Event logs, security logs, transactions, web server uptime, and CDN traffic are just a few of the types of logs you will collect.

Why do i need a web server log analyzer?

So why do you need a web server log analyzer? All of this data can quickly become overwhelming. To maximize data usage, you need to be able to easily find and analyze log files from a central location. Web log analysis tools allow you to filter logs, perform real-time searches, and query specific log data. These tools also present this data in a centralized view accessible from anywhere.

This can mean creating policies on how you generate and store logs or automating when logs are archived after a certain amount of time.
