Bug ID: 1323521
Summary: remote operation of pmie based pmda restarter
interferes with local pmcd
Product: Fedora
Version: rawhide
Component: pcp
Assignee: nathans@xxxxxxxxxx
Reporter: fche@xxxxxxxxxx

The workaround for bug #1065803 (proc-pmda hanging/timing-out) was for some
reason to write a pmie rule that pmsignals pmcd if a pmda-monitoring metric
indicates a damaged pmda.
This rule is ignorant of whether it's running against a local pmcd, or a remote
one (so it has no hope at all of signalling the remote pmcd). pmieconf does
not take a -h HOST parameter either, so cannot express a different ruleset for
local vs. remote pmie targets.
The effect of the new status quo is to have a default-configured "pmie -h
REMOTE" job send HUP signals to an innocent local pmcd ... and do nothing about
the suffering remote pmcd.
(I remain convinced that pmda restarting ought to be performed by logic within
the local pmcd, and not require external imperfect assistance.)
