As Nathan has suggested, if event traces are intended for retrospective
analysis (as opposed to event counters being suited for either real time
or retrospective analysis), then there is an alternative approach,
namely to create a PCP archive directly from a source of data without
involving pmcd or a pmda or pmlogger. We've recently reworked the
"pmimport" services to expose better APIs to support just this style of
use ... see LOGIMPORT(3) and sar2pcp(1) for an example. I think this
approach is possibly a better semantic match between PCP and a stream of
event records.
Hmm. If I'm understanding all the acronyms correctly, I'm not seeing
the benefit of using LOGIMPORT to create a PCP archive vs. involving
pcmd/pmda/pmlogger. Could you expand here?
