5 Best Log Analyzer Tools for IIS Web Servers

By SolarWinds on February 5, 2021


What Is an IIS Web Server?

An Internet Information Services (IIS) web server is a secure and advanced web server running on the Windows operating system. It’s used for hosting websites, applications, and services and sharing information with users over the internet or intranet.

IIS web servers generate a massive amount of raw and unfiltered logs every day. The logs provide valuable insights into user behavior, the operational status of websites, usage, and security elements development teams use to troubleshoot errors, performance issues, and server availability issues. To help streamline the process of reviewing IIS logs, IT organizations deploy advanced and reliable log analysis tools.

What Information Do IIS Logs Provide?

IIS logs provide performance, operational, security, and business insights. With the help of these insights, development teams analyze various aspects of server and user activities, such as the time taken to complete a request, the total volume of data sent or received by the server, the HTTP status code to determine server response, and user behavior on a website. 

Outlined below are the best log analysis tools to help teams quickly identify and resolve issues:
