Performance Co-Pilot (PCP) on my RHEL server to capture performance logs<\/h1>\n

 <\/p>\n

RHEL 7 (prior to RHEL 7.4)<\/h2>\n

PCP is included in the base RHEL and Fedora distributions. A minimal installation requires just the pcp package (and its dependencies) to enable performance data logs to be collected for later analysis:<\/p>\n
