Hi. I am trying to log to our ElasticSearch, but i get the following error:

log4net: Loading Appender [ElasticSearchAppender] type: [log4stash.ElasticSearchAppender, log4stash]
log4net: Setting Property [Server] to String value [192.168.240.199]

My config is as your example

192.168.240.199
9200

what could be?

Please attach the complete configuration in order for us to be able to help you

In addition, please specify:

• log4stash version you use.
• Do you have access to the elasticsearch log files? if so, can you share the error that is written there?
• At last, please try setting SerializeObjects to false as you can see in the configuration example here and see if anything changes.

[gaguerre]

Log4Net Version 1.2.15.0
Log4Stash Version 2.0.0.0

SerializeObjects set to False but got same error

App.config.txt

ElasticSearch.log does not register new entries

[urielha]

I guess you are using ElasticSearch 6.0 RC 2?
Try to upgrade log4stash to 2.1.0 or higher .
You can read the release notes for each version here: Releases

Furthermore, because you are using version 2.0.0 there are few breaking changes you need to be aware of which are listed here: Breaking Changes
Edit: From your configuration it seems you don't have any updates to do (due to breaking changes)
