Connect Agent was designed with a few key points in mind to give you a simple and secure experience:
Lightweight - Consumes about 4 MB of disk space and about 11 MB of RAM.
Always on - The Connect Agent service is always running in the background. Even when there is no Internet connection, the agent will always keep the device accessible remotely when the connection returns.
Zero dependencies - Designed to run like an add-on, i.e., no additional installations are required to make it work.
Smart network behavior - Only communicates as a client, using port 443 with the Connect Server. No open network ports or listening servers are required on the edge and IoT devices.
Connect Agent sends regular heartbeat messages to the Server. The messages include updates on your edge device’s up/down status, CPU, RAM, and disk usage. The heartbeat messages also provide updates on any of the processes and custom data being monitored.
In addition, the Connect Agent:
Facilitates the software updates to the edge device according to the blocks defined in the Update Flows
Enables remote access and control commands to the device
Enables creation and configuration of firewall rules on the devices
Retrieves logs and any kind of data file stored on the device according to your request
The Connect Agent is project linked. This allows agents in different projects to have different configuration settings such as communication cycle and user access parameters. If you have multiple projects configured and you register a new agent, you will need to ensure that you associate the new agent with the intended project.
An agent acts as standalone software with regard to installation. If you re-install the same version of an agent on the same device, the new agent will have a different token and will be counted as a new device. In addition, the old device is not removed from the database in the Connect Server and appears in offline state in the web UI until you delete it.
Connect Agent is designed for easy installation and compatibility on any Linux-based operating system and is suitable for use on a variety of hardware architectures including SOC, SOM, and SBC, as long as the OS is Linux-based.
The Connect Agent is compatible with popular hardware platforms such as NVIDIA Jetson, BeagleBone, and Raspberry Pi, and will work with any hardware platform meeting the following specifications:
Minimum total device resources:
30MB RAM
30MB Disk space
Core Architecture:
ARM:
ARMv5, ARMv6, ARMv7, ARMv8 - 32 and 64 bit
Cortex-A required for all ARM processors
Intel: x86 and x86_64
You can use a wide range of operating systems, including Windows and the following Unix-based OSs:
Yocto-based build
Ubuntu
Debian
Centos
Raspberry Pi OS
Arch
Custom Debian build
Systemd/SysV (init.d) service manager must be installed on the client device.
If the ssh-client is not already on the device, the client will be installed by default when you download Connect Agent to the device.
The device must be configured to allow Write permission to the Connect Agent.
From time to time a new version of the Connect Agent will become available. The Connect Agent updates ensure that IoT devices are running the latest software and are able to communicate with the JFrog platform effectively.
The new agent version is not deployed automatically. When a new version is available, you can initiate an OTA update process at your convenience to update the agents on your connected devices. The update process takes place in the following stages:
Agent Version Management: Connect keeps track of the versions of the agents running on each device and compares them to the latest version available.
Notification: When a new version of the agent is available, a notification appears in the web UI and a release note will be available.
Initiation: In the Connect Agent Update page, you initiate the OTA update process.
Update Verification: Connect verifies that the update has been applied successfully to each device. If a device fails to update, Connect can retry the update or alert the appropriate personnel.
Post-update Verification: After the update process completes, Connect can verify that the new version of the agent is running (online/offline) on each device.
JFrog Connect Agent versions 7.0 and higher employ a trust mechanism that uses JSON Web Tokens (JWT) for secure interactions between the agent and a Connect project.
