Contrail® Server

Contrail Server—cloud-hosted software for real-time data collection, hydrological data management, and monitoring of rainfall and weather-related information used in flood early warning, dam safety monitoring, road weather information, and more.

Contrail Server is a OneRain-hosted and managed virtual server resource running the full version of Contrail Base Station software in our secure industrial data centers. With Contrail Server, you’ll experience the same full features, access, and functionality as our on-premise Contrail Base Station solution (includes Contrail Analytics, Contrail Inventory Plus and Contrail ALERT2 TDMA Manager). Fixed subscription cost allows you to extend and load it with as many data sources, web views, custom reports, etc., as you require.

Flexible Deployment Options
More and more organizations are realizing the benefits of combining on-site and hosted Contrail software deployment options. With Contrail, you have three flexible options. Whether to host your own solution on-site, we host it for you (or combination of both), or choosing our software-as-a-service option, OneRain’s team of experts will help you assess which deployment solution achieves the highest availability and resiliency for your mission-critical operations.

Easily Configurable for Diverse Users
Your data may have to meet and serve the needs of many and different users, whether flood early warning, dam safety operations, emergency management, water quality, stormwater/wastewater management, or for public information. You can control access to the data set that each user or group of users can see. You can expose different data sets to different sets of users.

It’s easy to organize alarm delivery notifications whether individuals or groups or based on their roles, departments or teams. Automated delivery notifications to appropriate personnel to warn of possible problems or potential flood conditions ensures time for actions that reduce risk, minimize losses and enhances public safety.

Understand what’s going on end-to-end with your system
Any end-to-end warning system comprises a complete set of components. Contrail provides a powerful toolset that monitors your entire system performance, and enables you to perform rainfall intensity duration analysis, mass balance rainfall analysis, time series data export and bulk exporting of event data. Statistical analysis is performed on your datasets and is presented in easy-to-interpret sparkline graphs, tables and charts that let you see at a glance what’s going on.
