Hi, i have logs in Json format stored in Elasticsearch and i want to create a custom bar chart using Lens, but i don't know how to access all the data inside the logs, the only values that i can use to make the chart is the _message.keyword_ and the _timestamp.keyword_. how can i use other values like Level of the logfile (Info, trace, debug) or State (Successful, Error, Executing)?. Thanks in advance. ---

Hi, I'm one of the engineers who works on Lens. Based on your description of the log data, I would not expect there to be any issues. So to find issues, can you provide an idea of: a) What does a sample document look like? b) What does your index pattern management screen look like? This will help me understand whether your data is structured in a way that we expect. ---

Okay, it looks like your index pattern object in Kibana is outdated. Please try the refresh button in the top right of the screen, which will load the new mappings. ---
