recently I realized after I setup master to master replication using galera, my db seems to be loading slower than usual.
Also, sometimes it cannot be connected.
I am currently using django and I have it setup that if main DB cannot be connected while making a request, then use the second db until the main DB is back online. I will receive an email if the DB cannot be connected while making a request.
This would happen randomly and sometimes when I get the email, then right away I login into mariadb to check its status...it's actually actively running.
As for db seems to be loading slower than usual is because, when I go into the django admin dashboard, usually it just boom when I check any records or go into any model but now it'll LOAD...........then show.
I can barely find out any reason for this, does any one have any idea or which / where log I can setup for a more thorough check?
Thanks in advance for any advices.
