Why is the timestamp used in the managed configuration index in kibana not always available?

Data must be manually added from logstash before it can be used.

At this time, look at the create in

Configure an index pattern

and you can use it.

And
the index name or pattern is
logstash-*

index contains time-based events.

time-field name: @timestamp is

finally available.

If you just simply add a few records in ES. This CREATE is unavailable.

A big circle. There is a sentence that should not be said. Fucking MMP.....
