MiNiFi Java agent updates

MiNiFi Java agents has periodic software updates made available independent of the EFM releases.

This section lists major features and updates for the independent CEM MiNiFi Java agent release.

March 30, 2023

CEM MiNiFi Java Agent - 1.23.02.1000 service pack includes the same features as the 1.23.02 release and a fix for the Too many open files error introduced in 1.23.02, which is caused by non-closed files in the heartbeat request.

February 15, 2023

CEM MiNiFi Java Agent - 1.23.02 release includes:
  • Property update command with the C2 protocol

    Implemented the UPDATE/PROPERTIES command. This command allows agents to update bootstrap properties using the C2 protocol. For more information, see Agent details in CEM.

  • Pushing assets to agents with the C2 protocol

    Implemented the UPDATE/ASSET command. This command allows agents to download artifacts into the specified assets directory as per instructed by the C2 server. For more information, see Using Asset Push command.

  • Using change ingestors for configuration updates is no longer necessary.
  • The following issues are fixed:
    • Hanging bootstrap commands when executing large flows.
    • Debug command fails on windows due to malformed input.
    • Many additional small improvements and stability fixes.

October 12, 2022

CEM MiNiFi Java Agent - 1.22.10 release includes:
  • Lightweight heartbeat support

    This reduces the payload size of the heartbeat and the agent sends the full agent manifest only if a change is detected. The functionality can be enabled with the c2.full.heartbeat=false property in the bootstrap.conf file.

  • Debug support through C2 protocol

    Debug bundles can be requested from EFM Agent Manager for the given agent. For more details, see Debug agent in CEM.

  • GZip C2 requests

    Using GZipped requests can be beneficial to prevent network saturation. To enable it, set the c2.request.compression=gzip property in the bootstrap.conf file.

  • Docker images released for multiple platforms (x86, ARM)
  • The following issues are fixed:
    • Missing required controller services for several processors
    • Fixed agent information values when running agent on Windows

July 28, 2022

CEM MiNiFi Java Agent - 1.22.07 release includes:
  • Initial release of the new MiNiFi Java agent based on the latest version of NiFi (1.16.3).
  • Includes heartbeat and update/configuration support over the C2 protocol.
