Upgrade Assistant - Critical Errors!


We are trying to upgrade our ELK from 7.17 to 8.6 using upgrade Assistant.
It is showing critical alert in Kibana and as follows:-

Configuring the "container ID" field has been deprecated and will be removed in 8.0.0. This plugin is designed to work with ECS, and expects this field to have a value of container.id. It has a different value configured in Source Configuration: Default

How to fix (provided by Upgrade assistant)

Adjust your indexing to identify Docker containers using "container.id".

I tried to check my indices and saw we are using "container.id" only.

Any help would be much appreciated

Issue resolved

Observability --> Metrics ---> settings ----> change the docker.container.id to container.id

If you are getting same error for host.name do the same.

Observability --> Metrics ---> settings ----> change the host to host.name
