Log retention query

Good morning everyone,

Before I get on with today's problem, I would like to say how much I
appreciate this community and everything that you do for end users.

In today's problem I would like to understand if the following lines in our
config handle the log rotation for our clusters?

        log_checkpoints: on
        logging_collector: on
        log_truncate_on_rotation: on
        log_rotation_age: 1d
        log_rotation_size: 1GB
        log_error_verbosity: verbose

I have been deleting the logs manually for the last month, since I am
confused how the log collector rotates them.

Am looking to delete logs older than 180 days. What are we doing wrong in
the config?
