syslog input to retain source hostname about fluentd-docker-image HOT 6 CLOSED

See: http://docs.fluentd.org/v0.12/articles/in_syslog#sourcehostnamekey

from fluentd-docker-image.

I tried adding source_hostname_key, but still I get the fluentd container hostname in the source field:

<source>
 @type syslog
 port 514
 tag syslog
 source_hostname_key
</source>

Also facility keeps being "fluentd" instead of the origin facility.
Tag is switching between "syslog.facility.level" and "fluent.warn"
I guess I have to do some reformatting/filtering, but to do that I have to have a unique pattern to match from

from fluentd-docker-image.

source_hostname_key

Why empty? Need key name. See document again.

from fluentd-docker-image.

And maybe, use_record_host parameter is needed: https://github.com/emsearcy/fluent-plugin-gelf/blob/master/lib/fluent/plugin/out_gelf.rb#L7

from fluentd-docker-image.

thanks for your answers ..
I read the docs more than twice on this part, but I don't get it gramatically:

 If set the value

which value?
I understand that I have to set a static value like "webserver01" ...
But I have tons of servers sending their logs to fluent on port 514.

I tried to set both options to "true":

<source>
 @type syslog
 port 1514
 tag syslog
 source_hostname_key true
 use_record_host true
</source>

But still nothing changes. "source" is always the hostname of the fluentd docker container

from fluentd-docker-image.

The entire explanation is "The field name of the client’s hostname. If set the value, the client’s hostname will be set to its key. The default is nil (no adding hostname)."

the value -> The field name of the client’s hostname -> source_hostname_key

use_record_host true

This is gelf plugin, not syslog plugin. See my comment again: #89 (comment)

How about source_hostname_key host and use_record_host true?
