Remove kibana deprecation warnings

[Usman18 (Usman Sajid)]

I am trying to remove kibana deprecation warnings. I am using kibana 7.10.2. There were some configurations that have been deprecated and I fixed those warnings. There is another deprecation warning that is still appearing. I do not have an idea how to fix this or is there any need to fix that deprecation warning? The logs of that deprecation warning are given below:

{"type":"log","@timestamp":"2022-02-03T22:39:34Z","tags":["warning","config","deprecation"],"pid":8,"message":"Config key [monitoring.cluster_alerts.email_notifications.email_address] will be required for email notifications to work in 8.0.\""}

Can anyone guide me how to fix this deprecation warning?

Here is the docs page for Kibana Monitoring settings.

Kibana is logging this warning because you have Cluster Alert Email Notifications enabled (by default) but you don't have an email address configured.

You can make this deprecation warning go away by doing one of two things:

1. Add an email address: monitoring.cluster_alerts.email_notifications.email_address: 'some-address@some-company.com', or
2. Disable email notifications if you don't need them: monitoring.cluster_alerts.email_notifications.enabled: false

It looks like our docs don't mention the second setting at all, I'll get in touch with the folks who own those docs, sorry about that!
