Chrony NTP 🔗

The Splunk Distribution of OpenTelemetry Collector uses the Smart Agent receiver with the Chrony NTP monitor type to monitor NTP data from a chrony server, such as clock skew and per-peer stratum. To talk to chronyd, this integration mimics what the chronyc control program does on the wire.

This integration is only available on Kubernetes and Linux.

Benefits 🔗

After you configure the integration, you can access these features:

View metrics. You can create your own custom dashboards, and most monitors provide built-in dashboards as well. For information about dashboards, see View dashboards in Observability Cloud.
View a data-driven visualization of the physical servers, virtual machines, AWS instances, and other resources in your environment that are visible to Infrastructure Monitoring. For information about navigators, see Splunk Infrastructure Monitoring navigators.
Access the Metric Finder and search for metrics sent by the monitor. For information, see Use the Metric Finder.
