Now it's a log4net appender to elastic that knows knows how to log web context and can format some stack traces.
Register it as an appender in log4net.
Parameters: connectionstring: Right now a connection string looking like a database connection string.
<appender name="ElasticSearchAppender" type="ElasticElmah.Appender.ElasticSearchAppender, ElasticElmah.Appender">
<connectionString value="Server=localhost;Index=log;Port=9200"/>
</appender>
In order to read logs, you can use the class ElasticSearchRepository. There is a test site based on Elmah (ElasticElmahMVC). The reason for an asp.net MVC site is that it enables you to integrate logging information with your admin site
Elmah has a dump of the web context. Implemented against log4net here ./src/ElasticElmah.Appender/ElasticSearchWebAppender.cs
Same as ELMAH
