You can receive notification when the actual performance time of a resource exceeds the acceptable threshold that you define for it. These notifications are called alerts. The following kinds of alerts are available:
General alerts track alerts throughout the entire network. General alerts are generated only for the network resources for which you have created monitors.
You specify a monitor defining which resource to monitor for general alerts, the threshold time above which a general alert for that resource is generated, and where to send the alert messages.
The graphic alerts feature indicates when resources in your network exceed specified thresholds and displays current data in bar chart format. Each bar represents a network response variable and is highlighted when the reading for the variable exceeds the specified threshold. You can also configure the feature to make the terminal beep when a threshold is exceeded.
A sample graphic alert screen is shown in the following diagram. It depicts the average host and network response times for various applications compared to the worst host and network response times. It also displays the average user response time and the number of sessions for each application.

The graphic alerts function receives its data from the regular network monitoring functions (VTAM and NCP statistics) and operates independently from the tracing facilities. You can set up the feature to report on six resource types per screen and receive up to 48 graphs. Resource types include applications, lines, LUs (terminals), NCPs, PUs (clusters), and VRs (virtual routes).
You can use graphic alerts to compare data from several different resources simultaneously on one screen. For example, you can select four resources to be graphed, with one variable each. The screen is automatically divided into four sections with a graph in each section.
Trace alerts notify you when the network, host, or user response time has exceeded the threshold that you have specified. When a trace alert is generated, an exception trace entry is created. You can display trace alert statistics online.
