Frequent log in kibana 7.16.2

After upgrading Kibana 7.11.1 to 7.16.2, we are seeing continuous log in Kibana log file. Also, ES queries is being printed in log.

We are seeing such continuous log in Kibana 7.11.1 after successful startup.

But We are not seeing such behavior in Kibana 7.11.1 version.

Thank you inadvance

Hi @Suresh_Ghatuwa ,

Could you confirm that ES was upgraded successfully? All nodes are running as expected? What OS you are hosting at?
You should first upgrade it and make sure it is stable. Then you can proceed with Kibana upgrade.

We are seeing such continuous log in Kibana 7.11.1 after successful startup.
But We are not seeing such behavior in Kibana 7.11.1 version.

Could you clarify it: you saw this log on first restart, now it is gone and Kibana works fine?

Yes, ES 7.16.2 was installed successfully.
OS: CentOS (Hosted in AWS EC2)

WE upgraded Kibana only after ES upgrade completion. Also, we restarted Kibana multiple times but still showing continuous log.

In kibana 7.11. version, we are not seeing such logs for any cases on default settings.

@Suresh_Ghatuwa,

Can you check how many objects do you have in Kibana indexes, having too many could make migration complicated:

POST .kibana,.kibana_task_manager/_search?filter_path=aggregations
{
     "aggs": {
       "saved_object_type": {
         "terms": {"field": "type"}
       }
     }
}

Can you post more logs so we see what your Kibana logs after that last message Starting saved objects migrations

Regards, Dima

Is your problem that you're seeing a lot more logs than what you're expecting? From the logs you shared I can see a lot of debug level logs which would produce a large volume of logs.

Make sure that your logging configuration only logs on info level. If you get stuck, please share your kibana.yml
