The 8 Best Tools for Monitoring Apache Cassandra

by John Doe

What is Apache Cassandra? Apache Cassandra is an open-source database management system. Apache Cassandra has been used by companies such as Apple, Spotify, Netflix, and Uber. The system is widely used because it is a fault-tolerant, scalable and decentralized database solution. Cassandra can be downloaded for free from the Apache website here.Even though Cassandra comes with features like fault tolerance built-in, it still needs to be managed effectively. Using a network monitoring tool to measure the performance and health of databases is necessary to deliver the best performance and avoid security events.There is lots of detail on the tools below, but for a quick summary, here is our list of the 8 best tools to monitor Apache Casandra:SolarWinds Server & Application Monitor (FREE TRIAL) Our top choice for Apache Cassandra monitoring. Great for monitoring Linux or Unix including nodes stats, tracking, and network health.Datadog Apache Cassandra Monitor (FREE TRIAL) An application performance monitor that covers database services and has great performance data visualizations.ManageEngine Applications Manager (FREE TRIAL) Also compatible with MongoDB, has a great dashboard that can monitor clusters and more.Dynatrace Automatically detects Apache Cassandra databases, can get into depth on the data it gathers.AppDynamics Also auto-detects Apache Cassandra databases and offers good monitoring and tracking options.SignalFx Similar to above options but is cloud-based. Good for setting alerts.Instaclustr Network monitor with a custom Cassandra monitoring API. Provides 20-second updates and a good cluster summary view.Instana This monitor is good at providing metrics right down to the node level.The best tools for monitoring Apache Casandra1.
