To gather system metrics, Netdata uses roughly a dozen plugins, each of which has one or more collectors for very specific metrics exposed by the host. 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 +[**proc.plugin**](https://github.com/netdata/netdata/blob/master/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 +[**cgroups.plugin**](https://github.com/netdata/netdata/blob/master/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.

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.
