commit 55e8c83ee5920ab30644f54f7a525255b1de4b84

docs: describe working sudoers configuration with requiretty
When /etc/sudoers is configured with 'Defaults requiretty',
pmlogctl cannot invoke pmlogger_check in the normal fashion.
Symptoms of the problem are the following system log message:
pmlogctl[PID]: sudo: sorry, you must have a tty to run sudo
pmiectl and pmie_check are similarly affected. The simplest
solution is to add an additional configuration line excluding
these commands from requiring a tty; this is the approach now
documented.
Note these PCP commands are not interactive (require no tty)
and the unprivileged 'pcp' account uses nologin(8) as a shell
anyway, so requiretty offers no advantages here. Note also
there's debate about whether requiretty is a useful security
measure in general as it can be trivially bypassed; further
details: https://bugzilla.redhat.com/show_bug.cgi?id=1020147

From 73c024c64f7db68fdcd224c27c1711fa6dd1d254 Mon Sep 17 00:00:00 2001

Subject: [PATCH] pmlogger_farm: add default configuration file for farm
loggers
Provide a mechanism whereby the farm loggers can be configured.
There has been reluctance in the past to sharing configuration
of the local primary logger, so these are now done separately.
Makes sense to me as the primary pmlogger may need to use more
frequent sampling, may not want to allow remote pmlc, etc.
