fluentd - Windows GELF plugin

[Stephen]

Hello,

I'm using the v0.14 experimental Windows fluentd MSI, following the instructions at http://docs.fluentd.org/v0.14/articles/install-by-msi

I'm trying to install/use the GELF plugin, to send logs to to Graylog2.


When I try and run fluentd (fluentd -c conf\td-agent.conf), I get the error
[error]: config error file="conf\\td-agent.conf" error_class=Fluent::ConfigError error="Unknown output plugin 'gelf'. Run 'gem search-rd fluent-plugin' to find plugins"


As stated in the documentation, I have attempted to install the plugin with 'fluent-gem install gelf', which says it successfully installs, but I get the same error when rerunning.

Am I missing something? Can anyone provide any assistance?

Many thanks,
Stephen


My td-agent.conf file
<source>
  type tail
  tag graylog2.test.app1
  path c:\testlogs\%Y-%m-%d.txt
  pos_file c:\testlogs\fluentd-test.log.pos
  format multiline
  format_firstline /^\[\d{2}\:\d{2}\:\d{2}/
  format1 /^\[(?<time>\d{2}\:\d{2}\:\d{2})\: (?<msgtype>.*)\]\: (?<message>.*)/
</source>

<match graylog2.**>
  type copy
  <store>
    type gelf
    host graylog.mydomain.net
    port 12201

Where to install fluent-plugin-gelf code?

I still don't fully understand why the plugin is not working/available when running a 'fluent-gem search gelf' and installing all gelf related plugins, but I manually downloaded the fluent-plugin-gelf plugin from https://github.com/emsearcy/fluent-plugin-gelf, and put it in C:\opt\td-agent\embedded\lib\ruby\gems\2.3.0\gems\fluent-plugin-gelf.

Then ran the following:
fluentd -c conf\td-agent.conf -p "C:\opt\td-agent\embedded\lib\ruby\gems\2.3.0\gems\fluent-plugin-gelf\lib\fluent\plugin"


It's now working and reporting logs back to Graylog as intended.

The problem is windows doesn't have unified directory structure.

On Linux, fluentd uses /etc/fluent and td-agent uses /etc/td-agent for configuration and plugin directory by default.

But windows doesn't have such directories, e.g. /etc, /var, /tmp.

If you use -p option, directory path has no limitation.

Downloading out_gelf.rb into `C:\opt\td-agent\plugin` and `-p C:\opt\td-agent\plugin` should work.

I want to know a good way for directory structure on Windows.
