ROBIN Agent

ROBIN Agent is the module responsible for sending messages and commands between ROBIN Studio, ROBIN Orchestrator and ROBIN Robot:

when a robot is launched from any component of the platform, the launch is controlled via the ROBIN Agent;
real-time transfer of robot execution logs to ROBIN Orchestrator 2.0;
transmission of information about the status of the machine and its current workload to ROBIN Orchestrator.

Delivery option	Functioning Option	Path to the installed application
For me only	Application	C:/Users/<userName>/AppData/Local/Programs/Robin Platform/2.0.0/Agent
For all users	Operating system service	C:/Program Files/Robin Platform/2.0.0/Agent

Robot Player "Agent" settings tab

In the "Agent" section, it is possible to customize the logging of the ROBIN Agent.

For Standalone delivery

Characteristics of the settings of the "Agent" tab are presented in the table.

For Standalone delivery

No.	Setting	Characteristic
1	Log of frequent operations	If "true" is specified, the agent's frequently executed operations will be recorded in its log
2	Save all messages	If "true" is specified, the "messages.data" file will contain all messages exchanged between the agent and other components of the Robin platform.

Click on the "Save" button and restart the ROBIN Agent to save the changes.

For Enterprise and Cloud delivery

No.	Settings	Characteristics
	Checkbox Log of frequent operations	If this parameter is enabled, the agent's frequently performed operations will be recorded in its log. For example, ping commands. After updating the parameter, you need to restart ROBIN Agent
	Checkbox Cache robot dependencies	If caching is disabled, the dependencies will be removed from the machine after the robot is finished. Therefore, each time the robot is restarted, the action packages will be restored
	Checkbox Cache robots	If caching is disabled, then after the robot completes its work, its file will be deleted from the machine. Therefore, each time the robot is restarted, it will be downloaded to the machine again
	Checkbox Reconnection interval	The interval for reconnecting the agent to the server when the connection is broken. The value is specified in seconds. The minimum value is "5
	Checkbox Save all messages	Saving all incoming and outgoing messages. After updating the parameter, you need to restart ROBIN Agent
	Checkbox Interval for sending machine data	The interval for sending data about the resources of the machine. The value is specified in seconds. The minimum value is "5". After updating the parameter, you need to restart ROBIN Agent
	Checkbox Log .NET dependencies restore	If this parameter is enabled, information about the download .NET dependencies will be recorded in the agent log
	Checkbox Log Python dependencies restore	If this parameter is enabled, information about the download Python dependencies will be recorded in the agent log
	Checkbox Log Java dependencies restore	If this parameter is enabled, information about the download Java dependencies will be recorded in the agent log

Special conditions

When running robots in Robin Studio Enterprise, when restoring files with long names to a folder that itself has a long name, you may encounter limitations related to the MAX_PATH path length, which is defined by the Windows API as 260 characters.

If caching of robot dependencies is disabled, when restoring files in Robin Studio Enterprise there is not enough path length to download one of the engine's dependencies, moreover, after the robot is finished, the dependencies will be deleted from the machine. Therefore, each time the robot is restarted, the action packages will be restored.

To do this, you need to check the ROBIN Agent settings:

If "Do NOT cache robot dependencies" is selected in the ROBIN Agent settings,

then when running the robot on a .NET action (such as Show message), the robot terminates with an error that is related to the length of the MAX_PATH path.

Result

Package recovery error

Starting with Windows 10 version 1607, MAX_PATH with dependency caching disabled restrictions have been removed for many common Win32 file and directory functions. However, the application in use must agree to the new behavior.

To enable the new long path behavior for each application when robot dependency caching is disabled, some conditions must be met.

You can see more details here: https://learn.microsoft.com/en-us/windows/win32/fileio/maximum-file-path-limitation?tabs=registry#enable-long-paths-in-windows-10-version-1607-and-later

This problem can be solved by setting the registry manually. To do this, set the HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\FileSystemLongPathsEnabled registry to 1.

2. In versions higher than 2.24.0 the list of Robot Player "Agent" settings has been improved and in order for packages to be restored correctly and the robot to start and run without errors, it is sufficient to enable dependency caching in the ROBIN Agent settings.

Then, when running the same "Show message" action, the long path packets are fully restored and the robot works without error.

Displaying the status of the ROBIN Agent

Agent status is displayed by the connection status indicator in the workspace in the form of a circle with the letter "A".

Relevant for versions: Standalone, Enterprise, Cloud.

ROBIN Player:

If there are problems with the connection to the ROBIN Agent, there may be problems starting the robot. To diagNo.se possible problems, an Agent connection status indicator is placed on the application interfaces.

There are the following options for displaying the user information about the status of the Agent:

Standalone delivery option:

Green - ROBIN Player is connected to the Agent
Gray - ROBIN Player is No.t connected to the Agent

Enterprise\Cloud delivery option:

Green - ROBIN Player is connected to an Agent, Agent is connected to Orchestrator
Gray - ROBIN Player is No.t connected to the Agent
Red - ROBIN Player is connected to the Agent, the Agent is No.t connected to the Orchestrator
Yellow - ROBIN Player is connected to the Agent, reconnection to the Orchestrator is in progress
