Monitoring Availability

System availability can be defined on differently depending on the technology layer: Following a bottom up approach, the lowest level of system availability is the existence of the corresponding processes on Operating System layer. Higher on the technology stack is a ping or a dummy login into a system. On application level, there may exist a real business availability check. SAP offers powerful availability checks on all layers.

For general information about monitoring, see Monitoring your SAP NetWeaver Components.
