A log analyzer is a software tool that helps users examine and interpret log files generated by various systems, such as servers, applications, and network devices. These log files contain records of events, transactions, and errors, which can be crucial for troubleshooting issues, monitoring performance, and ensuring security. By parsing and visualizing this data, log analyzers make it easier to identify patterns and anomalies. Many log analyzers offer features like real-time monitoring, alerting, and reporting. Popular examples include Splunk, ELK Stack, and Graylog. These tools are widely used in IT operations, cybersecurity, and compliance to enhance system reliability and performance.
