## Installation
The latest release can be downloaded from the [releases page](https://github.com/martinlindhe/wmi_exporter/releases).

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`

Parameters are sent to the installer via `msiexec`. Example invocation:

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

## Usage

    go get -u github.com/kardianos/govendor
    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](http://localhost:9182)

## Examples

Please note: The quotes in the parameter names are required because of how Powershell parses command line arguments.

### Enable only service collector and specify a custom query

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


## Examples

Please note: The quotes in the parameter names are required because of how Powershell parses command line arguments.

### Enable only process collector and specify a custom query

    .\wmi_exporter.exe "-collectors.enabled" "process" "-collector.process.processes-where" "Name='firefox'"
