The system metrics Netdata users interact with most for health monitoring and +performance troubleshooting are collected and visualized by `proc.plugin`, `cgroups.plugin`, and `ebpf.plugin`. + +[**proc.plugin**](/collectors/proc.plugin/README.md) gathers metrics from the `/proc` and `/sys` folders in Linux +systems, along with a few other endpoints, and is responsible for the bulk of the system metrics collected and +visualized by Netdata. It collects CPU, memory, disks, load, networking, mount points, and more with zero configuration. +It even allows Netdata to monitor its own resource utilization! + +[**cgroups.plugin**](/collectors/cgroups.plugin/README.md) collects rich metrics about containers and virtual machines +using the virtual files under `/sys/fs/cgroup`. By reading cgroups, Netdata can instantly collect resource utilization +metrics for systemd services, all containers (Docker, LXC, LXD, Libvirt, systemd-nspawn), and more. Learn more in the +[collecting container metrics](/docs/collect/container-metrics.md) doc. + +[**ebpf.plugin**](/collectors/ebpf.plugin/README.md): Netdata's extended Berkeley Packet Filter (eBPF) collector +monitors Linux kernel-level metrics for file descriptors, virtual filesystem IO, and process management. You can use our +eBPF collector to analyze how and when a process accesses files, when it makes system calls, whether it leaks memory or +creating zombie processes, and more. + +While the above plugins and associated collectors are the most important for system metrics, there are many others. You +can find all system collectors in our [supported collectors list](/collectors/COLLECTORS.md#system-metrics). + +## Collect Windows system metrics + +Netdata is also capable of monitoring Windows systems. The [WMI +collector](https://learn.netdata.cloud/docs/agent/collectors/go.d.plugin/modules/wmi) integrates with +[windows_exporter](https://github.com/prometheus-community/windows_exporter), a small Go-based binary that you can run +on Windows systems. The WMI collector then gathers metrics from an endpoint created by windows_exporter. + +First, [download windows_exporter](https://github.com/prometheus-community/windows_exporter#installation) and run it +with the following collectors enabled, changing `0.14.0` to the version you downloaded. + +```powershell +windows_exporter-0.14.0-amd64.exe --collectors.enabled="cpu,memory,net,logical_disk,os,system,logon" +``` + +Next, [configure the WMI +collector](https://learn.netdata.cloud/docs/agent/collectors/go.d.plugin/modules/wmi#configuration) to point to the URL +and port of your exposed endpoint. Restart Netdata with `service netdata restart` and you'll start seeing Windows system +metrics, such as CPU utilization, memory, bandwidth per NIC, number of processes, and much more. + +For information about collecting metrics from applications _running on Windows systems_, see the [application metrics +doc](/docs/collect/application-metrics.md#collect-metrics-from-applications-running-on-windows). + +## What's next? + +Because there's some overlap between system metrics and [container metrics](/docs/collect/container-metrics.md), you +should investigate Netdata's container compatibility if you use them heavily in your infrastructure. + +If you don't use containers, skip ahead to collecting [application metrics](/docs/collect/application-metrics.md) with +Netdata. + +[![analytics](https://www.google-analytics.com/collect?v=1&aip=1&t=pageview&_s=1&ds=github&dr=https%3A%2F%2Fgithub.com%2Fnetdata%2Fnetdata&dl=https%3A%2F%2Fmy-netdata.io%2Fgithub%2Fdocs%2Fcollect%2Fsystem-metrics&_u=MAC~&cid=5792dfd7-8dc4-476b-af31-da2fdb9f93d2&tid=UA-64295674-3)](<>) |
