Log Categories
Application Logs
Contains general application logging information, including startup, shutdown, and general operational messages.
Transaction Logs
Records all transaction-related activities, including executed trades and identified arbitrage opportunities.
Event Logs
Captures DEX event processing, including liquidity events and swap events. These logs are rotated when they reach a certain size.
Archived Logs
Contains compressed historical logs that are retained for a specified period.
Monitoring Logs
Stores periodic metrics and monitoring data.
Log Rotation
Log rotation is managed by the scripts/rotate-logs.sh script, which:
- Compresses event logs when they exceed 100MB
- Moves compressed logs to the archived directory
- Removes archived logs older than 30 days
Log Management Commands
To manually rotate logs:
./scripts/rotate-logs.sh
To view recent application logs:
tail -f logs/app/mev_bot.log
To view recent error logs:
tail -f logs/app/mev_bot_errors.log
To view recent transaction logs:
tail -f logs/transactions/mev_bot_transactions.log
Log Retention Policy
- Event logs: Compressed and archived when exceeding 100MB
- Archived logs: Retained for 30 days
- All other logs: No automatic rotation (managed by application)
Troubleshooting
If you're experiencing issues with log management:
- Check that the
scripts/rotate-logs.shscript has execute permissions - Verify that the log directories exist and have proper write permissions
- Check disk space availability
- Review script output for error messages
