List of the Top 3 Time Series Databases for VictoriaMetrics in 2025

Elevate your monitoring and alerting strategies by utilizing a leading open-source tool known as Prometheus. This powerful platform organizes its data in the form of time series, which are essentially sequences of values linked to specific timestamps, metrics, and labeled dimensions. Beyond the stored time series, Prometheus can generate temporary derived time series based on the results of queries, enhancing versatility. Its querying capabilities are powered by PromQL (Prometheus Query Language), which enables users to real-time select and aggregate data from time series. The results from these queries can be visualized as graphs, presented in a table format via Prometheus's expression browser, or retrieved by external applications through its HTTP API. To configure Prometheus, users can employ both command-line flags and a configuration file, where flags define unchangeable system parameters such as storage locations and retention thresholds for disk and memory. This combination of configuration methods offers a customized monitoring experience that can accommodate a variety of user requirements. If you’re keen on delving deeper into this feature-rich tool, additional information is available at: https://sourceforge.net/projects/prometheus.mirror/. With Prometheus, you can achieve a level of monitoring sophistication that optimizes performance and responsiveness.

VictoriaMetrics Cloud enables users to deploy VictoriaMetrics Enterprise on AWS seamlessly, eliminating the need for traditional DevOps tasks such as configuration, monitoring, log collection, security management, software updates, protection, or backups. By utilizing AWS for our VictoriaMetrics Cloud, we offer user-friendly endpoints designed for efficient data ingestion, while VictoriaMetrics handles all aspects of software upkeep and ensures optimal settings are in place. Key features of VictoriaMetrics Cloud include its ability to seamlessly integrate with Prometheus; users can configure Prometheus, Vmagent, or VictoriaMetrics to send data to the Managed VictoriaMetrics, and then utilize the provided endpoint as a Prometheus source in Grafana. Each instance of VictoriaMetrics Cloud operates within its own isolated environment, preventing any potential interference between instances. Furthermore, scaling instances up or down can be accomplished in just a few clicks, providing users with flexibility based on their needs. Additionally, the service incorporates automated backups, offering peace of mind and data security.

OpenTSDB consists of a Time Series Daemon (TSD) and a collection of command line utilities. Users mainly interact with OpenTSDB by managing one or more standalone TSDs, which operate without a centralized master or shared state, thereby providing the flexibility to run numerous TSDs as required to handle different workloads. Each TSD relies on HBase, an open-source database, or the Google Bigtable service for the effective storage and retrieval of time-series data. The data schema is optimized for performance, allowing for quick aggregations of similar time series while also reducing storage needs. Users can access the TSD without requiring direct interaction with the backend storage system. Communication with the TSD is facilitated via a simple telnet-style protocol, an HTTP API, or an intuitive built-in graphical user interface. To start using OpenTSDB, users must first send time series data to the TSDs, and there are numerous tools designed to help import data from various sources into the system. Ultimately, OpenTSDB's architecture prioritizes both flexibility and efficiency in the management of time series data, making it a robust solution for diverse user needs.
