You can use WLST DMS Custom commands to periodically save DMS metric information to a file so that you have a record of past metric values.
The implementation of the DMS commands are in the python file: Middleware\oracle_common\common\ojbst\lib\OracleDMS.py
The wlst script must be started from this directory:
Middleware_Home\oracle_common\common\bin>wlst.cmd
connect('weblogic','password','host:7001')
metricTableNames = displayMetricTableNames()
obiMetricTableNames = [i for i in metricTableNames if 'Oracle_BI' in i]
for i in obiMetricTableNames: print i

You get a list of metrics block separated by a white line. The key by block is the attribute “Name”.
