chrony

chrony Input Plugin

This plugin queries metrics from a chrony NTP server. For details on the meaning of the gathered fields please check the chronyc manual

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

# Get standard chrony metrics.
[[inputs.chrony]]
  ## Server address of chronyd with address scheme
  ## If empty or not set, the plugin will mimic the behavior of chronyc and
  ## check "unix:///run/chrony/chronyd.sock", "udp://127.0.0.1:323"
  ## and "udp://[::1]:323".
  # server = ""

  ## Timeout for establishing the connection
  # timeout = "5s"

  ## Try to resolve received addresses to host-names via DNS lookups
  ## Disabled by default to avoid DNS queries especially for slow DNS servers.
  # dns_lookup = false

  ## Metrics to query named according to chronyc commands
  ## Available settings are:
  ##   activity    -- number of peers online or offline
  ##   tracking    -- information about system's clock performance
  ##   serverstats -- chronyd server statistics
  ##   sources     -- extended information about peers
  ##   sourcestats -- statistics on peers
  # metrics = ["tracking"]

Metrics

• chrony
  • system_time (float, seconds)
  • last_offset (float, seconds)
  • rms_offset (float, seconds)
  • frequency (float, ppm)
  • residual_freq (float, ppm)
