Default States of Monitoring

The default status of monitoring in the Sun N1 System Manager for discovered servers and initialized operating systems is as follows:

Default status of hardware monitoring

When a managed server or other hardware is discovered, monitoring of the managed server or other hardware is enabled by default. Before a manageable server can be monitored, however, it must be discovered and correctly registered with the N1 System Manager. This process is described in Chapter 4, Discovering Manageable Servers. The monitoring of hardware sensors is enabled by default for all managed servers. If a server is deleted and then rediscovered, all states related to that managed server for the purposes of monitoring are lost, regardless of whether monitoring was enabled or disabled for that server when the server was deleted. When the managed server is rediscovered, monitoring is set to true by default. This is true only for servers that were discovered by SP-based discovery.

Default status of OS health monitoring

Disabled by default. When an OS has been successfully provisioned on a managed server and the N1 System Manager management features are supported by using the add server feature command with the agentip specified, OS health monitoring is enabled. The OS provisioning can be performed either through the N1 System Manager or by an external OS installation.

If you are not interested in the values of some OS health attributes, you can disable the threshold severity for the monitoring of those attributes, while continuing to monitor other OS health attributes. This action prevents annoyance alarms. Example 6–9 shows how to accomplish this task. For general information about threshold values, see Monitoring Threshold Values.

Default status of network reachability monitoring

When the management interface of the managed server is discovered, monitoring of the interface is enabled by default. When the management features are added, monitoring of other interfaces is enabled by default.
