prometheus.exporter.windows

The prometheus.exporter.windows component embeds 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 black and white list configuration options are available for backwards compatibility but are deprecated. The include and exclude configuration options are preferred going forward.

Usage

river
prometheus.exporter.windows "LABEL" {
}

Arguments

The following arguments can be used to configure the exporter’s behavior. All arguments are optional. Omitted fields take their default values.

NameTypeDescriptionDefaultRequired
enabled_collectorslist(string)List of collectors to enable.["cpu","cs","logical_disk","net","os","service","system"]no
timeoutdurationConfigure timeout for collecting metrics.4mno

enabled_collectors defines a hand-picked list of enabled-by-default collectors. If set, anything not provided in that list is disabled by default. Refer to the Collectors list for the default set.

Specifying enabled_classes is useful to limit the response to the MSMQs you specify, reducing the size of the response.

mssql block

NameTypeDescriptionDefaultRequired

NIC names must match the regular expression specified by include and must not match the regular expression specified by exclude to be included.

process block

NameTypeDescriptionDefaultRequired
excludestringRegular expression of processes to exclude.""no
includestringRegular expression of processes to include.".*"no

Processes must match the regular expression specified by include and must not match the regular expression specified by exclude to be included.

scheduled_task block

NameTypeDescriptionDefaultRequired
excludestringRegexp of tasks to exclude.""no
includestringRegexp of tasks to include.".+"no

For a server name to be included, it must match the regular expression specified by include and must not match the regular expression specified by exclude.

service block

NameTypeDescriptionDefaultRequired
use_apistringUse API calls to collect service data instead of WMI.falseno
where_clausestringWQL ‘where’ clause to use in WMI metrics query.""no

The where_clause argument can be used to limit the response to the services you specify, reducing the size of the response. If use_api is enabled, ‘where_clause’ won’t be effective.

smtp block

NameTypeDescriptionDefaultRequired
excludestringRegexp of virtual servers to ignore.no
includestringRegexp of virtual servers to include.".+"no

For a server name to be included, it must match the regular expression specified by include and must not match the regular expression specified by exclude.

text_file block

NameTypeDescriptionDefaultRequired
text_file_directorystringThe directory containing the files to be ingested.C:\Program Files\Grafana Agent Flow\textfile_inputsno

When text_file_directory is set, only files with the extension .prom inside the specified directory are read. Each .prom file found must end with an empty line feed to work properly.

Exported fields

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

NameTypeDescription
targetslist(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 does not expose any component-specific debug information.

Debug metrics

prometheus.exporter.windows does not expose any component-specific debug metrics.

Collectors list

The following table lists the available collectors that windows_exporter brings bundled in. Some collectors only work on specific operating systems; enabling a collector that is not supported by the host OS where Flow 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.

Caution

Certain collectors will cause Grafana Agent 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, teradici_pcoip, ad, hyperv, and scheduled_task.

Example

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

river
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.

prometheus.exporter.windows has exports that can be consumed by the following components:
