I think kibana doesn't have any problem with reading the file as it is being
modified, because it would continually update when it was refreshed. That is
with rsyslog service off.
the only thing that could be different with the rsyslog service on is that the
file is held open. When you say that kibana is reading the file when it's
refreshed, is whatever is refreshing it keeping the file open and writing to it?
or is it opening the file, writing to the file, closing the file, at which
point kibana is reading the file.
I'm a little confused when you recommend using
omelasticsearch. I thought that module already gets loaded.
If you are having kibana read a file to get the data into elasticsearch, you
aren't using omelasticsearch
omelasticsearch does a http call to elasticsearch to send the data directly, it
doesn't write it to a file for another process to read.

David,
Ok figure this one out...So I completely deleted all my elasticsearch
coding in the rsyslog.conf file and went back to the default
rsyslog.conf file that you get in centos.
I get no failures on any of the actions. So I clear my debug and
rsyslogd.log files to start fresh.
I stop the rsyslog service. Run debug from the command line.
(/sbin/rsyslogd
-c3 -dn > /var/log/debug.log)
one thing, -c3 says to use the config language of version 3, it's not needed on
current versions (I don't remember when it was dropped, I think a lot of v5
stuff still needed at least -c4)
So it begins to debug. This continues to run so it fills my
rsyslogd.log file and kibana is picking up the logs from that file. So
I start the rsyslog service....which in turn kibana stops reading the logs.
Ok, it sounds as if there is locking going on, kibana doesn't want to read from
a file that may be modified as it's reading it. you could work around this by
rotating the file every minute. This is where omelasticsearch would be better.
So I add back in the first part of my config part for elasticsearch
and the same results happen. It still picks up the logs in the
rsyslogd.log file but nothing else. When I stop the rsyslog service
kibana picks up the logs and when I start the service it stops picking
up the logs. It only accounts for this one file. It won't read any other file.
is there a debug mode for kibana so it can tell you why it's not doing what you
expect it to?
David Lang
So I know fundamentally there is communication. Now my question is why
isn't it working when I start the rsyslog service? I've read 3-4
different tutorials on coding the rsyslog.conf file for elasticsearch
and they all have the same configuration.

action 11 is failing, unless it has a separate queue it can be causing you
significant other problems. I would suggest either commenting that out and
trying again, or looking into what is failing there.
using omelasticsearch is suggested because it results in the most direct
connection (allowing better detections of failures.

Well it looks like my celebrations for success was pre-mature.
Initially when I stated that it was working. It indexed 230 lines of
logs over to kibana. Now it isn't doing anything. I then started
researching to see what the issue is and I came across an article
that said in order to have rsyslog drop logs into elasticsearch you have to
have omelasticsearch. Is this true?
From other tutorials it shows to use omelasticsearch in the
rsyslog.conf, but I have never configured it. Maybe someone can help
me with my config. Here is the portion that I think should be going to
elasticsearch.

------ So after reviewing the debug file for the action 2, 3, and 11;
I couldn't find any errors at all. Most of the output shows it being processed.
Nothing indicates that there was a problem. I'm stuck...
