The Best Cassandra Monitoring Tools

Cassandra_Monitoring_Tool_10

Diego Asturias UPDATED: October 27, 2023

Cassandra is an open-source distributed NoSQL database management system widely known for its exceptional scalability, fault tolerance, high availability, and high performance. As with any database, monitoring is essential for ensuring its smooth operation. Fortunately, there are many tools for monitoring Cassandra, available for free and paid, that will provide you with valuable insights into the performance and health of the database.

Without a proper guide, it can be a daunting task to find the right one for your needs. So, we have compiled a list of the ten best Cassandra monitoring tools to help you select the right tool for your specific monitoring needs. 

Here is our list of the top Cassandra Monitoring tools:

How to Monitor Cassandra?

Monitoring the performance of Apache Cassandra is essential to identify any issues that could slow down or limit its resources. Fortunately, Cassandra provides different metrics on performance and resource utilization that can be helpful for monitoring. Cassandra exposes these metrics through JMX (Java Management Extensions) — a Java technology that monitors and manages Java applications.

When monitoring Cassandra, it is vital to keep track of the following metrics:

  • Throughput: A metric that refers to the number of reads and writes requests processed by Apache Cassandra over some time.
  • Latency: This metric refers to the time it takes for Cassandra to respond to a request, usually measured in milliseconds.
  • Disk usage: A metric that refers to the amount of disk space Cassandra uses on each node.
  • Garbage collection: A metric that refers to the process of reclaiming memory that Cassandra is no longer using.
  • Errors and overruns: The number of errors or failed requests encountered by Cassandra.

There are mainly three tools to view and monitor these Cassandra metrics. However, it is essential to note that such tools provide different monitoring levels, simple-to-advance analysis, and different visualizations of these Cassandra metrics.

  • The first option is Nodetool, the command-line interface that comes with Cassandra.
  • A second option is the most popular: JConsole — a graphical user interface that comes with the Java Development Kit (JDK); and integrations with external graphing and monitoring tools that support JMX/Metrics protocols.
  • The Metrics library: This is a popular open-source library for measuring and reporting performance metrics in Java applications.

So, you can get good Cassandra monitoring capabilities by using the above-mentioned tools. But to get the most out of these Cassandra metrics, including advanced collection, aggregation, intelligence, visualization, and alerting, you’ll need an advanced and robust Cassandra monitoring tool.

Advanced Cassandra Monitoring Tools

As mentioned in the previous section, one of Cassandra's most popular monitoring tools is Apache Cassandra's own monitoring tool, which provides metrics such as CPU usage, memory usage, and read and write latency. But in addition to Apache Cassandra's tool, many other monitoring tools are available, both free and paid. These tools provide a range of features, such as tracking the usage of critical resources, monitoring the health of the cluster and individual nodes, and providing detailed statistics on application performance.

For those using cloud-based services like AWS or Microsoft Azure, there are also Cassandra monitoring tools available specifically designed for these platforms. These tools provide insights into the performance of the database within the cloud environment and can help identify any issues that may arise.

The Best Cassandra Monitoring Tools

What factors to consider when choosing a Cassandra Monitoring tool?

When selecting a monitoring tool, it is essential to consider factors such as pricing, features, ease of use, and support services. Many tools offer free trials, which can be an excellent way to get a feel for the tool before committing to it.

Ultimately, the proper monitoring tool for your Cassandra database will depend on your specific needs and requirements. Whether you require a simple tool that provides an overview of the system, or a more complex tool that includes features such as tracing and cache management, there is a tool out there that meets your needs.
