  title: Solaris Zones Monitoring Statistics API
  description: >-
    REST API for retrieving zone resource utilization statistics on Oracle
    Solaris 11.4 systems. Provides access to the libzonestat functionality
    through the RAD REST interface, enabling programmatic retrieval of per-zone
    resource consumption data including physical memory, virtual memory, CPU
    utilization, and network I/O with sorting and filtering capabilities.
