Cisco DNA Center platform: Audit log export via Syslog

This code will query Cisco DNA Center for its audit log every [defined period of time], in order to convert the events to an external program/platform using Syslog.

Technology stack: Python + Docker (optional)
Status: Alpha, designed to prove the ability and openess of Cisco DNA Center.

Use Case Description

Even though Cisco DNA Center is a cutting edge solution, some of our customers are using existing monitoring and SIEM systems that use legacy protocols. In this case - syslog.
As Cisco DNA Center is not designed to export its audit log via syslog - this code bridges that gap, allowing the customer to leverage existing syslog-based solution.

Disclaimer

This solution is NOT using DNACaaP APIs, but private APIs. They might stop working in future releases.

How to setup

docker run -d obrigg/cisco-dnac-platform-syslog-audit --dnac_ip 'DNAC-IP' --syslog_ip 'SYSLOG-SERVER-IP' --password 'password'
