+# System Integration
+
+The System module allows you to monitor your servers. Because the System module
+always applies to the local server, the `hosts` config option is not needed.
+
+The default metricsets are `cpu`, `load`, `memory`, `network`, `process`, and
+`process_summary`. To disable a default metricset, comment it out in the
+`modules.d/system.yml` configuration file. If _all_ metricsets are commented out
+and the System module is enabled, {beatname_uc} uses the default metricsets.
+
+Note that certain metricsets may access `/proc` to gather process information,
+and the resulting `ptrace_may_access()` call by the kernel to check for
+permissions can be blocked by
+https://gitlab.com/apparmor/apparmor/wikis/TechnicalDoc_Proc_and_ptrace[AppArmor
+and other LSM software], even though the System module doesn't use `ptrace`
+directly.
+
+## Compatibility
+
+The System metricsets collect different kinds of metric data, which may require dedicated permissions
+to be fetched and which may vary across operating systems.
+
+## Metrics
+
+### Core
+
+The System `core` metricset provides usage statistics for each CPU core.
+
+This metricset is available on:
+
+- FreeBSD
+- Linux
+- macOS
+- OpenBSD
+- Windows
+
+{{fields "core"}}
+
+
+### CPU
+
+The System `cpu` metricset provides CPU statistics.
+
+This metricset is available on:
+
+- FreeBSD
+- Linux
+- macOS
+- OpenBSD
+- Windows
+
+{{fields "cpu"}}
+
+### diskio
+
+The System `diskio` metricset provides disk IO metrics collected from the
+operating system. One event is created for each disk mounted on the system.
+
+This metricset is available on:
+
+- Linux
+- macOS (requires 10.10+)
+- Windows
+- FreeBSD (amd64)
+
+{{fields "diskio"}}
+
+### entropy
+
+This is the entropy metricset of the module system. 
+It collects the amount of available entropy in bits. On kernel versions greater than 2.6, 
+entropy will be out of a total pool size of 4096.
+
+This Metricset is available on:
+
+- linux
+
+{{fields "entropy"}}
+
+### filesystem
+
+The System `filesystem` metricset provides file system statistics. For each file
+system, one document is provided.
+
+This metricset is available on:
+
+- FreeBSD
+- Linux
+- macOS
+- OpenBSD
+- Windows
+
+{{fields "filesystem"}}
+
+### fsstat
+
+The System `fsstat` metricset provides overall file system statistics.
+
+This metricset is available on:
+
+- FreeBSD
+- Linux
+- macOS
+- OpenBSD
+- Windows
+
+{{fields "fsstat"}}
+
+### load
+
+The System `load` metricset provides load statistics.
+
+This metricset is available on:
+
+- FreeBSD
+- Linux
+- macOS
+- OpenBSD
+
+{{fields "load"}}
+
+### memory
+
+The System `memory` metricset provides memory statistics.
+
+This metricset is available on:
+
+- FreeBSD
+- Linux
+- macOS
+- OpenBSD
+- Windows
+
+{{fields "memory"}}
+
+### network
+
+The System `network` metricset provides network IO metrics collected from the
+operating system. One event is created for each network interface.
+
+This metricset is available on:
+
+- FreeBSD
+- Linux
+- macOS
+- Windows
+
+{{fields "network"}}
+
+### network_summary
+
+The System `network_summary` metricset provides network IO metrics collected from the
+operating system. These events are global and sorted by protocol.
+
+This metricset is available on:
+
+- Linux
+
+{{fields "network_summary"}}
+
+### process
+
+The System `process` metricset provides process statistics. One document is
+provided for each process.
+
+This metricset is available on:
+
+- FreeBSD
+- Linux
+- macOS
+- Windows
+
+{{fields "process"}}
+
+### process_summary
+
+The `process_summary` metricset collects high level statistics about the running
+processes.
+
+This metricset is available on:
+
+- FreeBSD
+- Linux
+- macOS
+- Windows
+
+{{fields "process_summary"}}
+
+### raid
+
+This is the raid metricset of the module system. It collects stats about the raid.
+
+This metricset is available on:
+
+- Linux
+
+{{fields "raid"}}
+
+### service
+
+The `service` metricset reports on the status of systemd services.
+
+This metricset is available on:
+
+- Linux
+
+{{fields "service"}}
+
+### socket
+
+This metricset is available on Linux only and requires kernel 2.6.14 or newer.
+
+The system `socket` metricset reports an event for each new TCP socket that it
+sees. It does this by polling the kernel periodically to get a dump of all
+sockets. You set the polling interval by configuring the `period` option.
+Specifying a short polling interval with this metricset is important to avoid
+missing short-lived connections.
+
+{{fields "socket"}}
+
+### socket_summary
+
+The System `socket_summary` metricset provides the summary of open network
+sockets in the host system.
+
+It collects a summary of metrics with the count of existing TCP and UDP
+connections and the count of listening ports.
+
+This metricset is available on:
+
+- FreeBSD
+- Linux
+- macOS
+- Windows
+
+{{fields "socket_summary"}}
+
+### uptime
+
+The System `uptime` metricset provides the uptime of the host operating system.
+
+This metricset is available on:
+
+- Linux
+- macOS
+- OpenBSD
+- FreeBSD
+- Windows
+
+{{fields "uptime"}}
+
+### users
+
+The system/users metricset reports logged in users and associated sessions via dbus and logind, which is a systemd component. By default, the metricset will look in `/var/run/dbus/` for a system socket, although a new path can be selected with `DBUS_SYSTEM_BUS_ADDRESS`.
+
+This metricset is available on:
+
+- Linux
+
+{{fields "users"}}
