Have very hard times to get Metricbeat mysql raw filtering working. The docs even state that "filters" are obsolete and will be replaced by a new mechanism. By which?
https://www.elastic.co/guide/en/beats/metricbeat/current/configuration-metricbeat.html

It seems the Metricbeat filtering stuff is not documented for mysql raw field usage. We tried all sorts of patterns, but it simply does not work.

In my case, I want to filter on Innodb buffer status, and already tried many patterns, but none of them worked:

• mysql.status.raw.Innodb_buffer_pool_pages_flushed
• Innodb_buffer_pool_pages_flushed
• status.raw.Innodb_buffer_pool_pages_flushed
• raw.Innodb_buffer_pool_pages_flushed
• mysql.status.raw.Innodb.buffer.pool.pages.flushed

.. and so on.

I even didn't find any examples on GH in any project how to filter on mysql raw status values.
