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.

Setup

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.

Customizing

You can customize your own metrics/expression/dashboard panel. The metrics definition and expression rules are found in /config/otel-rules/windows.yaml. The dashboard panel confirmations are found in /config/ui-initialized-templates/os_windows.
