Bug with Mariadb innodb_buffer_pool_reads counter

Hello,

I recently found out with my matomo application (5.3), that on my database Mariadb (10.11.6), no reads are being done on my innodb, but are rather being done on disc :

MariaDB [(none)]> show global status like 'innodb_buffer_pool_read%';~
-------------------------------------------------+

-------------------------------------------------+

-------------------------------------------------+
5 rows in set (0,000 sec)

Important note:

1. All tables in matomo are innodb engine (not MyISAM)
2. The database is up for 133 days, so the statistics of the innodb_buffer_pool_% are reliable.
3. My Innodb_buffer_pool_size is 10Gb

Thank you in advance for clarifying this.

Regards,
