4.10 Notes
You can use any physical host instance to monitor performance data with the following record IDs, because this performance data is recorded for each SAP system:
-
PI_BTCP
-
PD_ALMX
-
PD_SRV
-
PI_UMP (depends on the performance monitor that is set)
If monitoring is performed with a single physical host, a failure on that host means monitoring can no longer continue. Therefore, we recommend that you use multiple physical hosts to perform monitoring concurrently.
However, when multiple physical hosts are used to perform monitoring concurrently, multiple alarms might occur for a single event. If this creates a problem, bind the alarm tables to a single physical host and, if a cluster failover occurs, switch the alarm table bindings from this physical host to the physical host where processing is being transferred.
