Pmlogger is creating world-readable log files in /var/log/pcp/pmlogger

Issue

• pcp component pmlogger is creating world-readable log files in /var/log/pcp/pmlogger.
• Security vulnerability scanners (notable CIS Benchmark assessor tool, and possibly Rapid7), are calling out these files, asserting that they should have NO world access, read or otherwise.
• Expecting that OS distribution products would comply with CIS standards.
• What is the way to configure pmlogger to change the mode in which it creates said logs; if there is a way, we would be glad to know of it, if there is not a way, would like to see this corrected.
• cockpit-pcp will not display historic performance metrics from pmlogger
