A remote function call (RFC) is the call of a remote-enabled function module (RFM) in a partner system. The caller is the RFC client and the called partner is the RFC server. Information about the server is stored on the client side in table RFCDES. RFC destinations are maintained in transaction SM59. The remote destination can be another application server in the same or a different R/3 System, an R/2 System, or a non-SAP system.
The following technical prerequisites have to be met in order to use the RFC monitoring:
Performance measurements are based on Real-User Monitoring (RUM) which is also a part of Focused Run. When RFC performance monitoring is set up, RUM is automatically configured in the background.
To be able to monitor interfaces of an on-premise system you first have to add it to Interface & Cloud Monitoring and select the monitoring categories you want to monitor for the system.
In the next step, you see all monitoring categories which are available for the system, depending on the system type and the installed software components. Some recommended standard monitoring categories are preselected.
Select the monitoring categories in scope.
The available monitoring categories are:
After selecting your monitoring categories you have to maintain filters to define what exactly you want to monitor. Some monitoring categories come with standard filters that usually just select all items of this monitoring category. Focused Run can handle this high amount of monitoring data, so you can stick to this standard filters. Or you can set up filters of your own. You can create more than one filter for a monitoring category.
Available Filter Options
For RFC Performance Monitoring, you can collect all RFC destinations in the managed system. You can also use the following filter parameters, to restrict the data collection:
For Connection Monitoring (SM59) you have to provide at least the connection type and the connection name:
Connection Monitoring (SM59)
The setup of the filters for the monitoring categories only makes sure that the data is collected, however, alerts are not created automatically. To create alerts and notifications you have to create an alert individually. If you didn't use specific filters in the setup before, but rather opted to collect all data, you have to create filters for the alerts.
In the next sub-step, you have to maintain the filter. The filter values are the same as described above. For some metrics, you have to maintain metric parameters. Find details below in the overview of the available metrics.
In the last sub-step you have to activate the alert:
For single exceptions, the threshold type is always 'Already Rated'. This means depending on the calculation frequency the number of exceptions is checked and an alert is created if this number is bigger than 0. If you want to reduce the number of alert for these metrics, you could increase the value for the calculation frequency to increase the time between checks.
For interfaces of type RFC the following metrics are collected:
