Configuring IP Node Monitoring › Alert Conditions

Alert Conditions

An alert is a notification of a fault, which you can view on the alert monitor. You can define the alert conditions on IP nodes through an IP node monitor group. Alert conditions are set separately for each IP node monitor group; therefore, the same attribute can have different alert conditions in different groups.

Numeric attributes, such as PINGRTT, have the following alert conditions:

• Above and below a threshold (absolute value)
• Above and below a baseline (moving average)

Note: Because IP nodes are sampled regularly and often at short intervals, HourOfDay is usually a suitable baseline type for IP nodes.

Each single alert condition can raise one of five different alerts. These alerts are of varying severity and text, which is based on the threshold value or baseline percentage. For example, when PINGRTT of a node in the FTPSERVERS group is greater than 5000, you raise a severity 1 alert with the text:

This node is extremely slow.

Also, when PINGRTT of a node in the FTPSERVERS group is greater than 100, you raise a severity 4 alert with the text:

This node is slightly slow.

You can also suppress alerting when an alert condition is satisfied. This feature enables you to trigger actions without sending an alert. To suppress alerting, specify 0 for the alert severity.
