Windows Exporter Metrics

A plugin based on Prometheus Windows Exporter to collect system / host level metrics

Prometheus Windows Exporter is a popular way to collect system level metrics from microsoft windows, such as CPU / Disk / Network / Process statistics. Fluent Bit 1.9.0 includes windows exporter metrics plugin that builds off the Prometheus design to collect system level metrics without having to manage two separate processes or agents.

The initial release of Windows Exporter Metrics contains a single collector available from Prometheus Windows Exporter and we plan to expand it over time.

Important note: Metrics collected with Windows Exporter Metrics flow through a separate pipeline from logs and current filters do not operate on top of metrics.

Configuration

Description

Default

Collectors available

The following table describes the available collectors as part of this plugin. All of them are enabled by default and respects the original metrics name, descriptions, and types from Prometheus Windows Exporter, so you can use your current dashboards without any compatibility problem.

note: the Version column specifies the Fluent Bit version where the collector is available.

Getting Started

Simple Configuration File

In the following configuration file, the input plugin _windows_exporter_metrics collects _metrics every 2 seconds and exposes them through our Prometheus Exporter output plugin on HTTP/TCP port 2021.

# Node Exporter Metrics + Prometheus Exporter
# -------------------------------------------
# The following example collect host metrics on Linux and expose
# them through a Prometheus HTTP end-point.
#
# After starting the service try it with:
#
# $ curl http://127.0.0.1:2021/metrics
#
[SERVICE]
    flush           1
    log_level       info

[INPUT]
    name            windows_exporter_metrics
    tag             node_metrics
    scrape_interval 2

[OUTPUT]
    name            prometheus_exporter
    match           node_metrics
    host            0.0.0.0
    port            2021

You can test the expose of the metrics by using curl:

curl http://127.0.0.1:2021/metrics

Service where clause

Windows service collector will retrieve all of the service information for the local node or container. we.service.where, we.service.include, and we.service.exclude can be used to filter the service metrics.

To filter these metrics, users should specify a WHERE clause. This syntax is defined in the WMI Query Language(WQL).

Here is how these parameters should work:

we.service.where

we.service.where is handled as a raw WHERE clause. For example, when a user specifies the parameter as follows:

we.service.where Status!='OK'

This creates a WMI query like so:

SELECT * FROM Win32_Service WHERE Status!='OK'

The WMI mechanism will then handle it and return the information which has a "not OK" status in this example.

we.service.include

When defined, the we.service.include is interpreted into a WHERE clause. If multiple key-value pairs are specified, the values will be concatenated with OR. Also, if the values contain % character then a LIKE operator will be used in the clause instead of the = operator. When a user specifies the parameter as follows:

we.service.include {"Name":"docker","Name":"%Svc%", "Name":"%Service"}

The parameter will be interpreted as:

(Name='docker' OR Name LIKE '%Svc%' OR Name LIKE '%Service')

The WMI query will be called with the translated parameter as:

SELECT * FROM Win32_Service WHERE (Name='docker' OR Name LIKE '%Svc%' OR Name LIKE '%Service')

we.service.exclude

When defined, the we.service.exclude is interpreted into a WHERE clause. If multiple key-value pairs are specified, the values will be concatenated with AND.

Also, if the values contain % character then a LIKE operator will be used in the translated clause instead of the != operator. When a user specifies the parameter as follows:

we.service.exclude {"Name":"UdkUserSvc%","Name":"webthreatdefusersvc%","Name":"XboxNetApiSvc"}

The parameter will be interpreted as:

(NOT Name LIKE 'UdkUserSvc%' AND NOT Name LIKE 'webthreatdefusersvc%' AND Name!='XboxNetApiSvc')

The WMI query will be called with the translated parameter as:

SELECT * FROM Win32_Service WHERE (NOT Name LIKE 'UdkUserSvc%' AND NOT Name LIKE 'webthreatdefusersvc%' AND Name!='XboxNetApiSvc')

Advanced usage

we.service.where, we.service.include, and we.service.exclude can all be used at the same time subject to the following rules.

we.service.include translated and applied into the where clause in the service collector
we.service.exclude translated and applied into the where clause in the service collector
1. If the we.service.include is applied, translated we.service.include and we.service.exclude conditions are concatenated with AND.
we.service.where is just handled as-is into the where clause in the service collector .
1. If either of the above parameters is applied, the clause will be applied with AND ( the value of we.service.where ).

For example, when a user specifies the parameter as follows:

we.service.include {"Name":"docker","Name":"%Svc%", "Name":"%Service"}
we.service.exclude {"Name":"UdkUserSvc%","Name":"XboxNetApiSvc"}
we.service.where NOT Name LIKE 'webthreatdefusersvc%'

The WMI query will be called with the translated parameter as:

 SELECT * FROM Win32_Service WHERE (Name='docker' OR Name LIKE '%Svc%' OR Name LIKE '%Service') AND (NOT Name LIKE 'UdkUserSvc%' AND Name!='XboxNetApiSvc') AND (NOT Name LIKE 'webthreatdefusersvc%')

Enhancement Requests

Our current plugin implements a sub-set of the available collectors in the original Prometheus Windows Exporter, if you would like that we prioritize a specific collector please open a Github issue by using the following template: - in_windows_exporter_metrics
