exstat

Exstat is a command-line utility in Unix-like operating systems that provides a summary of system statistics. It is part of the sysstat package, which is commonly used for system performance monitoring and analysis. The name "exstat" is derived from "extended statistics," reflecting its comprehensive nature.

Exstat offers a range of options to display various system statistics, including CPU usage, memory usage, I/O statistics, and more. It can be used to monitor system performance over time, identify bottlenecks, and diagnose issues. The utility can generate reports in different formats, such as plain text, CSV, or JSON, making it versatile for different use cases.

One of the key features of exstat is its ability to collect and display historical data. This is particularly useful for long-term performance analysis and trend identification. Exstat can be configured to run at regular intervals using cron jobs, allowing for continuous monitoring and data collection.

Exstat is a powerful tool for system administrators and IT professionals who need to monitor and analyze system performance. Its flexibility and comprehensive set of features make it a valuable addition to any system monitoring toolkit. However, it requires some familiarity with command-line interfaces and Unix-like operating systems to fully utilize its capabilities.
