Table of contents
Download the installation package from the NXLog website, or a copy from our AWS repository:
Open the installer and following the on screen instructions to install NXLog.
After installation, a README for NXLog should appear. (It is also copied below.)
README Please edit the configuration file after installation. This should be located under C:\Program Files\nxlog\conf\nxlog.conf or C:\Program Files (x86)\nxlog\conf\nxlog.conf depending on your windows architecture. You might need to adjust the ROOT folder in the config file, otherwise nxlog will not start. After this is done, you should be able to start the nxlog service from the service manager. Alternatively, the service can be also started by executing C:\Program Files (x86)\nxlog\nxlog.exe. Running the executable with the -f command line argument will run it in foreground if you don't want to run it as a service. nxlog will write its own messages to the logfile located under C:\Program Files (x86)\nxlog\data\nxlog.log If you have trouble starting or running it, please take a look there. See the NXLOG Reference Manual for details about configuration and usage. The manual should be available online at http://nxlog.org/resources and is also installed under C:\Program Files (x86)\nxlog\doc\
Note: We can provided several .conf files (dependent on Windows Server OS version) already configured for the deployed Fluency instance. Additional editing should not be needed. It will replace the original .conf file from the installation.
The provided nxlog.conf file should be placed under:
C:\Program Files (x86)\nxlog\conf\nxlog.conf
Under Start Menu, choose Administrative Tools, then select Services to open the Services Configuration Window
Find and right-click the “nxlog” item, and choose the desired operation. (Start/Stop/Restart)
Under Start Menu, choose Administrative Tools, then select DHCP to open the DHCP Configuration Window
Under IPv4 (right-click), select Properties
Verify that the “Enable DHCP audit logging” option is enabled. Click OK to confirm/exit.

Replace the “Output fluency_out” section in the default nxlog.conf file with the above text.
NOTE: An additional root certificate (ca.crt) will also be needed. This certificate file should be placed in the same directory as the nxlog.conf file on the target Windows server/machine. Please contact Fluency Support if you were not provided with this file.
