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

Filtering enabled collectors

The windows_exporter will expose all metrics from enabled collectors by default. This is the recommended way to collect metrics to avoid errors when comparing metrics of different families.

For advanced use the windows_exporter can be passed an optional list of collectors to filter metrics. The collect[] parameter may be used multiple times. In Prometheus configuration you can use this syntax under the scrape config.

  params:
    collect[]:
      - foo
      - bar

This can be useful for having different Prometheus servers collect specific metrics from nodes.

Flags

windows_exporter accepts flags to configure certain behaviours. The ones configuring the global behaviour of the exporter are listed below, while collector-specific ones are documented in the respective collector documentation above.

Flag Description Default value
--telemetry.addr host:port for exporter. :9182
--telemetry.path URL path for surfacing collected metrics. /metrics
--telemetry.max-requests Maximum number of concurrent requests. 0 to disable. 5
--collectors.enabled Comma-separated list of collectors to use. Use [defaults] as a placeholder for all the collectors enabled by default." [defaults]
--collectors.print If true, print available collectors and exit.
--scrape.timeout-margin Seconds to subtract from the timeout allowed by the client. Tune to allow for overhead or high loads. 0.5
--web.config.file A web config for setting up TLS and Auth None

Installation

The latest release can be downloaded from the releases page.

Each release provides a .msi installer. The installer will setup the windows_exporter as a Windows service, as well as create an exception in the Windows Firewall.

If the installer is run without any parameters, the exporter will run with default settings for enabled collectors, ports, etc. The following parameters are available:

Name Description
ENABLED_COLLECTORS As the --collectors.enabled flag, provide a comma-separated list of enabled collectors
LISTEN_ADDR The IP address to bind to. Defaults to 0.0.0.0
LISTEN_PORT The port to bind to. Defaults to 9182.
METRICS_PATH The path at which to serve metrics. Defaults to /metrics
TEXTFILE_DIR As the --collector.textfile.directory flag, provide a directory to read text files with metrics from
REMOTE_ADDR Allows setting comma separated remote IP addresses for the Windows Firewall exception (whitelist). Defaults to an empty string (any remote address).
EXTRA_FLAGS Allows passing full CLI flags. Defaults to an empty string.

Parameters are sent to the installer via msiexec. Example invocations:

msiexec /i <path-to-msi-file> ENABLED_COLLECTORS=os,iis LISTEN_PORT=5000

Example service collector with a custom query.

msiexec /i <path-to-msi-file> ENABLED_COLLECTORS=os,service --% EXTRA_FLAGS="--collector.service.services-where ""Name LIKE 'sql%'"""

On some older versions of Windows you may need to surround parameter values with double quotes to get the install command parsing properly:

msiexec /i C:\Users\Administrator\Downloads\windows_exporter.msi ENABLED_COLLECTORS="ad,iis,logon,memory,process,tcp,thermalzone" TEXTFILE_DIR="C:\custom_metrics\"

Supported versions

windows_exporter supports Windows Server versions 2008R2 and later, and desktop Windows version 7 and later.

Usage

go get -u github.com/prometheus/promu
go get -u github.com/prometheus-community/windows_exporter
cd $env:GOPATH/src/github.com/prometheus-community/windows_exporter
promu build -v
.\windows_exporter.exe

The prometheus metrics will be exposed on localhost:9182

Examples

Enable only service collector and specify a custom query

.\windows_exporter.exe --collectors.enabled "service" --collector.service.services-where "Name='windows_exporter'"

Enable only process collector and specify a custom query

.\windows_exporter.exe --collectors.enabled "process" --collector.process.whitelist="firefox.+"

When there are multiple processes with the same name, WMI represents those after the first instance as process-name#index. So to get them all, rather than just the first one, the regular expression must use .+. See process for more information.

Using a configuration file

YAML configuration files can be specified with the --config.file flag. E.G. .\windows_exporter.exe --config.file=config.yml

collectors:
  enabled: cpu,cs,net,service
collector:
  service:
    services-where: "Name='windows_exporter'"
log:
  level: warn

An example configuration file can be found here.

Configuration file notes

Configuration file values can be mixed with CLI flags. E.G.

.\windows_exporter.exe --collectors.enabled=cpu,logon

log:
  level: debug

CLI flags enjoy a higher priority over values specified in the configuration file.
