Chrony receiver 🔗

The Chrony receiver is a pure Go implementation of the command chronyc tracking which allows portability across systems and platforms. The receiver produces all of the metrics that would typically be captured by the tracking command.

For more information about Chrony, see Red Hat’s Chrony suite documentation .

Get started 🔗

Follow these steps to configure and activate the component:

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

Install the Collector for Linux with the installer script

Install the Collector for Windows with the installer script

Install the Collector for Kubernetes using Helm

Configure the Chrony receiver as described in the next section.
Restart the Collector.

Default configuration 🔗

To activate the receiver, add chrony to the receivers section of your configuration file:

receivers:
  chrony/defaults:
    endpoint: unix:///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

Next, include the receiver in the metrics pipeline of the service section of your configuration file:

service:
  pipelines:
    metrics:
      receivers:
        - chrony

Advanced configuration 🔗

You can use the following settings:

endpoint. Required. The address where chrony communicates to. Allowed formats are:
- udp://hostname:port
- unixgram:///path/to/chrony/sock
- unix:///path/to/chrony.sock - Note the triple slash. Unix is converted to unixgram.
timeout. Optional. The total amount of time allowed to read and process the data from chronyd. Use at least 1 second.
collection_interval. Optional. Determines how often to query Chrony.
initial_delay. Optional. 1s by default. Defines how long this receiver waits before starting. See more in Red Hat’s Chrony suite documentation .
metrics. Optional. Metrics to export. See the metric documentation in GitHub .

Configuration example 🔗

See the following configuration example:

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

Settings 🔗

The following table shows the configuration options for the Chrony receiver:

Metrics 🔗

The following metrics, resource attributes, and attributes, are available.

See also the metric documentation in GitHub .

Activate or deactivate specific metrics 🔗

You can activate or deactivate specific metrics by setting the enabled field in the metrics section for each metric. For example:

receivers:
  samplereceiver:
    metrics:
      metric-one:
        enabled: true
      metric-two:
        enabled: false

The following is an example of host metrics receiver configuration with activated metrics:

receivers:
  hostmetrics:
    scrapers:
      process:
        metrics:
          process.cpu.utilization:
            enabled: true

Note

Deactivated metrics aren’t sent to Splunk Observability Cloud.

Billing 🔗

If you’re in a MTS-based subscription, all metrics count towards metrics usage.
If you’re in a host-based plan, metrics listed as active (Active: Yes) on this document are considered default and are included free of charge.

Learn more at Infrastructure Monitoring subscription usage (Host and metric plans).
