Alerts CCMS

Definition

The Alert Monitor generates alerts in the monitored systems using threshold values and rules, if the status of the systems 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 some other way, even if you are not currently working in the Alert Monitor.

For the system administrator, an alert is an error report or a service request. You should react to every alert. Use the Alert Browser and the analysis method contained in the Alert Monitor to investigate the alert. If you have solved the problem, or are sure that you can safely ignore it, set the alert to complete. The system then removes this alert from the display and saves it to the alert database.

The alert monitor reports alerts up through 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 this incoming information against alert thresholds. If the incoming data exceeds or violates a threshold, then the alert monitor triggers an alert. The alert monitor generates an alert for every abnormal status and keeps track of every alert until it is set to status complete.

You can also use a heartbeat alert to configure an MTE in such a way that an alert is generated if a data supplier fails to report values (see Triggering a Heartbeat Alert if No Values Are Reported).

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 our extensive experience with SAP production systems.

Monitoring attributes are combined into attribute groups. An attribute group contains the threshold values that have common associated monitoring attributes. In this way, all instance-specific occurrences 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 a system. If you want to change threshold values, you only need to change the value for the corresponding attribute group.

Alert Colors and their Meanings

Color	Meaning
red	Problem or Error
yellow	Warning
green	Everything OK
gray	No information available

By default, no alert is generated in the case of a green message. However, you can activate the generation of “green alerts” for selected nodes (see Working with All-Clears (Green Alerts)).
