Description

Collect data from WMI query

This is useful for collecting performance metrics and other data which is accessible via WMI on a Windows host

Example:

    input {
      wmi {
        query => "select * from Win32_Process"
        interval => 10
      }
      wmi {
        query => "select PercentProcessorTime from Win32_PerfFormattedData_PerfOS_Processor where name = '_Total'"
      }
      wmi { # Connect to a remote host
        query => "select * from Win32_Process"
        host => "MyRemoteHost"
        user => "mydomain\myuser"
        password => "Password"
      }
    }

Details

edit

 

add_field

edit
  • Value type is hash
  • Default value is {}

Add a field to an event

codec

edit
  • Value type is codec
  • Default value is "plain"

The codec used for input data. Input codecs are a convenient method for decoding your data before it enters the input, without needing a separate filter in your Logstash pipeline.

enable_metric

edit
  • Value type is boolean
  • Default value is true

Disable or enable metric logging for this specific plugin instance by default we record all the metrics we can, but you can disable metrics collection for a specific plugin.

  • Value type is string
  • There is no default value for this setting.

Add a unique ID to the plugin configuration. If no ID is specified, Logstash will generate one. It is strongly recommended to set this ID in your configuration. This is particularly useful when you have two or more plugins of the same type, for example, if you have 2 wmi inputs. Adding a named ID in this case will help in monitoring Logstash when using the monitoring APIs.

input {
  wmi {
    id => "my_plugin_id"
  }
}

tags

edit
  • Value type is array
  • There is no default value for this setting.

Add any number of arbitrary tags to your event.

This can help with processing later.

type

edit
  • Value type is string
  • There is no default value for this setting.

Add a type field to all events handled by this input.

Types are used mainly for filter activation.

The type is stored as part of the event itself, so you can also use the type to search for it in Kibana.

If you try to set a type on an event that already has one (for example when you send an event from a shipper to an indexer) then a new input will not override the existing type. A type set at the shipper stays with that event for its life even when sent to another Logstash server.
