## What it is
Performance Co-Pilot (PCP) is a mature, cross-platform framework and toolkit for system-level performance monitoring and management. It unifies performance data collection from live systems and historical archives, with distributed client-server architecture and extensible metric agents.

## Use cases
- monitor cpu memory disk and network metrics across servers
- collect performance metrics from multiple hosts centrally
- replay and analyze historical performance data from archives
- extend monitoring with custom application metrics
- visualize system performance trends in grafana
- debug performance regressions on linux systems

## When to avoid
- you only need simple one-off checks like top or vmstat
- you want a turnkey SaaS-style monitoring dashboard with alerting out of the box
- your primary focus is application-level APM tracing rather than system metrics

## Facets
- artifact type: framework
- maturity: stable
- function: monitoring, analytics, tracing
- domain: monitoring, performance, microservices
- platform: windows, cross-platform, cli, self-hosted
- tags: performance-metrics, system-monitoring, time-series, pmcd, pmda, grafana-integration, archive-logging, devops, linux, macos
