Online RRD Viewer

The Online RRD Viewer is a focused data visualization tool that reads Round Robin Database files and renders time-series charts for one or more data sources. It supports standard consolidation functions (AVERAGE, MAX, MIN) and variable time ranges, enabling quick trend analysis and capacity planning. The tool operates in a read-only mode, consuming RRD data and producing a scalable vector graphic that can be embedded in reports or dashboards. Conceptually, it samples data at a chosen resolution, aggregates values per time step, and maps the results to a chart with labeled axes and color-coded series. Users benefit from instant visual insight into seasonal patterns, counter resets, and anomalies across multiple DS, without needing to install heavy graphing stacks. Core value lies in rapid, shareable visuals that align with ops workflows and incident post-mortems. Use cases include monitoring server load, network throughput, or application metrics stored in RRDs, comparing multiple DS side-by-side, and exporting SVGs for documentation. The tool emphasizes reliability, supports remote or local RRD sources, and provides a consistent, standards-aligned rendering pipeline that respects DS-specific units and scales.
