Offline Mode

Offline Mode extracts data from your MSM server and saves it to compressed files on your computer.

You can upload these files later when you have a better connection.

When to Use Offline Mode

Use Offline Mode when:

• ✅ You have an unstable internet connection
• ✅ You want to extract data now and upload later

How Offline Mode Works

1. Connects to your MSM server via SSH
2. Extracts telemetry data from the database
3. Saves data to compressed CSV files on your computer
4. Upload files later using Offline Upload Mode

Using Offline Mode

Step 1: Select Offline Mode

In the application interface, select "Offline Mode" from the mode selection.

Step 2: Set Date Range

Configure the extraction period:

1. Start Date & Time: The beginning of your data range
2. End Date & Time: The end of your data range
3. Force re-extract existing partitions: To re-extract already extracted partitions, as the Data Collector keeps track of all extracted partitions and will not re-extract an already extracted partition, unless this is checked.

Force Re-extract

Only enable this option if you need to re-extract data for dates you've already processed. This will overwrite existing files.

Step 3: Configuration

Offline Mode uses the same configuration as Online Mode. You need to configure:

• SSH Configuration: Connection details to your MSM server
• Database Configuration: Database settings
• Validation: Test your configuration before extraction

See the Online Mode Configuration Guide for detailed instructions on:

• SSH connection setup
• Database configuration
• Validation process

Step 4: Start Extraction

1. Click the "Start Offline Extraction" button
2. Monitor the progress

Step 5: Monitor Progress

The interface displays:

• Records Processed: Total records extracted
• Files Created: Number of CSV files saved
• Storage Used: Disk space consumed
• Current Status: Active extraction information

Storage Location

All extracted files are saved to:

offline_extractions/
├── extraction_20240101_120000_part_001.csv.gz
├── extraction_20240101_120000_part_002.csv.gz
└── ...

Disk Space

Monitor available disk space. As a rule of thumb, expect ~3 MB per day per SSC on the MSM.

Next Steps

When you're ready to upload:

1. Ensure you have a stable internet connection
2. Use Upload Mode to upload your files
3. Keep the files until upload is confirmed successful

Advantages of Offline Mode

✅ Resilient: Network issues don't interrupt data extraction

✅ Backup: You have local copies of your data

✅ Flexible: Upload when convenient

✅ Reliable: Less chance of data loss

Disadvantages of Offline Mode

❌ Two-step process: Extract then upload separately

❌ Storage required: Need local disk space

❌ Delayed availability: Data not immediately available in cloud
