What is Maria Cluster?

A MariaDB Cluster (commonly implemented using Galera Cluster) is a synchronous multi-master database system where multiple MariaDB servers, called nodes, operate as a single logical database. Each node can process both read and write operations, and all committed transactions are automatically replicated across every node to maintain real-time consistency. This architecture ensures high availability, as applications can continue to function even if one node fails. It also provides fault tolerance and supports scalability, allowing organizations to handle larger workloads. MariaDB Cluster is widely used in mission-critical environments where data integrity and continuous service are crucial.

Why Monitor Maria Cluster?

A MariaDB Cluster is a synchronous multi-master database system that provides high availability, scalability, and real-time data consistency. Organizations prefer this setup because it allows applications to continue running even if one node fails, and it supports seamless horizontal scaling for growing workloads. However, administrators often face challenges such as node crashes, replication delays, quorum loss, data inconsistency, and resource bottlenecks. Monitoring helps detect these issues early, ensures cluster health and performance, and enables proactive actions to avoid downtime and maintain service reliability.

The eG Enterprise monitoring model for Maria Cluster offers a unique, end-to-end approach by automatically discovering cluster nodes, tracking replication status, monitoring resource utilization, and alerting on anomalies in real time. This ensures IT teams gain deep visibility into database health, user experience, and backend infrastructure dependencies, enabling them to troubleshoot faster and guarantee uninterrupted service delivery.
