System Input Plugin

This plugin gathers general system statistics like system load, uptime or the number of users logged in. It is similar to the unix uptime command.

  # no configuration

Permissions

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.

The n_unique_users shows the count of unique usernames logged in. This way if a user has multiple sessions open/started they would only get counted once. The same requirements for n_users apply.
