OpenC3 COSMOS 5.1.0 - Modern, Production Ready, Command and Control

Welcome to OpenC3 COSMOS 5.1.0!

The COSMOS name is back! We have completed an agreement to formally take over development of COSMOS and are now offering commercial licensing to customers who want the additional scaling and security functionality in our COSMOS Enterprise Edition, or for our COSMOS Base Edition if the AGPLv3 license doesn't work well for them.

5.1.0 is a major release with key new features and performance enhancements. It also marks the end of the developmental 5.0.x series, and indicates that OpenC3 COSMOS 5 is now fully production ready! Going forward all releases will follow a versioning convention where the second digit 5.X will change when breaking changes are introduced, and the third digit 5.X.Y will change for minor or non-breaking changes that should be backwards compatible.

This release is highlighted by the following major Improvements to logging, data reduction, and the streaming API:

  • 4x less disk utilization.
    • With up to 5x less disk space required to store decommutated data, and an almost 2x reduction in the storage of raw data.
  • Added a new Bucket class to allow direct bucket integrations with cloud providers without requiring Minio.
    • AWS will be supported in our Base Edition, and other clouds in our Enterprise Edition.
  • Data reduction updated to log samples for all non-numeric items
    • This allows quick queries of every telemetry item in the COSMOS database
  • Logging changed from "file per packet" to "file per target"
    • Greatly reduces the number of files generated and the number of files required to be accessed to playback all data
  • Log files are now written in a buffered fashion that stores packets in guaranteed time order
  • Log file format changes are not backwards compatible.
    • Older log files will need to be migrated to the new format to be accessed by the Streaming API. Please contact support@openc3.com if you would like help migrating existing log files

Other Highlighted Improvements In This Release

  • Telemetry value displays now turn purple to indicate stale values
  • Added pause button to log messages in CmdTlmServer
  • Removed the gems bucket in favor of the /gems shared folder
  • Added support for OpenTelemetry and Jaeger to help debug mission specific performance issues
  • Added the ability to create screens automatically for any packet with the New Screen button
  • The API methods connect_interface and connect_router now support reinitializing with new parameters. This can allow changing IP addresses at runtime.
  • Added the ability to open and close TlmViewer screens, from screens
  • Packet received counts now survive restarts and continue where they left off
  • User selectable colors for TlmGrapher items
  • Added a QUIET command to the demo INST targets to allow running the demo without constant limits violations
  • Numerous dependency updates

Key Bug Fixes

  • The Limits API is now fully functional. Previously enable/disable limits and set_limits were not taking effect.
  • Setting TlmViewer widget widths now work correctly
  • Removed an issue where ScriptRunner scripts could output too much to STDOUT causing crashes
  • Fixed XTCE converter
  • Removed partially implemented Admin plugin download button
  • Fixed issues editing TlmViewer screens
  • Fixed certain cases of decom of array items
  • Moved blocking in get_packets to client side code to prevent long API calls
