The chrony receiver is a pure go implementation of the command chronyc tracking to allow for portability across systems and platforms. All of the data that would typically be captured by the tracking command is made available in this receiver, see documentation for more details.

By default, the chrony receiver will default to the following configuration:

chrony/defaults:
  address: unix:https:///var/run/chrony/chronyd.sock # The default port by chronyd to allow cmd access
  timeout: 10s # Allowing at least 10s for chronyd to respond before giving up

chrony:
  # This will result in the same configuration as above

The following options can be customised:

• address (required) - the address on where to communicate to chronyd
  • The allowed formats are the following
    • udp:https://hostname:port
    • unix:https:///path/to/chrony.sock (Please note the triple slash)
    • unixgram:https:///path/to/chrony/sock
  • The network type unix will be converted to unixgram but both are permissible
• timeout (optional) - The total amount of time allowed to read and process the data from chronyd
  • Recommendation: This value should be set above 1s to allow chronyd time to respond
• collection_interval (optional) - how frequent this receiver should poll chrony
• initial_delay (default = 1s): defines how long this receiver waits before starting.
• metrics (optional) - Which metrics should be exported, read the documentation for complete details

An example of the configuration is:

receivers:
  chrony:
    address: unix:https:///var/run/chrony/chronyd.sock
    timeout: 10s
    collection_interval: 30s
    metrics:
      ntp.skew:
        enabled: true
      ntp.stratum:
        enabled: true

The complete list of metrics emitted by this receiver is found in the documentation.
