PCP uses a collector–monitor architecture where Performance Metrics Domain Agents (PMDAs) gather data from different system subsystems and the Performance Metrics Collector Daemon (pmcd) coordinates collection. Metrics are archived by pmlogger for retrospective analysis. PCP replaces the legacy Oracle OSWatcher Black Box (OSWbb) and covers the same ground — CPU, memory, disk I/O, network, and process statistics — while offering binary archive storage, extensible PMDAs, conditional alerting via PMIE, and native Grafana integration. Distribution Compatibility Matrix PCP is included in the base repositories of all major RHEL-family distributions. Since RHEL 8, 9, and 10 all ship PCP in their BaseOS or AppStream repos, and Rocky Linux, AlmaLinux, and Oracle Linux maintain binary or ABI compatibility with RHEL, the ins...
