Managing Default Threshold Values (Sun N1 System Manager 1.2 Administration Guide)

Sun N1 System Manager 1.2 Administration Guide

Managing Default Threshold Values

Factory-configured default threshold values are provided in the N1 System Manager software for some OS health thresholds. These values are stated as percentages. Table 5–1 lists default values for these OS health attributes for a Sun Fire V20z server.

Note –

Setting or modifying threshold values for hardware health attributes is not supported in this version of the Sun N1 System Manager.

Specific threshold values can be set at the command line by following the procedures described in Setting Threshold Values.

Table 5–2 provides the complete list of OS health attributes.
