Monitor ProxySQL with Datadog

ProxySQL is a MySQL/MariaDB protocol-compliant load balancer and reverse proxy that supports various backends like ClickHouse, Amazon Aurora, and Amazon RDS. It improves resource management and boosts database performance by efficiently distributing queries to servers and caching results. Datadog's integration with ProxySQL allows users to visualize, monitor, and alert on key metrics such as memory usage and query throughput. The integration also helps track the efficiency of ProxySQL's query cache, correlate cache reads and writes, ensure loads are balanced correctly, verify connections between clients and servers, and monitor the rate of slow queries.
