The Splunk Distribution of OpenTelemetry Collector uses the Smart Agent receiver with the aspdotnet monitor type to retrieve metrics for requests, errors, sessions, and worker processes from ASP.NET applications.

This integration reports the instantaneous values of Windows Performance Counters, which are the source of the retrieved metrics. Most of the performance counters in this monitor are gauges that represent rates per second and percentages. Between collection intervals, spikes might occur in the Performance Counters. To mitigate the effect of these spikes, decrease the reporting interval on the monitor so that it collects more frequently.

This integration is only available on Windows.

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.

    ...  # Additional config

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

      receivers: [smartagent/aspdotnet]

Configuration settings 🔗

The following table shows the configuration options for this monitor:








This integer is the number of seconds that wildcards in counter paths should be expanded and how often to refresh counters from configuration. The default is 60s.




Use this flag to print out the configurations that match available performance counters. Use the flag for debugging. The default is false.
