System Input Plugin

The system plugin gathers general stats on system load, uptime, and number of users logged in. It is similar to the unix uptime command.

Number of CPUs is obtained from the /proc/cpuinfo file.

Global configuration options

In addition to the plugin-specific configuration settings, plugins support additional global and plugin configuration settings. These settings are used to modify metrics, tags, and field or create aliases and configure ordering, etc. See the CONFIGURATION.md for more details.

Configuration

# Read metrics about system load & uptime
[[inputs.system]]
  # 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.

Metrics

  • system
    • fields:
      • load1 (float)
      • load15 (float)
      • load5 (float)
      • n_users (integer)
      • n_unique_users (integer)
      • n_cpus (integer)
      • uptime (integer, seconds)
      • uptime_format (string, deprecated in 1.10, use uptime field)

Example Output

system,host=tyrion load1=3.72,load5=2.4,load15=2.1,n_users=3i,n_cpus=4i 1483964144000000000
system,host=tyrion uptime=1249632i 1483964144000000000
system,host=tyrion uptime_format="14 days, 11:07" 1483964144000000000
