1 Requirements
2 NxLog Configuration
3 Enabling Audit Logs
4 Verification
5 Using UI

This article explains the steps to configure logs from IIS application, MS SQL application and Windows OS Audit-Logs from the same machine.

Requirements

Admin access to the window machine running all these applications.
Admin access to the MS SQL applications.
Port - UDP 514 and 5154 allowed from the windows machine running all the applications , outwards to the CCE.

NxLog Configuration

Login on collector/AD computer.
Download the latest version of nxlog. It is easiest to choose the Windows msi file which includes an installer. Use the link : http://nxlog.org/products/nxlog-community-edition/download
Open the Nxlog configuration file at: C:\Program Files (x86)\nxlog\conf\nxlog.conf
Replace the entire configuration file by pasting the following Below – Note to replace the variable (IP Address of Seceon Collector) with the actual Seceon Server IP address:

## This is a sample configuration file. See the nxlog reference manual about the
## configuration options. It should be installed locally and is also available
## online at http://nxlog.org/docs/
## Please set the ROOT to the folder your nxlog was installed into,
## otherwise it will not start.
#define ROOT C:\Program Files\nxlog

define ROOT C:\Program Files (x86)\nxlog
define ROOT C:\Program Files (x86)\nxlog

Moduledir %ROOT%\modules
CacheDir %ROOT%\data
