Microsoft Windows IIS 🔗

Description 🔗

The Splunk Distribution of OpenTelemetry Collector provides this integration using the windows-iis monitor with the smartagent receiver.

This monitor is only available on Windows. It reports metrics for Windows Internet Information Services (IIS) and drives the Windows IIS dashboard content.

Windows Performance Counters 🔗

The underlying source for these metrics are Windows Performance Counters. Most of the performance counters queried in this monitor are actually Gauges that represent rates per second and percentages.

This monitor reports the instantaneous values for these Windows Performance Counters. This means that in between a collection interval, spikes could 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.

Installation 🔗

This monitor is available in the Smart Agent Receiver, which is part of the Splunk Distribution of OpenTelemetry Collector.

To install this integration:

Deploy the Splunk Distribution of OpenTelemetry Collector to your host or container platform.
Configure the monitor, as described in the next section.

Configuration 🔗

The Splunk Distribution of OpenTelemetry Collector allows embedding a Smart Agent monitor configuration in an associated Smart Agent Receiver instance.

Note: Providing a windows-iis monitor entry in your Collector or Smart Agent (deprecated) configuration is required for its use. Use the appropriate form for your agent type.
