Windows Monitoring

SkyWalking leverages Prometheus windows_exporter to collect metrics data from the Windows and leverages OpenTelemetry Collector to transfer the metrics to OpenTelemetry receiver and into the Meter System. Windows entity as a Service in OAP and on the Layer: OS_WINDOWS.

Data flow

For OpenTelemetry receiver:

  1. The Prometheus windows_exporter collects metrics data from the VMs.
  2. The OpenTelemetry Collector fetches metrics from windows_exporter via Prometheus Receiver and pushes metrics to the SkyWalking OAP Server via OpenTelemetry gRPC exporter.
  3. The SkyWalking OAP Server parses the expression with MAL to filter/calculate/aggregate and store the results.


For OpenTelemetry receiver:

  1. Setup Prometheus windows_exporter.
  2. Setup OpenTelemetry Collector . This is an example for OpenTelemetry Collector configuration otel-collector-config.yaml.
  3. Config SkyWalking OpenTelemetry receiver.
