If you need to monitor, analyze and improve performance for physical and virtual operating systems, servers, and storage devices within a data center, rather than just monitoring performance within individual systems, you can use the comprehensive system management solutions available in the Oracle Enterprise Manager Ops Center.
The monitoring feature in the Enterprise Manager Ops Center provides extensive information about the monitored operating systems and zones in your data center. You can use the information to evaluate performance, identify issues, and perform tuning. Analytics are available for the Oracle Solaris operating system, for Linux, and for OS virtualization technologies including Oracle Solaris Zones, Oracle VM Server for SPARC, and Oracle VM Server for x86 guests.
