from a firewall I send log information to filebeat into a self written module. Within a kibana dashboard I have several lenses to get information of different events and aggregations. This is now running several days without any modification, no updates and no reboot. Today I realised that kibana doesn't show some data and brings an error. For example "Field mikrotik_remoteip is of the wrong type".
Using "Discover" I see an exclamation mark beside several fields, also for "mikrotik_remoteip". It says "This field is defined as several types ...."
When I visit "Stack Management" -> "Data Views" -> "filebeat-*" I also get the warning with details:
This field has a type conflict The type of the mikrotik_remoteip field changes across indices and might not be available for search, visualizations, and other analysis. Demo of EuiBasicTable Type Indices ip .ds-filebeat-8.3.2-2022.12.04-000001, .ds-filebeat-8.5.3-2022.12.11-000001 keyword .ds-filebeat-8.5.3-2023.01.10-000002
How is it that the type currently changed from "ip" to "keyword" ?
And what should be done that it doesn't happen again ?
Any help is welcome.
