Alerts
Definition
Using threshold values and alerts, the
Alert Monitor generates alerts in the monitored systems if their status deviates from the norm. These alerts attract your attention to critical situations so that you do not have to search for them yourself. Auto reaction methods can inform you about a problem, or react to it in another way, even if you are not currently working in the Alert Monitor.For the system administrator, an alert is an error message or a service request. You should react to every alert. Investigate the alert using the
Alert Browser and the analysis methods contained in the Alert Monitor. When you have solved the problem, or are sure that you can ignore it without concern, set the alert to completed. The system then removes this alert from the display and saves it to the alert database.The Alert Monitor reports alerts upwards in the monitoring tree . This means that the color indicator for a node is always the color of the highest alert in all elements of its branch. If, for example, a host system has a red indicator, one or more components in the monitoring tree for the host system are displaying red alerts.
An alert is uniquely assigned to one monitoring tree element (MTE) in the
monitoring tree. The alert is generated when values are sent from a data supplier to an MTE. The Alert Monitor evaluates the incoming information in comparison to the alert threshold values. If the incoming data exceeds or falls below a threshold value, the Alert Monitor triggers an alert. The Alert Monitor creates an alert for every status that deviates from the standard and traces it until it is set to completed status.Alert Threshold Values and Assignment to Attribute Groups
Reliable values for threshold values and the severity of alerts are predefined for all monitoring attributes. These settings are based on SAP’s extensive experience with SAP R/3 production systems.
Monitoring attributes are combined into attribute groups. An attribute groups contains the threshold values that have common associated monitoring attributes. In this way, all instance-specific copies of the Response Time monitoring attribute belong by default to one attribute group. This means that the same threshold values are set for the response time in all instances of an SAP R/3 System. If you want to change threshold values, you only need to change the value for the corresponding attribute group.
