RT Tracker

RT Tracker provides continuous visibility into web performance by running configurable checks from multiple regions against a target URL. It collects latency in milliseconds, availability, HTTP status, and error signals, producing per-check timelines and aggregated summaries. This enables performance engineers, site reliability engineers, and developers to quantify user-perceived latency, verify uptime commitments, and detect anomalies before users are affected.
The tool supports synthetic monitoring out of the box and can incorporate optional real-user monitoring data when available. It calculates distribution-based metrics (p50, p90, p95, p99) and SLA metrics, stores historical trends, and supports alerting rules when latency or availability breach thresholds. Users can define regions, protocols, and authentication methods to mirror production access patterns.
Key values include multi-region coverage, low overhead checks, and straightforward export options. Use cases include post deployment validation, SLA verification with vendors, capacity planning through trend analysis, and incident triage via precise response-time baselines. Outputs are machine friendly (JSON, CSV) and human friendly for stakeholders.
The architecture emphasizes modular checks, pluggable data sources, and simple integration hooks with incident management systems. Over time, teams gain actionable dashboards, faster MTTR, and more reliable uptime statistics, enabling data-driven prioritization of performance improvements.
