Bug ID: 1352461
Summary: PCP options -s and -T are mutually exclusive
Product: Fedora
Version: 24
Component: pcp
Assignee: nathans@xxxxxxxxxx
Reporter: myllynen@xxxxxxxxxx
QA Contact: extras-qa@xxxxxxxxxxxxxxxxx

Description of problem:
$ pmrep -s 3 -T 1m -x -p -C mem.util.used
pmrep: at most one of -T and -s allowed
[...]
The same happens with other tools as well since this is coming from libpcp.
PCPIntro(1) does not describe this restriction and in fact some clients (like
pmrep(1)) would calculate the interval if -s and -T would be accepted together:
-T When reporting archived metrics, the report will be restricted to
those records logged before or at endtime. Refer to PCPIntro(1)
for a complete description of the syntax for endtime.
When used to define the runtime before pmrep will exit, if no samâ
ples is given (see -s) then the number of reported samples depends
on interval (see -t). If samples is given then interval will be
adjusted to allow reporting of samples during runtime. In case
all of -T, -s, and -t are given, endtime determines the actual
time pmrep will run.
