--- Comment #1 from Mark Goodwin <[email protected]> ---

That patch looks good to me and is basically the agreed solution as discussed
http://www.pcp.io/pipermail/pcp/2016-May/010545.html i.e. turn off derived
metrics in pmlogconf by setting PCP_DERIVED_CONFIG to an empty string, along
with suitable man page updates. Not sure if we'd still want to honor
PCP_DERIVED_CONFIG if it is already set to something (as opposed to not being
set) ??

I don't see how reimplementing pmlogconf in another language will reduce the
probe overheads - we'd still have the same number of probes being called, which
is surely where most of the time is being spent. But the above patch should
help.
