Chapter 4 Polling and Emailing

Setting Threshold Alarms

You can generate a Threshold Alarm when a polled SNMP variable value meets certain criteria.

ProSafe NMS supports three distinct mechanisms for generating Threshold Alarms as described in

the following table.

Table 4-1. Threshold Alarms

Alarm Type Description

Status Variable Polling Use the Object Properties dialog to set a single SNMP

variable plus instance that is polled in real time (Poll Interval

attribute seconds). Use this for Emergency Status Polling. For

example, poll for UPS battery failure, disk full, or link down

conditions.

Automatic Trend Baseline ProSafe NMS automatically determines a baseline value for

all variables in any trend reports that you add. The baseline is

set after a learning period and periodically adjusted. The

polling agent will generate alarms if a polled value exceeds

the baseline by a preset percentage.

Manual Trend Threshold Use manual threshold alarms in trend reports to specify a

particular condition to test. This is commonly used to monitor

line utilization variables. In this case the alarm condition is well

known to the user and involves a longer polling period (for

example, 80% over 10 minutes).
