Get Started with Monitoring Oracle Operating Systems

The operating system is part of the core platform and its metrics are leveraged across other targets in Enterprise Manager. This chapter only covers Oracle Solaris and Linux monitoring.

To view all the hosts monitored by Oracle Enterprise Manager, select Hosts in the Targets menu of the Enterprise Manager Cloud Control. The Hosts section of the user interface displays Oracle Solaris and Linux operating system configuration, resource and process metrics.

Performance and configuration metrics provide you with a unified view of an operating system's CPU, memory, and process resource usage, enabling you to manage and optimize resources.

Monitoring is activated when you discover and manage the operating system. A series of escalating status levels notifies you when something is not operating as expected. The lowest level incident status is warning, then critical, and the highest level is a fatal incident.

The information on an operating system is designed to help you maximize performance and utilization. The Host Summary provides a high-level overview of the host. You can drill down to view CPU and resource usage and deeper to view the processes that are running on the host, and real time display of current top processes on a host.

The following features are available for operating systems:

• OS details: Displays operating system resource and processes information, Oracle Solaris Zones and boot environments.

• Incidents: Notification of incidents with links to view details. A series of monitoring rules and parameters monitor your managed assets. Events and incidents are raised for resources that are not performing as expected.

• Performance: Analytics: Provides a detailed view into operating system performance and resource usage.

• Configuration: Indicates configuration changes to the operating system.
