MongoDB Database Log Forwarding to SIEM

Hi Community,
For PCI Compliance we wanted to integrate the database logs to SIEM, using Mongo Logs API . I done writing python scripts to pull the activity feeds logs for all project & organisation recurringly , but it collects only the audit logs, Management needs the complete Database logs, please suggest the best practise for integrating logs for PCI compliance and suggest the method for log collection.

thanks,
