Description Beat Rubischon 2018-05-18 14:26:50 UTC
Description of problem:

The setting PMLOGGER_LOCAL=1 /etc/sysconfig/pmlogger is respected by the init script, but not by the daily cron job.

Version-Release number of selected component (if applicable):

pcp-3.11.8-7.el7.x86_64

How reproducible:

always

Steps to Reproduce:
1. Install pcp-zerofonf
2. Set PMLOGGER_LOCAL=1 in /etc/sysconfig/pmlogger
3. check for open ports

# ss -tulpen | grep pmlogger
tcp    LISTEN     0      5      127.0.0.1:4330                  *:*                   users:(("pmlogger",pid=6160,fd=7)) uid:997 ino:22879 sk:ffff880079879740 <->
tcp    LISTEN     0      5       ::1:4330                 :::*                   users:(("pmlogger",pid=6160,fd=8)) uid:997 ino:22880 sk:ffff880079871100 v6only:1 <->

4. Run daily rotation, check for open ports

# su pcp -s /bin/bash -c "/usr/libexec/pcp/bin/pmlogger_daily -X xz -x 1"
# ss -tulpen | grep pmlogger
tcp    LISTEN     0      5         *:4330                  *:*                   users:(("pmlogger",pid=6554,fd=7)) uid:997 ino:25333 sk:ffff8800781d87c0 <->
tcp    LISTEN     0      5        :::4330                 :::*                   users:(("pmlogger",pid=6554,fd=8)) uid:997 ino:25334 sk:ffff8800781d1100 v6only:1 <->


Actual results:

tcp    LISTEN     0      5         *:4330                  *:*                   users:(("pmlogger",pid=6554,fd=7)) uid:997 ino:25333 sk:ffff8800781d87c0 <->
tcp    LISTEN     0      5        :::4330                 :::*                   users:(("pmlogger",pid=6554,fd=8)) uid:997 ino:25334 sk:ffff8800781d1100 v6only:1 <->

Expected results:

tcp    LISTEN     0      5      127.0.0.1:4330                  *:*                   users:(("pmlogger",pid=6160,fd=7)) uid:997 ino:22879 sk:ffff880079879740 <->
tcp    LISTEN     0      5       ::1:4330                 :::*                   users:(("pmlogger",pid=6160,fd=8)) uid:997 ino:22880 sk:ffff880079871100 v6only:1 <->

    pmnewlog: honour any /etc/sysconfig/pmlogger settings
    
    Missed a spot in the PMLOGGER_LOCAL implementation - it
    previously was being honoured by pmlogger_check script,
    but not pmlogger_daily - tweak pmnewlog to resolve this
    and start the primary pmlogger consistently.
    
    Resolves Red Hat BZ #1579881.
