Microsoft .NET 🔗

The Splunk Distribution of OpenTelemetry Collector uses the Smart Agent receiver with the dotnet monitor type to report metrics for .NET applications.

This integration is only available on Windows.

This integration reports the instantaneous values for Windows Performance Counters. Most of these performance counters are gauges that represent rates per second and percentages. This means that in a collection interval, spikes might occur on the Performance Counters. The best way to mitigate this limitation is to increase the reporting interval on this monitor to collect more frequently.

The following is a list of the most critical .NET performance counters:

  • Exceptions

  • Logical threads

  • Physical threads

  • Heap bytes

  • Time in GC

  • Committed bytes

  • Pinned objects

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.

Installation 🔗

Follow these steps to deploy this integration:

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

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

  3. Restart the Splunk Distribution of OpenTelemetry Collector.

Configuration 🔗

To use this integration of a Smart Agent monitor with the Collector:

  1. Include the Smart Agent receiver in your configuration file.

  2. Add the monitor type to the Collector configuration, both in the receiver and pipelines sections.

Example 🔗

To activate this integration, add the following to your Collector configuration:

    type: dotnet
    ...  # Additional config

Next, add the monitor to the service.pipelines.metrics.receivers section of your configuration file:

     receivers: [smartagent/dotnet]

Configuration settings 🔗

The following table shows the configuration options for this integration:








Number of seconds that wildcards in counter paths should be expanded and how often to refresh counters from configuration. (default: 60s)




Print out the configurations that match available performance counters. This option is used for debugging. (default: false)

Metrics 🔗

This integration emits all metrics by default, but they are categorized as custom metrics. See the notes for more details.

Notes 🔗

  • Learn more about the available metric types in Observability Cloud.

  • 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 more about metric categories.

  • To add additional metrics, see how to configure extraMetrics using the Collector.
