I'm trying to group same errors on kibana with elk stack
however when I visualise data by Error not all errors are there I'm visualising data on err_message.keyword field.
What I noticed is that long strings are not there where small strings are there and can be grouped fine.
Is there some limit on .keyword field type sometimes err_message have like 400 chars here and can't be visualised.
When I click on add missing and group other values I can see the Other and Missing values in err_message.keyword
Can you tell me how can I resolve this issue?
What is the elasticsearch mapping for the field err_message.keyword? If elasticsearch created the field mapping by default then it will probably look something like the below and the keyword field is getting trimmed at 256 characters.
