reqvis will support standard Apache log formats including:

• Common Log Format (CLF)
• Combined Log Format
• Custom log formats (documentation coming soon)

To prepare your log files for visualization with reqvis:

1. Access your Apache server logs (typically found in /var/log/apache2/ or /var/log/httpd/)
2. For large log files, consider extracting a relevant portion:

# Extract the last 1000 lines from access.log
tail -n 1000 /var/log/apache2/access.log > sample_logs.log

# Extract logs from a specific date range
grep "25/Apr/2025" /var/log/apache2/access.log > sample_logs.log

3. Remove any sensitive information if needed before uploading

To exclude requests to admin paths (e.g., URLs containing /admin), you can use grep -v:

grep "25/Apr/2025" /var/log/apache2/access.log | grep -v "/admin" > sample_logs.log
