422A/0697ECG WHITE PAPER (cont.) ... When an alert occurs while you are not in the Alert view, an alert icon appears in the status bar showing the number of alerts that have occurred since you were last in the Alert view (see Figure 5). Date Time Actual Value Trigger value Counter Figure 5: Alert Window A threshold value must be supplied for each counter you want an alert on. For power supply management purposes, alerts can be set to monitor the % (voltage (V)) channel power capacity performance counter. This will allow you to be alerted before the power supply subsystem is no longer redundant. If the % (voltage (V)) channel power capacity value exceeds 50%, the power supply subsystem is not redundant. For example: if the %5V channel power capacity is greater than 50 then the system is not redundant; if it is less than 50, the system is redundant. Therefore, if you set the alert threshold value over 45%, you will receive notification before the system is no longer redundant. Figure 5 shows a threshold (trigger) value of 45% for the %12V channel power capacity, %5V channel power capacity, %3V channel power capacity, and the % Power capacity performance counters. On 5/22/97 at 8:09 a.m. the %5V channel power capacity exceeded 45%, the data value that was read was 77%. The alert interval is set to the default value of 5 seconds. The specified counters will be checked for the alert condition every 5 seconds. 16
