# System Input Plugin
|
|
|
|
|
|
|
|
|
|
The system plugin gathers general stats on system load, uptime,
|
2018-04-18 23:55:18 +00:00
|
|
|
and number of users logged in. It is similar to the unix `uptime` command.

### Configuration:
|
|

|
|
|
```toml
|
|
|
|
|
# Read metrics about system load & uptime
|
|
|
|
|
[[inputs.system]]
|
|
|
|
|
# no configuration

|
|
The `n_users` field requires read access to `/var/run/utmp`, and may require
|

|
|
|
the `telegraf` user to be added to the `utmp` group on some systems. If this file does not exist `n_users` will be skipped.
