SplunkFlow

A Python-based intelligent log processing tool that automatically detects log types, extracts structured fields, sends data to Splunk, and generates custom dashboards based on detected log patterns.

🎯 Project Overview

This tool revolutionizes log analysis by combining pattern recognition with automated Splunk integration. It intelligently identifies various log formats (firewall, DNS, Apache, syslog, JSON) and creates tailored visualizations without manual configuration.

πŸ”§ Key Features

  • πŸ” Intelligent Log Detection: Automatically identifies log types using regex pattern matching
  • πŸ“Š Multi-Format Support: Handles firewall, DNS, Apache, syslog, and JSON logs
  • πŸš€ Splunk Integration: Seamless connection and data ingestion to Splunk
  • πŸ“ˆ Auto-Dashboard Generation: Creates custom XML dashboards based on detected log type
  • ⚑ High Performance: Efficient field extraction with detailed success metrics
  • πŸ›‘οΈ Robust Error Handling: Comprehensive error reporting and debugging information

🧩 Core Components

1. Log Processor (log_processor_py.py)

  • Pattern Detection: Uses regex patterns to identify log types
  • Field Extraction: Extracts structured data from unstructured logs
  • Supported Log Types:
    • Firewall (Custom): 2025-08-22 09:15:23 [ALLOW] TCP 192.168.1.45:3421 -> 203.0.113.15:80
    • DNS: client 192.168.1.55#12345: query: google.com IN A
    • Standard Firewall: action=allow src=192.168.1.10 dst=8.8.8.8
    • Apache: 192.168.1.101 - - [19/Jan/2025:10:30:01 +0000] "GET /index.html"
    • Syslog: Jan 19 10:15:32 localhost sshd[1024]: message
    • JSON: Any valid JSON formatted logs

2. Splunk Connector (splunk_connection_py.py)

  • Authentication: Secure connection to Splunk instances
  • Event Ingestion: Bulk upload of processed log events
  • Dynamic Sourcetype: Automatically sets sourcetype based on detected log type

3. Dashboard Generator (main.py)

  • Custom XML Generation: Creates tailored dashboards for each log type
  • Log-Specific Visualizations:
    • Firewall: Top IPs, protocols, blocked traffic trends
    • Apache: URL analysis, status code distribution
    • DNS: Domain queries, query type breakdown
    • Syslog: Process analysis, message patterns

  3. Import Dashboard

    • Click "New Dashboard" or "Create New Dashboard"
    • Select "Dashboard Studio" or "Classic Dashboards"
    • Choose "Upload Dashboard" or "Import from XML"
  4. Upload XML File

    • Browse and select your generated_dashboard.xml file
    • Click "Upload" or "Import"
  5. Verify Dashboard

    • The dashboard will appear in your dashboards list
    • Click on it to view your auto-generated visualizations

Method 2: Manual XML Import

  1. Open the generated XML file in a text editor
  2. Copy the entire XML content
  3. In Splunk Web, go to Settings > User Interface > Views
  4. Click "New View"
  5. Paste the XML content in the source editor
  6. Save the dashboard

  • Check Splunk permissions for dashboard creation
  • Verify compatible Splunk version (dashboard format)

Search Query Issues:

  • Confirm field names match extracted data
  • Test individual search queries in Splunk's Search app
  • Check for case sensitivity in field values

πŸ”§ Advanced Features

Custom Log Patterns

Add new log types by extending the log_patterns dictionary in LogProcessor:

'custom_type': {
    'pattern': r'your_regex_pattern_here',
    'fields': ['field1', 'field2', 'field3'],
    'description': 'Description of your custom log type'
}

Dashboard Customization

The dashboard generator creates type-specific visualizations. You can extend generate_dashboard_xml() for custom chart types.
