Kubernetes scheduler π
The Splunk Distribution of OpenTelemetry Collector uses the Smart Agent receiver with the kubernetes-proxy
monitor type to export Prometheus metrics from the kube-scheduler.
This monitor type is available on Kubernetes, Linux, and Windows.
Benefits π
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 Splunk 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 Use navigators in Splunk Infrastructure Monitoring.
Access the Metric Finder and search for metrics sent by the monitor. For information, see Search the Metric Finder and Metadata catalog.
Installation π
Follow these steps to deploy this integration:
Deploy the Splunk Distribution of OpenTelemetry Collector to your host or container platform:
Configure the monitor, as described in the Configuration section.
Restart the Splunk Distribution of OpenTelemetry Collector.
Configuration π
To use this integration of a Smart Agent monitor with the Collector:
Include the Smart Agent receiver in your configuration file.
Add the monitor type to the Collector configuration, both in the receiver and pipelines sections.
Read more on how to Use Smart Agent monitors with the Collector.
See how to set up the Smart Agent receiver.
Learn about config options in Collector default configuration.
Example π
To activate this integration, add the following to your Collector configuration:
receivers:
smartagent/kubernetes-scheduler
type: kubernetes-scheduler
... # Additional config
Next, add the monitor to the service.pipelines.metrics.receivers
section of your configuration file:
service:
pipelines:
metrics:
receivers: [smartagent/kubernetes-scheduler]

Send all the metrics that come out of the Prometheus exporter without any filtering. This option has no effect when using the prometheus exporter monitor directly since there is no built-in filtering, only when embedding it in other monitors. Default is |
Metrics π
The following metrics are available for this integration:
Notes π
To learn more about the available in Observability Cloud see Metric types.
In host-based subscription plans, default metrics are those metrics included in host-based subscriptions in Observability Cloud, such as host, container, or bundled metrics. Custom metrics are not provided by default and might be subject to charges. See Metric categories for more information.
In MTS-based subscription plans, all metrics are custom.
To add additional metrics, see how to configure
extraMetrics
in Add additional metrics.
Non-default metrics (version 4.7.0+) π
To emit metrics that are not default, you can add those metrics in the generic monitor-level extraMetrics
config option. Metrics that are derived from specific configuration options that do not appear in the above list of metrics do not need to be added to extraMetrics
.
To see a list of metrics that will be emitted you can run agent-status monitors
after configuring this monitor in a running agent instance.
