In this blog, we will show you how to monitor Galera Cluster for MySQL or MariaDB using Prometheus. We will have a look at the newly released SCUMM architecture for agent-based monitoring and how ClusterControl deploys Prometheus and exporters to collect database metrics and the graphs available in the different dashboards.
The idea behind ClusterControl operational reporting is to put all of the most relevant data into a single document which can be quickly analyzed in order to get a clear understanding of the status of the databases and its processes. This blog post shows how to leverage the ops report functionality to understand the state of your MySQL, MariaDB, MongoDB and PostgreSQL infrastructure.
This blog post shows how to leverage ClusterControl performance monitoring and advisors functionality to keep your MySQL, MongoDB and/or PostgreSQL databases and clusters healthy.
ClusterControl can be used to deploy open-source database clusters that are configured in complex topologies. The full high availability stack includes both database and proxy layers.
In this blog, we are going to show you how to deploy a production-grade Galera Cluster, complete with load balancers, for a high availability setup.
In this blog post, we will show you how you can monitoring your database clusters using your terminal and the s9s Command Line Interface.
Prometheus is an open-source software for monitoring and alerting, it depends on exporters to ‘scrape’ information from e.g., MySQL running on Docker. In this blog, we’ll see how to deploy the database as well as the monitoring stack with Prometheus and its components. We’ll do this for both MySQL running on standalone Docker containers as well as a Galera Cluster running on Docker Swarm.
Asynchronous replication places no low latency demands on the network, so it is possible to keep Galera Clusters in sync even when they are thousands of miles apart and utilise low-cost connections. We effectively can achieve a global system of loosely-coupled clusters. However, managing the global state translates into managing failover and failback operations at both node and cluster level.
Galera automatic node provisioning and membership control simplifies database cluster operation and improves the reliability of its replication technology. In this blog post, we are diving into the Galera recovery process in events where network partitioning happens.
Galera Cluster comes with many cool features and advantages over traditional asynchronous replication, but these do not automatically translate into higher performance. In this blog post, we will look at what drives MySQL/MariaDB Galera performance, and see how we can get the most out of the cluster.
So you’ve deployed MariaDB cluster on Docker, what next? What do you do when containers fail or are rescheduled, and IP addresses change? How do you ensure that the database adapts to changes to the underlying container configurations? In this follow-up blog post, we’ll look into cluster management and orchestration of Galera cluster on Docker.
