ASP.NET (deprecated) 🔗

Caution

This integration is deprecated and reached End of Support in February 2025. It was removed from the Splunk Distribution of the OpenTelemetry Collector starting from version v0.118.0.

To forward data from a .NET application to Splunk Observability Cloud use the Splunk Distribution of OpenTelemetry .NET instead.

To monitor Windows Performance Counters with native OpenTelemetry refer to Windows Performance Counters receiver.

The Splunk Distribution of the 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.
