The APM ETL process
extracts performance metric information from various SAS server logs.
After the information is extracted, it is loaded into the SAS Environment
Manager Data Mart. As with other information in the data mart, you can use this information
to
produce predefined reports or to conduct custom analysis and reporting.
APM extracts the data
from the SAS logs only when the logs roll over at midnight, so the
metric data and the reports display forensic or historical data. It
provides a look back at how things have been running, rather than
a real-time look at how things are currently running. Reports that are produced by
APM
display the following kinds
of information:
-
the most heavily used SAS procedures
-
the top ten users of the SAS Workspace
Server
-
the number of times per day each user ID has
accessed the SAS Metadata Server
-
each instance of an authentication error
or of an unauthorized
login attempt
-
The response time and run time
for SAS stored processes
Note: Enabling the APM ETL process causes a separate log to be
created for each spawned SAS Workspace Server. You must plan for the
large number of log files that
this process creates.
A best practice is to create a daily archive file of the day’s
log files, and then to copy
the file to archive storage.
