Support for performance_metrics in mariadb

[barrypitman]

^^ I'm running into an error after enabling performance metrics for mariadb 10.3 ^^

Description

I'm running MariaDB on RHEL 8 - mysql Ver 15.1 Distrib 10.3.39-MariaDB, for Linux (x86_64) using readline 5.1

In my newrelic-mysql.yml file, I added ENABLE_QUERY_MONITORING: true, and added performance_schema=ON to my.cnf and restarted service newrelic-infra restart

When I run:

sudo /usr/bin/newrelic-infra -dry_run -integration_config_path /etc/newrelic-infra/integrations.d/mysql-config.yml

I get these errors (amongst other output):

time="2025-10-13T09:17:23+02:00" level=error msg="integration log" component=integration-errors env=production fields.level=error fields.msg="Error collecting blocking session metrics: Error 1146 (42S02): Table 'performance_schema.data_lock_waits' doesn't exist" integration_name=nri-mysql role=write-replica runner_uid=848a7516b8

time="2025-10-13T09:17:23+02:00" level=error msg="integration log" component=integration-errors env=production fields.level=error fields.msg="Failed to collect slow query metrics: Error 1054 (42S22): Unknown column 'SUM_CPU_TIME' in 'field list'" integration_name=nri-mysql role=write-replica runner_uid=848a7516b8

In my New Relic web portal, I'm not seeing anything related to the performance_schema, though I do see other info, e.g. innodb metrics.

Expected Behavior

I was hoping that the nri-mysql plugin would be able to monitor mariadb as well.
