Microsoft SQL Server is a relational database management system developed by Microsoft. As a database server, it is a software product with the primary function of storing and retrieving data as requested by other software applications which may run either on the same computer or on another computer across a network.
This guide has been written for integration with 32 bit and 64 bit Windows machines.

Integration of Microsoft SQL Logs via NXLog with DNIF

To configure NXLog to send Microsoft SQL logs to DNIF Adapter.

If you want to integrate Apache WAMP access logs as well as Windows event logs, please refer our help guide: Integrating Windows Event Logs.

Download and Install Nxlog

Download and install the latest version of NXLog on the Windows machine from which the logs need to be collected.
After installation, locate the nxlog.conf file in the C:\Program Files (x86)\nxlog\conf folder.
In 32 bit Windows machines, look in the C:\Program Files\nxlog\conf folder,
