#Release 1.1 is live! Release Notes

How

Elmah.Io.ElasticSearch is configured pretty much like every other storage implementation for Elmah. To get started, add the following to your web.config:

<connectionStrings>
    <add name="ElmahIoElasticSearch" connectionString="http://localhost:9200/elmah"/>
</connectionStrings>

<elmah>
    <errorLog type="Elmah.Io.ElasticSearch.ElasticSearchErrorLog, Elmah.Io.ElasticSearch"
    connectionStringName="ElmahIoElasticSearch" />
</elmah>

Replace the connection string URL with your Elasticsearch URL and add the elmah config section as explained on the offical ELMAH site.

##Configuration

The Elasticsearch index name can be specified one of two ways, let's say you want the index name to be elmahCurrent:

1: Put it in the connection string (preferred)

<connectionStrings>
    <add name="ElmahIoElasticSearch" connectionString="http://localhost:9200/elmahCurrent"/>
</connectionStrings>

2: Leave it off the connection string and put it in the elmah specification

<connectionStrings>
    <add name="ElmahIoElasticSearch" connectionString="http://localhost:9200"/>
</connectionStrings>

<errorLog
    type="Elmah.Io.ElasticSearch.ElasticSearchErrorLog, Elmah.Io.ElasticSearch"
    connectionStringName="ElmahIoElasticSearch"
    defaultIndex="elmahCurrent" />

You can optionally specify the following fields that will be written to search:

1. Application Name
2. Environment Name
3. Customer Name

Specify these in the attribute:

  <elmah>
    <errorLog 
        type="Elmah.Io.ElasticSearch.ElasticSearchErrorLog, Elmah.Io.ElasticSearch, Version=1.0.0.0, Culture=neutral" 
        connectionStringName="ElmahElasticSearch" 
        applicationName="ElmahElasticSearchSampleWebsite"
        environmentName="development"
        customerName="sample customer"
        />
    <security allowRemoteAccess="false" />
  </elmah>

##Retreiving raw data To get the data from Elastic, run the following:

GET elmah/error/_search
{
  "query": {
    "match_all": {}
  }
}
