Implement end-to-end integration tests for MySQL database insights, mirroring the existing PostgreSQL DBI test in test/otel_collect/database_insights. - Setup script installs MySQL across yum/apt/zypper, enables performance_schema with statement/wait consumers, configures the error log, and creates a cw_monitor user (SELECT on performance_schema, PROCESS, REPLICATION CLIENT) plus a sysbench workload user - Agent config targets localhost:3306 with a pgpass-style passfile - Workload generation via sysbench oltp_read_write (mysqlslap fallback) - Validates counter metrics (enabled-by-default receiver metrics only), the 7 DB Load metrics, and Top SQL metrics via PromQL with resource attribute labels (db.system.name=mysql, db.instance.name) - Validates mysqld process metrics from the host metrics process scraper - Validates server logs and raw events in CloudWatch Logs, including db.server.top_query event attributes - Register in test case generator with ol8/ubuntu-25 exclusions and exclude from ARM64 itar/china partitions (same as PostgreSQL DBI tests)
