Problem MySQL mariadb

Hello, I am having problems in the database, the panel gives me very high peaks, in these captures perhaps little can be seen but I have peaks of 40%, even more than 100%, I only have 2 pages without many daily users, how can I log in this and know what is happening?

Check the access logs and see why there is a peak off traffic

I do not get anything in that file, I am also observing these CPU spikes that I think are not normal either

2 out of 4 screenshots show an high CPU usage due to FFMPEG
