Old .kibana indexes

Hello,

I've noticed we have kibana indexes:
.kibana-event-log-7.10.2-*
.kibana_*
.kibana_task_manager_*

And then since we upgraded to 7.13.1 we also have:
.kibana-event-log-7.13.1-*
.kibana_7.13.1_*
.kibana_task_manager_7.13.1_*

I was wondering if I can delete old .kibana indexes showed at the top?
These are mostly empty, but I can see that for example .kibana-event-log-7.10.2-* are still being created. How can I stop them?

Kind regards,
Dane

Hi
Could you share an example of the logs that are created in

.kibana-event-log-7.10.2-*

Are there logs in

.kibana-event-log-7.13.1-*

Are there multiple Kibana instances?

Thx!

Hi Matt,

Yes, there are two Kibana instances.

.kibana-event-log-7.10.2-* indexes are empty.
And here is a document from .kibana-event-log-7.13.1-* index:

      {
        "_index" : ".kibana-event-log-7.13.1-000001",

              }
            ],
            "alerting" : {
              "status" : "ok"
            },
            "server_uuid" : "cdbcbb2c-5105-493d-9767-9a8373fd043d"

Thanks for the help.

Kind regards,
