The SAP Systems Manager snap-in for the MMC provides essential information for monitoring the SAP system and offers functions to start, stop and restart the system. All the information and functions available for the SAP system can be accessed in the same way as the functions of other tools incorporated in the MMC. Therefore, before you begin working with the SAP snap-in, it is useful to gain a general overview of the MMC layout and standard methods of accessing information and functions.
The MMC presents information on two panes of a window. The pane on the left is the scope pane. It displays available information in a tree structure that can be expanded and compressed. The pane on the right is the result pane. It shows detailed information about any item selected in the scope pane.
Features
When the MMC has been started, you can display the SAP Systems Manager snap-in by expanding the Console Root. The snap-in consists of a root node, SAP Systems, under which various SAP systems are listed. Under each of these systems, you can display individual instances. Each of the listed instances allows you to navigate to sub-nodes that provide detailed information about the system. The sub-nodes Process List, Current State and Open Alerts are always displayed. The additional nodes, Syslog, Queue Statistic and WP Table, are only available in Expert user mode.
The system icons and the nodes for instances, processes and alerts are displayed in different colors, depending on their state. The colors mean the following:
Gray: Unknown state, only outdated values, system is offline
Green: Error-free
Yellow: Critical
Red: Error
The SAP snap-in periodically updates Process List information at a set time interval. Only the most critical state is passed on from the Process List to the parent instance node above it. The nodes at the SAP system level contain all the states of the instance nodes. For example, if two instances are green, one is red and three are gray, the system node displays all three colors and thus reflects the states of all the instances.
To access detailed information about your SAP system, you have to fully expand one of the SAP instances listed in the MMC scope pane and then select an available item, for example, Open Alerts. Once an item has been selected, the corresponding information is displayed on the result pane. Usually you can navigate from here to further levels of detail or other categories of system information. The following table summarizes the available options:
| Selected Item | Information Displayed |
| SAP Management Domain, | Node for SAP systems or sub Management Domains. The colors indicate states that are automatically refreshed and derived from the subnodes. The node is only available in Active Directory / LDAP mode. |
| SAP system, | The colors inidicate states that are derived from the SAP instance and ITS instance subnodes and are automatically refreshed. If all SAP instances are stopped (gray color), the color of the ITS instance sub-nodes is ignored. |
| Database of an SAP system, | Node for the database of an SAP system. Menu entries and subnodes depend on the database and are implemented in separate database extension snap-ins. |
| SAP Instance, | Node for an SAP instance. The color indicates the state that is automatically refreshed and inherited from the Process List subnode |
| Process List | Displays the processes that were started by the start service and their state. The color is automatically refreshed and reflects the worst state of all started processes. |
| Current Status | Displays detailed information on the current state of the system like transaction RZ20. It allows you to navigate to different categories of system information and levels of detail. You can specify a filter to limit the view to certain subnodes. You have to refresh the information manually. |
| Open Alerts | Displays the most serious alerts in the system like transaction RZ20. You can specify a filter to limit the view to certain subnodes. You have to refresh the information manually. |
| Syslog | Displays the system log, even if the SAP system is not functioning properly or is offline. You have to refresh the information manually.It is only available in expert mode. |
| Queue Statistic | Displays the state of the SAP queues. You have to refresh the information manually. It is only available in expert mode. |
| WP Table | Displays information on work processes like transaction SM50. The SAP system has to be started, but does not have to be functioning properly as shared memory of the SAP system is accessed. You have to refresh the information manually. It is only available in expert mode. |
| Process Table | Displays information on J2EE processes. The J2EE engine has to be started, but does not have to be functioning properly as shared memory of the J2EE engine is accessed . You have to refresh the information manually. It is only available in expert mode. |
| ITS Instance, | Displays the internet addresses handled by the ITS instance and their states. The color is automatically refreshed and summarizes the internet addresses' states. If some internet addresses are available and some not, the ITS instance state color is yellow. If all internet addresses are available/fail the ITS instance color is green/red. The node is only available in Active Directory / LDAP mode. |
You can choose to display the information you require in different ways using the View option. For example, the options Large icons, Small icons or List allow you to change the size and format of the display. Note that for the nodes Alerts, Syslog, Queue Statistic, WP Table, only the option List makes sense and is therefore the automatic default setting.
You can update the information displayed at any time using the Refresh option that is available on the context menu.
