wmi

Milestone: 1

This is a community-contributed plugin! It does not ship with logstash by default, but it is easy to install! To use this, you must have installed the contrib plugins package.

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'"
  }
}

Synopsis

This is what it might look like in your config file: 
input {
  wmi {
    add_field => ... # hash (optional), default: {}
    codec => ... # codec (optional), default: "plain"
    interval => ... # number (optional), default: 10
    query => ... # string (required)
    tags => ... # array (optional)
    type => ... # string (optional)
  }
}

  • There is no default value for this setting.

The character encoding used in this input. Examples include “UTF-8” and “cp1252”

This setting is useful if your log files are in Latin-1 (aka cp1252) or in another character set other than UTF-8.

This only affects “plain” format logs since json is UTF-8 already.

codec

  • 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.

debug DEPRECATED

  • DEPRECATED WARNING: This config item is deprecated. It may be removed in a further version.
  • Value type is boolean
  • Default value is false

format DEPRECATED

  • DEPRECATED WARNING: This config item is deprecated. It may be removed in a further version.
  • Value can be any of: "plain", "json", "json_event", "msgpack_event"
  • There is no default value for this setting.

The format of input data (plain, json, json_event)

interval

  • Value type is number
  • Default value is 10

Polling interval

message_format DEPRECATED

  • DEPRECATED WARNING: This config item is deprecated. It may be removed in a further version.
  • Value type is string
  • There is no default value for this setting.

If format is “json”, an event sprintf string to build what the display @message should be given (defaults to the raw JSON). sprintf format strings look like %{fieldname}

If format is “json_event”, ALL fields except for @type are expected to be present. Not receiving all fields will cause unexpected results.

query (required setting)

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

WMI query

tags

  • 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

  • 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 the web interface.

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.
