The Red Hat Enterprise Linux Performance Co-Pilot (PCP) utility selects and gathers the client-side usage metrics of the resource optimization (ROS) for Red Hat Lightspeed.

The insights-client detects the presence of the ROS PCP configuration file (/var/lib/pcp/config/pmlogger/config.ros). When it finds the file, it launches pmlogger to collect performance metrics data. PCP compiles these metrics into daily summaries. The RHEL pmlogger service then uploads the summaries to Red Hat Lightspeed for analysis.

By default, the config.ros configuration provides limited metrics with one data point per daily upload. Installing the RHEL pcp-zeroconf package for your version of RHEL enhances the data available to Red Hat Lightspeed and improves recommendations. The pcp-zeroconf package collects more detailed performance data, which enables more accurate Red Hat Lightspeed recommendations.

The pcp-zeroconf package automates PCP installation. After you install pcp-zeroconf, it automatically starts pmlogger. pmlogger gathers raw data on the default set of usage metrics and records the raw data into archive files.
