Describe the bug
Current state:

• The documentation states a key of isc_dhcp while in fact you need to use isc_dhcpd with the current parser
• It seems this has a history:
• • Typo in Under Known Vendors - ISC - dhcpd key #1769
• • Why was the sourcetype changed on the isc dhcpd sourcetype?? #2003
• I assume something went wrong at a certain point of time.
