Installation

The latest release can be downloaded from the releases page.

Each release provides a .msi installer. The installer will setup the WMI 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
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\wmi_exporter.msi ENABLED_COLLECTORS="ad,iis,logon,memory,process,tcp,thermalzone" TEXTFILE_DIR="C:\custom_metrics\"

Usage

go get -u github.com/golang/dep
go get -u github.com/prometheus/promu
go get -u github.com/martinlindhe/wmi_exporter
cd $env:GOPATH/src/github.com/martinlindhe/wmi_exporter
promu build -v .
.\wmi_exporter.exe

The prometheus metrics will be exposed on localhost:9182

Examples

Enable only service collector and specify a custom query

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

Enable only process collector and specify a custom query

.\wmi_exporter.exe --collectors.enabled "process" --collector.process.processes-where "Name LIKE '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 query needs to be a wildcard search using a % character.

Please note that in Windows batch scripts (and when using the cmd command prompt), the % character is reserved, so it has to be escaped with another %. For example, the wildcard syntax for searching for all firefox processes is firefox%%.
