Yes, as a workaround delete all logs in /var/log/pcp/HOSTNAME/* I need to fix this. So Nathan from PCP identified the issue in MVV/PCP codebase, we have a patch that was merged upstream. I asked PCP guys to backport it into RHEL 7.5: https://bugzilla.redhat.com/show_bug.cgi?id=1586051 In the meantime, you can continue testing with this PCP version: https://copr.fedorainfracloud.org/coprs/lzap/pcp/ Just drop the repo file and upgrade all pcp packages, restart all services: rm -rf /var/log/pcp/pmlogger/*/* systemctl restart pmcd pmlogger pmie pmwebd And start over with testing. Make sure this command does not print any error after one hour or one week of uptime: echo "log mandatory on 30seconds mmv" | /usr/bin/pmlc -P Connected to primary pmlogger at local: You should see lots of mmv metrics: pminfo | grep mmv Also Grafana should work fine. If you don't see a metric which you expect, just run the "pmlc" command from above and it will show up.

No errors were observed in log. I feel this bug should still kept ON_QA until tested with 7.6 GA build, to be sure we don't miss anything when we announce the feature after/for 7.6 GA Build: Satellite 6.5.0 snap 8 on RHEL7.6 rpm -qa | grep pcp pcp-4.1.0-5.el7_6.x86_64 pcp-conf-4.1.0-5.el7_6.x86_64 pcp-mmvstatsd-0.4-2.el7sat.x86_64 pcp-libs-4.1.0-5.el7_6.x86_64 pcp-webapp-grafana-4.1.0-5.el7_6.noarch pcp-selinux-4.1.0-5.el7_6.x86_64 pcp-webapp-vector-4.1.0-5.el7_6.noarch pcp-pmda-apache-4.1.0-5.el7_6.x86_64 pcp-webapi-4.1.0-5.el7_6.x86_64 The logger didn't error and was functioning after 48 hours.
