Red Hat Bugzilla – Bug 1352461
PCP options -s and -T are mutually exclusive
Last modified: 2017-08-23 11:04:15 EDT
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 sam‐ 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.
This message is a reminder that Fedora 24 is nearing its end of life. Approximately 2 (two) weeks from now Fedora will stop maintaining and issuing updates for Fedora 24. It is Fedora's policy to close all bug reports from releases that are no longer maintained. At that time this bug will be closed as EOL if it remains open with a Fedora 'version' of '24'. Package Maintainer: If you wish for this bug to remain open because you plan to fix it in a currently maintained version, simply change the 'version' to a later Fedora version. Thank you for reporting this issue and we are sorry that we were not able to fix it before Fedora 24 is end of life. If you would still like to see this bug fixed and are able to reproduce it against a later version of Fedora, you are encouraged change the 'version' to a later Fedora version prior this bug is closed as described in the policy above. Although we aim to fix as many bugs as possible during every release's lifetime, sometimes those efforts are overtaken by events. Often a more recent Fedora release includes newer upstream software that fixes bugs or makes them obsolete.
This bug appears to have been reported against 'rawhide' during the Fedora 27 development cycle. Changing version to '27'.
