After running the API, Analytics will be displayed, but after a while the data will disappear.
01. Do "Publish APIs with the API Proxy and Policy Manager"
02. Do "Enable Analytics for Gateway-Published APIs"
03. After that, do the API.
04. Show Menu of Portal -> "Monitor" -> "Traffic,Latency&Errors Reposrt"
Result: The API graph is displayed.
05. After a few hours, go back to the "Traffic, Latency & Errors
Result: "No data" is displayed.
Also, The following phenomena are occurring.
. When you do "docker service ls", REPLICAS of portal_minio becomes 0/1.
. When "docker servle ps portal_minio" is done, the state is as follows
DESIRED STATE: Shutdown
CURRENT STATE: Complete
. Because of the above state, I performed "docker service update" referring to the following manual, but REPLICAS becomes 1/1 once, but after a while it returns to 0/1.

MinIO system is part of the analytics engine, the Druid system uses it to store data. (you can check the API Portal Architecture in the 4.5 document)
So the root cause of the problem -- if MinIO is down, the Druid has no data to show, we need to fix the portal_minio.
Release : 4.5
Component : API PORTAL
It seems to be an know issue and due to the healthcheck,
The workaround is to disable the portal_minio service.
The following command can be disable healthcheck for portal_minio service,
docker service update --no-healthcheck portal_minio
The command requires API version 1.25 or above, run "docker version" command to check API version. If the docker version is too low, then to upgrade docker first.
