Contrail® 8 is here! — OneRain Incorporated is pleased to announce a major new software release for its flagship platform.

In keeping pace with the ever-changing technologies, advances in security, and evolving requirements of their clients, OneRain announced the release of Contrail® 8—the next generation of their flagship software suite for real-time environmental monitoring.


Contrail is the leading enterprise-level software platform that collects, processes and delivers real-time environmental sensor data from local hydrometeorological networks and other external sources for Web-based dissemination, visualization, monitoring and automated alerting.

Included in this major update is the core Contrail software package, as well as Contrail Inventory plus, Contrail Camera, and Contrail TDMA Manager.

Much More…

New collector and services managers allow for more easily configuring, including easily switching data collection and services between instances of Contrail instances for faster disaster recovery. Users can add notes to any alarm rule to document with additional information. Updated search allows users to quickly get to the information more easily. Enhanced support tools allow for the Contrail team to more easily diagnose and troubleshoot any issues with the software. Additional software configuration options for base station owners.



Contrail 8 is considered a major operating system and application upgrade from Contrail 6, which will now be placed into Long-term Support (LTS). This software upgrade is available to all OneRain-hosted Contrail Web and Contrail Server users as well as licensed on-premise Contrail Base Station users current with standard maintenance.

This upgrade is automatic for Contrail Shared Web and Contrail Cloud Server instances—there’s no need for these customers to take action to receive the update.

For agencies that are running licensed on-premise Contrail Base Station, OneRain’s Contrail Support team will work directly with the agency’s IT department to provision a new server to facilitate the upgrade and migration from existing servers, and enable the running of systems in parallel for a period during the transition.
