Overview
NXLOG is used to process the collected information and send it on from Windows event logs and forward these logs to the OTM CCE.
NXLog uses Apache-style configuration files. The configuration file is loaded from its default location, or it can be explicitly specified with the -c command-line argument.
The NXLog configuration file is comprised of blocks and directives. Blocks are similar to XML tags containing multiple directives. Directive names are not case-sensitive but arguments sometimes are.
