# View workflow logs
tail -f /var/log/lambdasoftworks/workflows/daily_backup.log

Troubleshooting

Common Issues

1. Workflow Execution Issues

   • Check workflow definition syntax
   • Verify command paths
   • Review timeout settings
   • Check dependencies

2. Scheduling Issues

   • Verify cron syntax
   • Check system time
   • Review schedule conflicts
   • Check system resources

3. Reporting Issues

   • Check log directory permissions
   • Verify report template access
   • Check disk space
