The OpenTelemetry Collector, when configured with a Prometheus receiver, provides an integration with IIS to scrape Prometheus metrics. The Collector uses the Prometheus Receiver to fetch metrics from the Windows Exporter endpoint. From there, the metrics are processed and exported to Lightstep Observability.

To complete the integration, perform the following steps:

  • Configure IIS and Windows Exporter with enabled IIS metrics
  • Configure the Collector to use the IIS Prometheus plugin endpoint as a scrape target for the Prometheus receiver
  • Enable the integration by adding it to a pipeline

Prerequisites

  • IIS running in a Kubernetes environment.
  • You’ve configured the Collector to export metric data to Lightstep Observability.

Configure IIS reporting

IIS requires use of Windows Exporter for exposing metrics in Prometheus format. See the IIS example for an integration.

Configure the Collector receiver

In the Collector configuration file, specify the IIS Prometheus plugin endpoint as a scrape target.

The OpenTelemetry repository readme provides additional details about Prometheus receiver configuration.

Complete information about the Prometheus scrape configuration can be found in the Prometheus documentation.

Enable the Collector receiver

After the IIS receiver is configured, enable it by adding it to one or more pipelines as described in the Collector configuration documentation.

Validate metrics are reporting to Lightstep

You can validate that metrics are reporting to Lightstep on the Metrics details page in Project settings.

  1. In Lightstep, click Project settings > Metric details.

  2. Search for IIS metric names. Search for metric

    See the Windows Exporter documentation for a detailed description of provided metrics.

  3. If needed, select the metric to edit the description and how the units are displayed in Lightstep.

Create a dashboard for the metrics

Use the Lightstep Terraform Provider to create a dashboard for the metrics.
