieves snapshot data, and saves it to JSON and CSV files.

This command retrieves snapshot data for the volume "volume1" in the SVM "svm1" of the storage system "storage1", and saves the data to JSON and CSV files.

Note: Ensure to replace "storage1", "svm1", and "volume1" with the actual names of your storage system, SVM, and volume, respectively.
