`prometheus.exporter.windows`

The prometheus.exporter.windows component embeds the windows_exporter which exposes a wide variety of hardware and OS metrics for Windows-based systems.

The windows_exporter itself comprises various collectors, which you can enable and disable as needed. For more information on collectors, refer to the collectors-list section.

Note
The blacklist and whitelist configuration arguments are available for backwards compatibility but are deprecated. The include and exclude arguments are preferred going forward.

Usage

prometheus.exporter.windows "<LABEL>" {
}

While there are ways to construct this directly in Alloy syntax using raw Alloy syntax strings for example, the best way to configure this collector will be using a local.file component.

local.file "counters" {
  filename = "/etc/alloy/performance_counters.yaml"

User-supplied exclude and include strings are wrapped in a regular expression.

`tcp`

Name	Type	Description	Default	Required

`text_file`

Name	Type	Description	Default	Required
`text_file_directory`	`string`	The directory containing the files to be ingested.	see below	no

The default value for text_file_directory is relative to the location of the Alloy executable. By default, text_file_directory is set to the textfile_inputs directory in the installation directory of Alloy. For example, if Alloy is installed in C:\Program Files\GrafanaLabs\Alloy\, the default is C:\Program Files\GrafanaLabs\Alloy\textfile_inputs.

When text_file_directory is set, only files with the extension .prom inside the specified directory are read.

Note
The .prom files must end with an empty line feed for the component to recognize and read them.

Exported fields

The following fields are exported and can be referenced by other components.

Name	Type	Description
`targets`	`list(map(string))`	The targets that can be used to collect exporter metrics.

For example, the targets can either be passed to a discovery.relabel component to rewrite the targets’ label sets or to a prometheus.scrape component that collects the exposed metrics.

The exported targets use the configured in-memory traffic address specified by the run command.

Component health

prometheus.exporter.windows is only reported as unhealthy if given an invalid configuration. In those cases, exported fields retain their last healthy values.

Debug information

prometheus.exporter.windows doesn’t expose any component-specific debug information.

Debug metrics

prometheus.exporter.windows doesn’t expose any component-specific debug metrics.

Wrap regular expression strings

Some collector blocks such as scheduled_task accept a regular expression as a string argument. prometheus.exporter.windows prefixes some regular expression string arguments with ^(?: and suffixes them with )$. For example, if a user sets an exclude argument to ".*", Alloy sets it to "^(?:.*)$".

To find out if a particular regular expression argument will be wrapped, refer to the collector block documentation.

Note
The wrapping may change the behaviour of your regular expression. For example, the e.* regular expression would normally match both the “service” and “email” strings. However, ^(?:e.*)$ would only match “email”.

Collectors list

The following table lists the available collectors in windows_exporter. Some collectors only work on specific operating systems, enabling a collector that’s not supported by the host OS where Alloy is running is a no-op.

Users can choose to enable a subset of collectors to limit the amount of metrics exposed by the prometheus.exporter.windows component, or disable collectors that are expensive to run.

Refer to the linked documentation on each collector for more information on reported metrics, configuration settings and usage examples.

Caution
Certain collectors cause Alloy to crash if those collectors are used and the required infrastructure isn’t installed. These include but aren’t limited to mscluster, vmware, nps, dns, msmq, ad, hyperv, and scheduled_task.
The cs collector has been deprecated and may be removed in future versions of the exporter.

Example

The following example uses a prometheus.scrape component to collect metrics from prometheus.exporter.windows:

prometheus.exporter.windows "default" { }

// Configure a prometheus.scrape component to collect windows metrics.
prometheus.scrape "example" {
  targets    = prometheus.exporter.windows.default.targets
  forward_to = [prometheus.remote_write.demo.receiver]
}

prometheus.remote_write "demo" {
  endpoint {
    url = "<PROMETHEUS_REMOTE_WRITE_URL>"

    basic_auth {
      username = "<USERNAME>"
      password = "<PASSWORD>"
    }
  }
}

Replace the following:

<PROMETHEUS_REMOTE_WRITE_URL>: The URL of the Prometheus remote_write compatible server to send metrics to.
<USERNAME>: The username to use for authentication to the remote_write API.
<PASSWORD>: The password to use for authentication to the remote_write API.
