LibreNMS vs Riemann: What are the differences?

Introduction

When comparing LibreNMS and Riemann, there are several key differences that separate the two monitoring systems.

1. Data Storage: LibreNMS uses a MySQL database to store monitoring data, while Riemann utilizes an in-memory storage system which allows for real-time data processing and analysis without the need for persistent storage.

2. Alerting System: LibreNMS provides a robust alerting system that allows users to set up customizable alerts based on specific criteria, whereas Riemann focuses on event processing and does not offer the same level of alerting functionality out of the box.

3. Monitoring Scope: LibreNMS is primarily focused on network monitoring and management, providing comprehensive visibility into network infrastructure, while Riemann is designed for monitoring and analyzing distributed systems and applications.

4. Scalability: Riemann is known for its scalability and high performance in processing large amounts of data streams in real-time, making it suitable for monitoring complex and dynamic environments, whereas LibreNMS may face limitations with scalability in larger deployments.

5. Ease of Configuration: LibreNMS is known for its user-friendly interface and easy setup process, making it accessible for users with varying levels of technical expertise, while Riemann requires a deeper understanding of its configuration language and concepts to properly implement and customize monitoring tasks.

6. Community Support: LibreNMS has a large and active community of users and contributors, providing a wealth of resources and support for troubleshooting and expanding the platform, whereas Riemann has a smaller but dedicated community focused on its specific use cases and functionalities.

In Summary, LibreNMS and Riemann differ in terms of data storage, alerting system, monitoring scope, scalability, ease of configuration, and community support.
