DESCRIPTION

16       An  application  using  the Performance Metrics Application Programming
17       Interface (PMAPI) may  manipulate  several  concurrent  contexts,  each
18       associated  with  a source of performance metrics, e.g. pmcd(1) on some
19       host, or a set of archive logs of performance  metrics  as  created  by
20       pmlogger(1).
21
22       Calling  pmDupContext will replicate the current PMAPI context, return‐
23       ing a handle for the new context that may be used with subsequent calls
24       to pmUseContext(3).
25
26       Once  created,  the  duplicated  context  and the original context have
27       independent existence, and so their instance  profiles  and  collection
28       time (relevant only for archive contexts) may be independently varied.
29
30       The newly replicated context becomes the current context.
