+# Windows
+
+The [Windows addon](../examples/windows.jsonnet) adds the dashboards and rules from [kubernetes-monitoring/kubernetes-mixin](https://github.com/kubernetes-monitoring/kubernetes-mixin#dashboards-for-windows-nodes).
+
+Currently, Windows does not support running with [windows_exporter](https://github.com/prometheus-community/windows_exporter) in a pod so this add on uses [additional scrap configuration](https://github.com/prometheus-operator/prometheus-operator/blob/master/Documentation/additional-scrape-config.md) to set up a static configs to scrape the node ports where windows_exporter is configured.
+
+The addon requires you to specify the node ips and ports where it can find the windows_exporter. See the [full example](../examples/windows.jsonnet) for setup.

+local kp = (import 'kube-prometheus/main.libsonnet') +
+ (import 'kube-prometheus/addons/windows.libsonnet') +

+ windowsScrapeConfig+:: {
+ static_configs: {
+ targets: ["10.240.0.65:5000", "10.240.0.63:5000"],
+ },
+ },
+ },
+ };
