Configure
As of now, the main solution to collect ISC DHCP logs leverages the Rsyslog recipe. Please share your experiences with other recipes by editing this documentation.
Rsyslog
Please refer to the documentation of ISC DHPD to forward events to your rsyslog server. The reader can consult the Rsyslog Transport documentation to forward these logs to SEKOIA.IO.
