NCP Monitoring

NCP monitoring enables you to do the following:

• View performance information about the NCPs in your network
• Perform diagnostics on selected NCPs

Before you can use the NCP monitor, you must have a system image that defines the resources you want to monitor. You can specify whether performance monitoring is done for each resource defined in the system image.

Performance monitoring uses data sampled at regular intervals. The information retrieved by data sampling is used to do the following:

• Trigger alerts if the monitored performance is outside defined boundaries
• Generate online reports that can be viewed from the NCP monitor

System Images

The system image represents the set of resources you can monitor and control. Each system image has a name and a version number. You can define multiple system images, but one system image only can be active in a region at a time. The system image becomes active when it is loaded. A system image is loaded in one of the following ways:

• At region startup
• By issuing the LOAD command

Your region uses a default system image if no system image is successfully loaded during startup.

During system image load the following occurs:

• Performance monitoring is started for the NCPs defined in the system image.
• The NCPs are defined to the NCP monitor.

NCP Definitions

NCP definitions are qualified by the following:

• The system image name and version
• The NCP name

Work with NCPs

The NCP administration facilities let you do the following:

• Update, copy, and delete the NCPs defined when you implement your region
• Add new resources
• Define which NCPs are monitored
• Set the attributes to monitor for each NCP
• Define the conditions that raise alerts and the actions taken

Monitor Resources in a Multisystem Environment

In a multisystem environment, you can view and perform diagnostics from a single monitor on the resources from the connected systems.

In a multisystem environment, each region must load a different system image. Each NCP's system image name is visible on the NCP monitor. For subordinate regions, the system image name must match the name supplied during the multisystem linking process.
