Windows Event Log (winevtlog)

The winevtlog input plugin allows you to read Windows Event Log with new API from winevt.h.

Configuration Parameters

The plugin supports the following configuration parameters:

Note that if you do not set db, the plugin will tail channels on each startup.

Configuration Examples

Configuration File

Here is a minimum configuration example.

[INPUT]
    Name         winevtlog
    Channels     Setup,Windows PowerShell
    Interval_Sec 1
    DB           winevtlog.sqlite

[OUTPUT]
    Name   stdout
    Match  *

Note that some Windows Event Log channels (like Security) requires an admin privilege for reading. In this case, you need to run fluent-bit as an administrator.

The default value of Read_Limit_Per_Cycle is set up as 512KiB. Note that 512KiB(= 0x7ffff = 512 * 1024 * 1024) does not equals to 512KB (= 512 * 1000 * 1000). To increase events per second on this plugin, specify larger value than 512KiB.

Query Languages for Event_Query Parameter

The Event_Query parameter can be used to specify the XML query for filtering Windows EventLog during collection. The supported query types are XPath and XML Query. For further details, please refer to the MSDN doc.

Command Line

If you want to do a quick test, you can run this plugin from the command line.

$ fluent-bit -i winevtlog -p 'channels=Setup' -p 'Read_Existing_Events=true' -o stdout

Note that winevtlog plugin will tail channels on each startup. If you want to confirm whether this plugin is working or not, you should specify -p 'Read_Existing_Events=true' parameter.
