Redis is an open-source in-memory data store that is commonly used as a database, cache, session manager, and message broker. It is is known for its low-latency storage, versatile data structure support, compatibility with various programming languages, and user-friendly interface.
Redis offers some advanced features like scalability, support for transactions, replication and pub/sub messaging. It is commonly used for caching, fraud detection, real-time analytics, messaging, session management, and much more. In this article, we will explore 10 of the best Redis monitoring tools.
Why is Redis monitoring necessary?
Redis, being a database management system heavily reliant on main memory for data storage, requires monitoring of critical memory metrics. These include used memory, memory fragmentation ratio, cache hit ratio, evicted key stats, and blocked clients. Redis monitoring tools provides detailed insights into these memory stats, ensuring comprehensive monitoring of both individual databases and overall system infrastructure health.
In addition to memory metrics, monitoring network traffic is also crucial to identify any unexplained changes in connections between applications and the Redis data source. Robust Redis monitoring solutions allow for continuous monitoring of network parameters such as the number of connected and blocked clients, rejected connections, and connection stats, including the count of concurrent connections. By tracking these network metrics, potential network-related issues can be proactively identified and addressed.
Another important benefit of monitoring Redis is that it helps with capacity planning. Tracking resource consumption metrics such as memory usage allows you to estimate future growth and plan for scalability. It also means that you can receive alerts when memory usage exceeds your expectations and act decisively to prevent resource exhaustion.
Here is our list of the top ten Redis monitoring tools out there:
