To monitor the configuration infrastructure of AS Java, you can use the following tools:
● Java Configuration Browser – displays all available configuration objects, their hierarchical tree-structure, and content.
● Java System Reports – enables monitoring of the Configuration Manager operations and performance. Additionally, you can use it to reconfigure the thresholds for Configuration Manager system alerts.
● Shell administration commands – commands that allow you to thoroughly monitor the behavior of the AS Java configuration infrastructure. These advanced monitoring tasks can be used to troubleshoot the system in case of problems.
