Custom Graphs to Monitor your MySQL, MariaDB, MongoDB and PostgreSQL Systems - ClusterControl Tips & Tricks

This blog post will show you how to add custom graphs to ClusterControl to monitor specific MySQL, MariaDB, MongoDB or PostgreSQL metrics.

Become a ClusterControl DBA: Performance and Health Monitoring

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.

How to Deploy PostgreSQL for High Availability

In this blog, we will review some important concepts of High Availability, possible database HA architectures and useful components when implementing PostgreSQL HA. Then we will see how to use ClusterControl to deploy an entire high availability stack for PostgreSQL.

How to Deploy MongoDB for High Availability

MongoDB provides ReplicaSets to help you address high availability database requirements. Although support for replication and failover is built-in, it is not enough for the database to be considered production-ready. That requires a set of policies and procedures, like getting alerted in case of performance slowdowns, anomalies or failures in a live environment. Backups are essential. Being able to automatically recover from different types of failures can drastically reduce downtime.

How to Deploy a Production-Ready MySQL or MariaDB Galera Cluster using ClusterControl

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.

Overview of the MongoDB Database Profiler

The MongoDB database profiler is a useful tool that can help gain insight into the performance characteristics of operations running inside your MongoDB instances. In this blog, we’ll learn how to use it.

How to Automate Database Workload Analysis with ClusterControl Performance Advisors

ClusterControl provides you with a set of monitoring and performance advisors to add stability to your database infrastructures. It enables you to detect and solve unique problems in your environments.

An Overview of Volume Level Replication for PostgreSQL Using DRBD

Volume level replication is a generic approach that not only applies to PostgreSQL, but also all relational databases. In this blog, we’ll show you how to use DRBD,  a distributed replicated storage system for Linux, to replicate your database for high availability.

A Developer’s Guide to MongoDB Replica Sets

This blog provides a high-level, developers view of achieving high availability with MongoDB using replica sets. It includes how-to instructions and tips and tricks for getting it right.

How ClusterControl Monitors your Database Servers and Clusters Agentlessly

Agentless monitoring is the collection of performance metrics from databases without installing any agent software on the servers being monitored. This approach is easy to manage and gets you up and running within minutes.

This blog post describes how ClusterControl uses the agentless approach to monitor databases.
