Free Storage, SAN and LAN Performance and Capacity Monitoring
The tool offers you end-to-end views of your storage environment including LAN and SAN. It can save you significant money in operation monitoring and by predicting utilization bottlenecks in your virtualized environment.
You can also generate policy-based alerts, view overall health status of your systems, provide capacity reports and forecasting data.
  • Real-time storage, SAN and LAN performance visibility in multi-vendor environment
  • Historical reporting (graph, CSV, PDF, XLS)
  • Alerting based on performance tresholds
  • Event monitoring

Product roadmap

Why use STOR2RRD?

  • It comes with the same philosophy as its sister product LPAR2RRD.
    Get information you are looking for in 2 - 3 clicks!
  • You can find utilization of any attached storage in a simple graphical form comprehensible to anyone from technician to management level
  • It is free for use, you do not need to invest in expensive commercial solutions
  • It does not require ANY administration past initial setup
    in comparison to other commercial tools that require dedicated and trained staff

Our mission

Bring easy solution to market for performance monitoring and capacity planning of your highly virtualized environment with a simple and easily comprehensible UI.
Our tools should act as the front-end tools which easy identify load abnormality and locate problems on the infrastructure level.
