Monitor
The monitor function performs the following tasks:
Validates the values of the agent attributes required to monitor the SAP instance.
Performs a first-level monitor check as follows:
The function verifies that the SAP Windows service SAPSAPSID_InstID is running, where InstID is the last two characters of the InstName attribute.
Verifies that all processes that the ProcMon attribute lists are running.
If the value of SecondLevelMonitor attribute is greater than 0, the monitor function performs a more thorough check of the SAP instance as follows:
For APPSERV instances, the function uses the following utilities to perform this check:
SAPWeb Application Server as ABAP
sapcontrol.exe
SAPWeb Application Server as Java
sapcontrol.exe
SAPWeb Application Server as Add-In
sapcontrol.exe
For an Enqueue or Enqueue Replication server instance, the function uses the ensmon.exe utility.
If the MonitorProgram attribute specifies a custom monitor program, the monitor function executes the specified program.
