Hi -
We keep hearing regular calls for pcp operation mode where an
application is interested in both historical and live data regarding a
host. The PMAPI's and pcp clients' complete bifurcation between -h/-a
is contrary to this goal.
This is not a new topic. [1....]. The main related bits of progress
we've made have been the multi-archive libpcp mode and the pmwebd
server, but much more remains. It would be nice to come to some
general points of agreement and make some progress again.
Amongst the high-level questions:
- Does the pcp developer community agree that there is a need, and
that the status quo is not sufficient?
- Should the functionality include remote access to archive+live mode,
in the sense that remote archives could be a data source?
- How soon?
- Are there subsets of functionality that could go into peripheral PCP
tools while waiting for core PCP for a fuller solution?
- Should we consider older parts of PCP (pmlogger, pmcd core) apprx.
untouchable, so extra functionality would need to go into new
tools/services rather than extending old ones?
