Chrony NTP 🔗

Description 🔗

The Splunk Distribution of OpenTelemetry Collector provides this integration as the Chrony NTP monitor type by using the SignalFx Smart Agent receiver. The integration monitors NTP data from a chrony server, such as clock skew and per-peer stratum. For talking to chronyd, this monitor type mimics what the chronyc control program does on the wire.

This integration is available for Kubernetes, Linux, and Windows.

Benefits 🔗

Installation 🔗

Follow these steps to deploy this integration:

  1. Deploy the Splunk Distribution of OpenTelemetry Collector to your host or container platform:

  2. Configure the monitor, as described in the Configuration section.

  3. Restart the Splunk Distribution of OpenTelemetry Collector.

Configuration 🔗

This monitor type is available in the Smart Agent Receiver, which is part of the Splunk Distribution of OpenTelemetry Collector. You can use existing Smart Agent monitors as OpenTelemetry Collector metric receivers with the Smart Agent Receiver.

This monitor type requires a properly configured environment on your system in which you’ve installed a functional Smart Agent release bundle. The Collector provides this bundle in the installation paths for x86_64/amd64.

To activate this monitor type in the Collector, add the following lines to your configuration (YAML) file:

receivers:
  smartagent/chrony:
    type: collectd/chrony
    ...  # Additional config

To complete the integration, include the monitor type in a metrics pipeline. Add the monitor type to the service/pipelines/metrics/receivers section of your configuration file. For example:

service:
 pipelines:
   metrics:
     receivers: [smartagent/chrony]
