Definition

A monitoring object represents a component of the IT environment that is to be monitored, such as the CPU of a server, the dialog system, or background processing. Monitoring attributes are values, statuses, or texts that are reported to this object, such as the CPU utilization, or the average response time in the dialog system. A monitoring attribute can be assigned an alert. The selection of the monitoring objects is performed using the data suppliers that exist for all areas of system management.

Structure

Monitoring objects and their attributes are displayed in the alert monitoring tree as individual nodes in a hierarchical tree. If the data reported to the monitoring architecture exceeds or falls below the defined alert threshold values, an alert is triggered in the corresponding monitoring tree element.

There are five different types of monitoring attributes:

You can assign methods to monitoring attributes. A method can be a report, a function module, an SAP transaction, or a URL that is to executed as a reaction to an alert. You can execute these methods within the Alert Monitor. If you double click, for example, the MTE for prematurely terminated jobs, the monitoring architecture automatically starts the job management transaction, in which the job reported in the MTE is already selected.

Use

Performance attributes (symbol ) are monitoring attributes that collect certain reported performance data and calculate the average.

Features

In the display of the properties and methods, performance attributes have a number of special characteristics that are described here. To display the properties of a performance attribute, choose the attribute in the alert monitoring tree and choose Properties.

Comparison Value

Threshold values

In this group box, you can edit the threshold values with which an alert is triggered if the reported value exceeds or falls below the appropriate value. Note when doing so that the change applies not only to the concrete monitoring tree element (MTE), but for the whole MTE class. This is displayed at the top of the screen.

You have the option to assign different threshold values for a Change from GREEN to YELLOW and the Reset from YELLOW to GREEN (the same also applies for the Change from YELLOW to RED and the Reset from RED to YELLOW). This prevents a constant switching between the alert levels, if the attribute is wavering around the threshold value, which would generate a new alert every time.

The display of a rule of this type would look as shown in the graphic below. To find out the alert level, start from any value for the performance attribute and move upwards until you meet the curve. If the value is climbing from a lower alert level, the lower part of the curve is valid for determining the alert; if the value is falling from a higher alert level, the upper part of the curve is used.

The unit of the threshold value is determined using the data supplier.

Explanation for an Alert

If an alert is triggered, it is displayed in the Alert Browser. A short explanatory text for the alert is displayed there in the Alert Text column. Choose the relevant line of an alert and choose F1 to display a more detailed text about the alert. The system displays its short text and the associated message class and number here. You can use these to adjust the delivered message texts.
