The Best Cassandra Monitoring Tools

A distributed NoSQL database management system called Cassandra is built to handle enormous amounts of organized and unstructured data across several commodity computers. For modern applications, it is an open-source database management system that offers high availability, fault tolerance, and scalability.

The peer-to-peer paradigm, which is the foundation of Cassandra’s architecture, distributes data among a cluster of computers. A piece of the data is stored and processed on each node in the cluster. As a result, Cassandra can offer linear scalability, high availability, and fault tolerance.

To maintain the system’s dependability and effectiveness, Cassandra’s performance and health must be closely monitored because it is built to handle large amounts of data. We’ll talk about the top Cassandra monitoring tools in this article so you can keep an eye on your cluster’s functionality and general health.

How does Apache Cassandra work?

Apache Cassandra is a NoSQL decentralized database system that is open-source, totally accessible, and capable of managing enormous amounts of data duplicated over numerous computer units while retaining excellent stability. Netflix and Spotify, for example, have adopted Apache Cassandra. The official Apache website offers a free download of Cassandra.

Although Cassandra has built-in fault tolerance and other characteristics, it still needs to be managed well. To provide the greatest performance and prevent security incidents, a network monitoring tool must be used to assess the functionality and health of databases.

Key Features of Apache Cassandra

  • Engineered to manage enormous volumes of data across several servers; Extremely scalable and distributed.
  • Peer-to-peer design for high availability and fault tolerance; optimized for workloads that include a lot of writing; strong assurances of consistency to assure accurate data;
  • Support for ACID transactions, a flexible data model for structured, semi-structured, and unstructured data.
  • Cross-datacenter replication for disaster recovery and data backup.
  • Built-in data compression for efficient data storage and support for unique indexing and query languages.
  • Interoperability with well-known programming frameworks and languages.
  • An open-source community that is active and regularly updates and improves.

Here is our list of the best tools to monitor Apache Casandra:

  1. SolarWinds Server & Application Monitor Excellent for keeping an eye on Linux or Unix, including node statistics, network health, and tracking.
  2. Datadog Apache Cassandra Monitor A database monitoring tool from a cloud platform, Datadog Apache Cassandra Monitor is a system infrastructure monitoring package that is tied into an application dependency map.

The Best Tools for Monitoring Apache Casandra

1. SolarWinds Server & Application Monitor

SolarWinds Server & Application Monitor

A clever and potent Cassandra performance monitoring tool to improve database performance is the SolarWinds Server & Application Monitor (SAM). To avoid performance issues like network congestion and service outages that could hurt end users, Cassandra’s monitoring requires an organized strategy.

Key Features:

  • Adds new widgets to the dashboard to alter its design
  • Often check the Cassandra database
  • Control several Cassandra monitoring dashboards from a single location
  • dependency maps for infrastructure
  • Build intelligent alerts for the Cassandra server-appropriate thresholds to be informed of urgent issues

Installing this monitoring tool is simple, and its first configuration may be carried out with the aid of its auto-discovery process with equal ease. It is intended to find and fix the root causes of Apache Cassandra’s performance issues. Users can also delve further into particular Cassandra clusters thanks to it. The user can also design personalized notifications using this tool.


  • May monitor infrastructure resource utilization as well as indicators related to Apache
  • Proactive warnings are sent out when performance deviates from the norm.
  • Supports Linux and Unix deployments fully.


  • Must set aside time to research all monitoring options

Moreover, SolarWinds Server & Application Monitor allows you to build up personalized notifications. Increased delay or continuing hint activity are some of the variables that are tracked. The All Active Alerts page, which provides a list of all currently active alerts and information on their origin and duration, allows users to view notifications.

2. Datadog Apache Cassandra Monitor

Datadog Apache Cassandra Monitor

Datadog is a complete monitoring tool for Apache Cassandra deployments that also features a wide range of functionality for connections, events, apps, and network architecture monitoring. There are numerous applications supported by this SaaS (Software-as-a-Service) infrastructure model, including Apache Cassandra, continuous profiling, distributed tracing, and many more.

Key Features: 

  • Real-time representation of adjustable parameters and actionable information
  • To quickly evaluate response streams, a simple log analysis framework and auto-pattern recognitions are used

  • It is simple to identify downward Cassandra queries and data restrictions thanks to thorough delay splitting and edge application monitoring
  • Make unique drag-and-drop data visualization charts in a flash

If the default screen looks overly crowded, you can design your own home page using the metrics that are most important to you. Widgets from different sites can even be combined to create a stack overview that displays database, server, and network performance overviews all in one location.

It is impossible to constantly monitor all of your database’s performance statuses. This is not a problem, though, because Datadog Infrastructure establishes performance thresholds for each statistic and notifies you when one is exceeded. Instead of spending all of your time monitoring your Apache Cassandra databases, this service allows you to go on to other duties.


  • Gives network administrators a comprehensive view of the performance and usability of the network by monitoring both internally and externally
  • Supports auto-discovery that dynamically creates network topology maps
  • The network reflects changes in almost real-time


  • Would like to see a longer trial period

Datadog is a subscription-based service that is broken up into different monitoring sections. The system’s constituent parts are charged separately, either regularly or as needed. When compared to yearly pricing, on-demand payment increases the cost of the goods by about 17 to 20%.
