NXLog Installation

NXLog for log collection Direct link to this section

NXLog is a third-party tool that collects and processes logs. Arctic Wolf® uses NXLog to package the following log files into Snare files that are generated by the Windows Server domain controller directory service:

The Snare files are sent to the Arctic Wolf syslog listener, located on an Arctic Wolf Sensor or Virtual Log Collector (vLC), where they are preprocessed and then sent to the Arctic Wolf platform.
