Available as of v2.5.8
Starting at Monitoring V2 14.5.100 (used by default in Rancher 2.5.8), Monitoring V2 can now be deployed on a Windows cluster and will scrape metrics from Windows nodes using prometheus-community/windows_exporter (previously named
Comparison to Monitoring V1
Unlike Monitoring V1 for Windows, metrics collected by
windows_exporter will be labeled as
windows_ instead of
wmi_ in accordance to a naming change from upstream from
In addition, Monitoring V2 for Windows will no longer require users to keep port 9796 open on Windows hosts since the host metrics will published directly onto a port exposed on the windows-exporter Pod. This feature was powered by recent changes made by
wins v0.1.0 to support publishing ports exposed on the hostNetwork on Pods that use wins to run a privileged Windows binary as a host process.
Monitoring V2 for Windows can only scrape metrics from Windows hosts that have a minimum
wins version of v0.1.0. To be able to fully deploy Monitoring V2 for Windows, all of your hosts must meet this requirement.
If you provision a fresh RKE1 cluster in Rancher 2.5.8, your cluster should already meet this requirement.
Upgrading Existing Clusters to wins v0.1.0
If the cluster was provisioned before Rancher 2.5.8 (even if the current Rancher version is 2.5.8), you will not be able to successfully deploy Monitoring V2 for Windows until you upgrade the wins version on each host to at least v0.1.0.
To facilitate this upgrade, Rancher 2.5.8 has released a brand new Helm chart called
Prerequisite: Make sure Monitoring V1 for Windows is uninstalled.

# Masquerading bootstraps the wins-upgrader installation via
# a previously whitelisted process path since the normal install path,
# c:\etc\rancher\wins\wins-upgrade.exe is not normally whitelisted.
# In this case, we are using the previously whitelisted process
# path used by Monitoring V1.

If you set up the RKE cluster with a

win_prefix_path, you will need to update the
masquerade.asfield with your prefix path in place of
For example, if you have
win_prefix_path: 'c:\host\opt\', then you will need to set
Once all your hosts have been successfully upgraded, please ensure that you deploy the Helm chart once again with default values to avoid conflicts with the following settings:
Result: The hosts are ready for Monitoring V2 to be installed. You may choose to uninstall the
rancher-wins-upgrader chart or keep it in your cluster to facilitate future upgrades.
