Memory Trace:
A New Transaction /SDF/MON will be used to trace the memory utilised by the instance based on Trace Duration.

16.Dispatcher Trace: ST11 
logging(Dispatcher and Processes Granularity is increased by using the parameter rdisp/TRACE=0,1,2,3.......
Ensure that the "work" directory has Enough Space.

Logging and Tracing:

by default the instance specific logs are written to the log in the directory
/usr/sap/SID/DVEBMGS00/log/SLOG. 

ABAP Dumps: When ever a program could not be executed it will Thrown as a Dump into Table SNAP. Table SNAP is reorganized by a report RSSNAPDL.
