Logs are a powerful source of information, as it contains records of every action that’s done on your network. In fact, when used well, logs can provide rich insights into your network performance, usage and management. In addition, this analysis is sure to help you make the right decisions in important areas like security.
That said, it’s not easy to read logs as they come from different devices in different formats. Reading through this information to identify and solve problems can take days, during which time, the vulnerabilities in your network continue to go undetected. Also, such manual analysis opens the room for misinterpretations and mishandling.
To avoid these problems, event log analysis software is essential. These specialized tools collect information from different devices and analyze the same to give you meaningful insights and actionable data. As a bonus, it makes IT administrators more efficient and productive as they can focus on the output data instead of sifting through mounds of raw and unreadable log data.
Now that we understand the importance of log analysis software. Let’s review the best ones in the market today.
