Working with All-Clears (Green Alerts)
When monitoring a system landscape using a central monitoring system (CEN), the Alert Monitor displays yellow or red alerts in the case of error situations. The monitoring can react to alerts of this type using auto-reaction methods, such as sending corresponding messages to the system administrator as e-mail or SMS.
It is also possible to generate messages for green "alerts" and react to them correspondingly. Green alerts of this type do not indicate error situations, but are intended as all-clears or explicit messages that an action was successful.
- The dialog response time was above the threshold value and therefore created red alerts. The measurements then reduce to a level below the permissible threshold value again. The system is to generate a green alert when the measured value falls below this threshold value.
- The database backup was successful. The system is to explicitly generate a green alert for this message.
Conditions for Triggering Green Alerts
You can activate green alerts in the Alert Monitor for performance attributes and status attributes.
- Behavior in the case of performance attributes
- A green alert is generated if the current status is yellow or red and the next report sets the current status to green
- Nogreen alert is generated if the current status is already green.
- Behavior in the case of status attributes
- A green alert is generated if the current status is yellow or red and the next report sets the current status to green
- A green alert is generated if the current status is white or inactive and the next report sets the current status to green
- Nogreen alert is generated if the current status is already green.
To be able to generate green alerts, set the profile parameter alert/GREEN_ALERTS=1 (see Profile Maintenance) in all instances profiles in CEN and in the systems in which you want to create green alerts.
After restarting, the monitored systems and CEN can now generate green alerts.
You can also specify the above profile parameter in the Profile File of a Host Agent. In this case, green alerts are generated for the MTEs that are transferred to the CEN using the relevant agent.
To activate green alerts for individual nodes, proceed as follows:
- Start the Alert Monitor in CEN by calling transaction RZ20.
- Choose Extras → Activate Maintenance Functions.
- Start the desired monitor and select the desired nodes.
- Choose the Properties button, and Monitoring: Properties and Methods screen, choose the General tab page. You can change the Maximum number of alerts kept here. By default, this value is 10.
- To permit green alerts, enter a negative value here, such as -10. The negative sign signals to the monitoring architecture that green alerts can be generated for this node. The amount of the number set specifies the total number of alerts that can be generated for the node.Note
Note that when you make this setting, the permitting of green alerts is activated for all nodes with the same MTE class in the system. Alternatively, you can also make the setting for an individual node by first choosing Edit → Properties → Use for individual MTE on the Monitoring: Properties and Methods screen.
- Save your settings.
The monitoring architecture now generates green alerts in accordance with the above conditions for the nodes that you selected. Green alerts are displayed in the Alert Browser and behave in the same way as regular yellow and red alerts.
In particular, green alerts are taken into account by auto-reaction methods and can therefore be used to forward benign system messages and all-clears to the system administrator by mail or SMS (see, for example, Forwarding Alerts to Alert Management (ALM)).
