What's new in Edge Flow Manager

Edge Flow Manager allows you to manage, control, and monitor agents that are deployed on edge devices in IoT implementations. You can use these agents to collect real-time data from the devices to create and push actionable intelligence and insights directly to the data's origin.

Edge Flow Manager 2.4.0 introduces the following new features and improvements:

Flow lifecycle control

You can now start and stop flows in Cloudera Edge Management providing greater operational flexibility and safer deployment management.

Flows are started automatically after deployment, and you can:
  • Start and stop flow execution at both the agent class and individual agent levels
  • Start and stop flows using the Edge Flow Manager UI or API
  • Pause flows for maintenance
Upgrade impact:

After upgrading, existing flows remain stopped until you start them manually.

Supported agent versions
This feature is version-dependent and supported by both C++ and Java agents.
  • Cloudera Edge Management MiNiFi C++ Agent 1.26.02 is the first C++ agent version that supports flow lifecycle control.
  • Support for flow lifecycle control is not yet available for the Cloudera Edge Management MiNiFi Java Agent.
Agent binaries management
Edge Flow Manager now includes a centralized repository for managing agent binaries. You can:
  • Download agent binaries directly from the Cloudera archive
  • Upload custom agent binaries for use in deployments
  • Automatically distribute binaries across Edge Flow Manager nodes
  • View and manage binaries in the new Agent Binaries Repository page
  • Remove obsolete or unused binaries using the UI
Enhanced processor configuration

Extra configuration tabs are now available for the JoltTransformJSON and UpdateAttribute processors, providing a more tailored editing experience in the Flow Designer.

Configuration inconsistency alerts

Edge Flow Manager now detects and alerts you about configuration inconsistencies within an agent class, including:

  • Property synchronization in progress
  • Resource synchronization in progress
  • Manifest out-of-sync conditions

These alerts help users identify and resolve configuration issues. Out-of-sync manifest alerts link directly to the Agent Manager, enabling faster issue resolution.

Agent manifest viewer

A new Agent Manifest tab has been added to the Agent Manager interface.

You can:
  • View the agent manifest as JSON directly within the Agent Manager UI
  • Copy a direct link to the agent manifest for easy sharing or troubleshooting

This improves transparency and simplifies inspection of agent configurations.

Referencing assets from parameters

You can now reference assets, such as flow definitions and templates, from different contexts within Edge Flow Manager. This improves the reusability of assets and the collaboration across projects and teams.

Windows agent deployment behavior change

When deploying MiNiFi C++ Agent 1.26.02 on Windows using the agent deployer, the agent is installed to the standard installation directory, consistent with the Windows installer behavior. Previously, the deployer installed the agent into the current working directory.
