Microsoft SQL Server Logs
The Microsoft SQL Server error logs includes backup and restore operations, batch commands, or other scripts and processes (see more here). This can be helpful to detect any current or potential problem areas, including automatic recovery messages (particularly if an instance of SQL Server has been stopped and restarted), kernel messages, audit failures like failed logins, or other server-level error messages.
This guide was written for Windows Vista or later in 64-bit, the latest version of nxlog in the default installation directory, SQL Server 2008 R2, and can send TCP events out on port 514. It was tested on Amazon EC2 with Windows_Server-2008-R2_SP1-English-64Bit-SQL_2008_R2_SP2_Express-2013.11.13 (ami-1653c826). For alternatives, please see the Advanced Options section.
- Install Nxlog
Install nxlog using this guide if you haven’t already. SQL Server will send error logs to the Windows Event Log by default, where Nxlog reads them using the im_msvistalog module, and then converts them to JSON so Loggly can parse and index the fields.
