Description 🔗

The Splunk Distribution of OpenTelemetry Collector provides this integration as the aspdotnet monitor for the Smart Agent Receiver.

Use this integration to retrieve metrics for requests, errors, sessions, and worker processes from ASP.NET applications.

This monitor 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.

Windows Performance Counters 🔗

Windows Performance Counters are the source of retrieved metrics. Most of the performance counters in this monitor are gauges that represent rates per second and percentages.

This monitor reports the instantaneous values of these Windows Performance Counters. 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.
