Agent Manager (REST)

The Agent Manager service exposes multiple endpoints that you can use to programmatically manage agents in your Relativity environment. It includes the following features:

  • Supports create, read, update, and delete operations on agents.
  • Provides helper endpoints used to retrieve agent types and agent servers. Use these endpoints to determine if a server supports the agent type that you want to add to it.
  • Validation endpoints used to check whether an operation results in the number of agents exceeding the maximum or falling below the minimum limits. These endpoints are available for create, update, and delete operations. For example, you can check if adding an agent exceeds the maximum number allowed on a server.

Sample use cases for the Agent Manager service include:

  • Adding new worker agents when multiple jobs are submitted to the OCR or Branding queues.
  • Deleting worker agents that are unresponsive.
  • Developing a custom monitoring tool for messages logged by agents.

You can also use the Agent Manager service through .NET. For more information, see Agent Manager (.NET).

Note: To implement your own custom agents, use the Agents API. For more information, see Agents.

Set the path parameters as follows:

Postman sample file

You can use the Postman sample file to become familiar with making calls to endpoints on the Agent Manager service. To download the sample file, click Agent Manager Postman file.

To get started with Postman, complete these steps:

  1. Obtain access to a Relativity environment. You need a username and password to make calls to your environment.
  2. Install Postman.
  3. Import the Postman sample file for the service. For more information, see Working with data files on the Postman web site.
  4. Select an endpoint. Update the URL with the domain for your Relativity environment and any other variables.
  5. In the Authorization tab, set the Type to Basic Auth, enter your Relativity credentials, and click Update Request.
  6. See the following sections on this page for more information on setting required fields for a request.
  7. Click Send to make a request.

Client code sample

To use the Agent Manager service, send requests by making calls with the required HTTP methods. See the following base URL for this service:

Copy 
<host>/Relativity.rest/api/relativity.agents/workspace/-1/agents

Note: For the workspace identifier in the URL, use -1 to indicate the admin-level context. This value is required for all URLs in the Agent Manager service. For additional guidelines, see Agent Manager (.NET).

You can use the following .NET code as a sample client for creating an agent. This code illustrates how to perform the following tasks:

  • Instantiate an HttpClient object for sending requests to the Agent Manager service.
  • Set the required headers for the request. For information on setting headers, see HTTP headers.
  • Initialize variables with the values for type of agent to create, and the server where it should be added.
  • Set the url variable to the URL for creating an agent. For more information, see Create an agent.
  • Set the JSON input required for the operation.
  • Use the PostAsync() method to send a post request.
  • Return the results of the request and deserialize it.
Copy 
public async Task<int?> RetrieveArtifactViewFieldIdExample()
{
    int? result = null;
    using (HttpClient client = new HttpClient())
    {
        client.DefaultRequestHeaders.Add("X-CSRF-Header", "-");
        client.DefaultRequestHeaders.Add("Authorization", "Basic " + Convert.ToBase64String(Encoding.GetEncoding("ISO-8859-1").GetBytes("test@test.com:SomePassword")));
        client.DefaultRequestHeaders.Add("X-Kepler-Version", "2.0");
        client.BaseAddress = new Uri("https://localhost/");

        var agentTypeId = 1015253;
        var agentServerId = 1016892;

        string inputJSON = $"{{\"AgentRequest\":{{ \"AgentType\": {{ \"Secured\": false, \"Value\": {{ \"ArtifactID\": \"{agentTypeId}\" }} }}, \"AgentServer\": {{ \"Secured\": false, \"Value\": {{ \"ArtifactID\": \"{agentServerId}\" }} }}, \"Enabled\": true, \"Interval\": 10, \"LoggingLevel\": 1, \"Keywords\": \"keywords\", \"Notes\": \"notes\" }} }}";
        var url = "/Relativity.REST/API/Relativity.Agents/workspace/-1/agents/";
        var response = await client.PostAsync(url, new StringContent(inputJSON, Encoding.UTF8, "application/json"));
        response.EnsureSuccessStatusCode();
        var content = await response.Content.ReadAsStringAsync();
        result = JsonConvert.DeserializeObject<int>(content);
    }

    return result;
}

When the agent is successfully updated, the response returns the status code of 200.

Delete an agent

You can programmatically remove an agent from Relativity after it has finished executing, or you can remove it immediately by forcefully deleting it. When you forcefully delete an agent, the system doesn't wait for it to finish executing. In general, use a force delete when an agent has become unresponsive.

Delete an agent

To remove an agent from Relativity after it has finished executing, send a DELETE request with a URL in the following general format:

Copy 
<host>/Relativity.rest/api/relativity.agents/workspace/-1/agents/{ToDelete}

Set {ToDelete} to the Artifact ID of the agent that you want to delete.

The body of the request is empty. When the agent is successfully deleted, the response returns the status code of 200.

Forcefully delete an agent

To remove an agent from Relativity immediately, send a DELETE request with a URL in the following general format:

Copy 
<host>/Relativity.rest/api/relativity.agents/workspace/-1/agents/{ToDelete}

Set {ToDelete} to the Artifact ID of the agent. In the body of the request, set the force field to true.

Copy 
{
    "force" : true
}

When the agent is successfully deleted, the response returns the status code of 200.

Validate a create, update, or delete operation

Before you attempt to add, update, or delete an agent, you can perform a check to verify the success of the operation. For detailed information, see Validation and compatibility checks.

Review the following information about agent validation:

  • In Relativity, each agent type has a maximum or minimum number of required agents for an instance, server, or resource pool. The Agent Manager service provides validation endpoints that help you answer questions about whether the operation that you want to perform may result in exceeding the required number of agents. For example, Relativity permits only a single Case Manager agent. If you try to create a second agent, the API returns an error indicating that you have exceeded the limit.
  • The validation methods on the Agent Manager service indicate whether the number of a specific agent type exceeds maximum limit or falls short of the minimum limit. It doesn't indicate the required limit for an agent type. To obtain this information, see Managing and setting Relativity agent quantity limitations on the Relativity Documentation site.
  • Use the Object Manager service if you want to know the number of agents of a specific type that exist in your Relativity instance. For more information, see Object Manager (REST).

Validate a create operation

To verify that you can add an agent to a Relativity environment or server, send a POST request to the following URL:

The body of the request is empty. If you can successfully delete the agent, the response returns the status code of 200. Also, see Failed validation responses.

Failed validation responses

When a validation check fails, the response varies depending on the reason for the failure. The AgentInstanceLimit enumeration contains constants that identify the reason for a failed validation check:

  • MinPerEnvironment - the environment has the recommended minimum number of agent instances.
  • MaxPerEnvironment - the environment has the maximum number of agent instances allowed.
  • MinPerResourcePool - the resource pool has the recommended minimum number of agent instances.
  • MinPerServer - the agent server has the recommended minimum number of agent instances.
  • MaxPerServer - the agent server has the maximum number of agent instances allowed.
  • LastPerEnvironment - the last instance of the agent type in the environment is being disabled or deleted.

The following examples illustrate possible JSON responses for validation checks:

  • You perform a validation check for creating agent in an environment. The following response indicates that the environment already has the maximum number of agent instances allowed.
    Copy
    {
       "Limit":"MaxPerEnvironment"
    }
  • You perform a validation check for deleting an agent from a server. The following response indicates that the agent server has the minimum number of agent instances. In addition, it includes the Artifact ID and name of the server.
    Copy
    {
       "Limit":"MinPerServer",
       "AgentServer":{
          "Secured":false,
          "Value":{
             "ArtifactID":"1016892",
             "Name":"Agent Server One"
          }
       }
    }
