[haoma2514]

Elastic.Clients.Elasticsearch version:8.17.1

Elasticsearch version:8.17.2

.NET runtime version:8.0

Operating system version:Windows 10 21H2

Description of the problem including expected versus actual behavior:
A clear and concise description of what the bug is.

Steps to reproduce:
1.

3.Log mapping to an object contains the Level attribute, but it becomes the "Log.Level" attribute after being obtained by the client.

Expected behavior
"level" is a property of the log object

Hi @haoma2514,

how do you ingest the logs?

The client does not modify the ingested documents/logs in any way. You always get exactly what's stored.

This means you have to address this issue on whatever place you use to ingest the logs.

FYI: The log.level and log: { level: ... } representation is equivalent for Elasticsearch given your current mapping. Processing, querying, etc. will work as expected.

The raw document however is not modified. If you need the property expanded in your .NET application, you have to make sure it's stored in the correct format in the first place (or you implement a custom JsonConverter for your log type and use that for deserialization).

Thank you for your reply. The log is written through Elastic.Extensions.Logging, for example: builder.logging.addelasticsearch (); I don't have a custom mapping relationship or an index template. Could it be Elastic.Extensions.Logging? In addition, I would like to ask, where can I quickly learn the client usage of V8 version?

[flobernd]

Yes, in this case it seems to be the way how Elastic.Extensions.Logging ingests the logs. If you need to expand this dot-notation, you must write your own JsonConverter for the log type.

The official documentation for the client is here: https://www.elastic.co/guide/en/elasticsearch/client/net-api/current/introduction.html. Improving it with more examples is something that's being worked on.

Please let me know, if you have more questions.
