libkstat
Libkstat is a software library designed for the Solaris operating system, primarily used to access and manipulate system statistics and kernel metrics. Developed by Sun Microsystems (now Oracle Corporation), libkstat provides a standardized interface for querying kernel statistics related to system performance, hardware, and network interfaces.
The library allows applications to retrieve real-time data on various system components including CPU utilization, memory
Libkstat operates as a user-space library that interacts with kernel drivers to access the kernel statistics
While primarily associated with Solaris, libkstat is integral to the Solaris process management and performance troubleshooting.
In summary, libkstat is a key component for system administrators and developers needing detailed kernel statistics
