Logging Configuration Manager services

The REST API includes services that you can use to interact programmatically with the Relativity logging frameworkRelativity logging framework. The following services provide endpoints to support this functionality:

Logging Configuration Manager service - includes endpoints for creating, updating, and deleting configurations. This service also includes an endpoint for retrieving all existing configurations. For more information, see Configure logging .
Logging Rule Manager service - includes endpoints for creating, updating, and deleting rules. This service also includes an endpoint for retrieving all existing rules. For more information, see Rules.
Logging Sink Manager service - includes endpoints for creating sinks that write messages to files, Data Grid, SQL databases, or the Logentries website. This service also includes an endpoint for retrieving all existing sinks. For more information, see Sinks.

For example, you may want to use these services when implementing a custom page or application that provides a UI for configuring logging. Your custom UI may provide users with options for adding configurations, rules, and sinks.

The Relativity Services API also provides the same functionality for interacting programmatically with the Relativity logging framework. For more information, see Logging Configuration APIs.

Client code sample

To interact with an endpoint on one of the logging configuration services, send an HTTP request that makes a POST method call. See the following base URLs for each of the services:

Logging Configuration Manager service

Copy

<host>/Relativity.REST/api/Relativity.Services.LoggingConfig.ILoggingConfigModule/Logging%20Configuration%20Manager/

Logging Rule Manager service

Copy

<host>/Relativity.REST/api/Relativity.Services.LoggingConfig.ILoggingConfigModule/Logging%20Rule%20Manager/

Logging Sink Manager service

Copy

1
<host>/Relativity.REST/api/Relativity.Services.LoggingConfig.ILoggingConfigModule/Logging%20Sink%20Manager/

You can use the following .NET code as the REST client for interacting with the logging configuration services. The following sample code illustrates how to perform these tasks:

Instantiate an HttpClient object for sending requests and responses using the URL for an endpoint on one of the logging configuration services. This example uses the Logging Configuration Manager service to retrieve a collection of configurations.
Set the required headers for the request.
Set the variable call url to the URL for the retrieval operation.
Use the PostAsJsonAsync() method to send a post request.
Return the results of the request.

        //Set the required headers.
        httpClient.DefaultRequestHeaders.Add("X-CSRF-Header", "-");

        string url = " Logging Rule Manager/GetAllAsync ";
        rules = await httpClient.PostAsJsonAsync(url, null);
    }
    return rules;
}

Logging Configuration Manager

The Logging Configuration Manager service supports creating and deleting logging configurations. It also supports retrieving a list of all configurations currently stored in the EDDSLogging database. For more information, see Configurations.

Retrieve configurations

To retrieve a list of all configurations, send a request with this URL on the Logging Configuration Manager service:

Copy

1
<host>/Relativity.REST/api/Relativity.Services.LoggingConfig.ILoggingConfigModule/Logging%20Configuration%20Manager/GetAllAsync

This request doesn't require any input parameters.

The response returns the following fields:

Id - the Id for the configuration stored on the EDDSLogging database. For more information, see Configure logging .
Order - indicates the sequence in which this configuration is applied.
MachineName - the optional name of the machine that you want to collect logging information about.
System - the optional name of the system that you want to collect logging information about.
SubSystem - the optional name of the subsystem that you want to collect logging information about.
Application - the optional GUID for an application that you want to collect logging information about.
LoggingEnabled - a Boolean flag that indicates whether logging is enabled for this configuration.

      "SubSystem":"",
      "Application":"",
      "LoggingEnabled":true
   }

Create or update a configuration

To create or update a new configuration, use the following URL on the Logging Configuration Manager service:

Copy

1
<host>/Relativity.REST/api/Relativity.Services.LoggingConfig.ILoggingConfigModule/Logging%20Configuration%20Manager/CreateAsync

To create a new configuration, the request must include the Order field. The request can optionally include other fields, such as MachineName, System, and others. However, the only required field is the Order field.

To update a configuration, you must provide the Id field. This value is available on the record for the configuration in the EDDSLogging database, or by calling the GetAllAsync() method.

Note: If you don't supply an Id field for an update operation, then the service checks for a matching machine, system, subsystem, and application combination in order to make the update. If the service doesn't find a matching combination, then it creates a new configuration.

The following JSON illustrates how to update an existing configuration. It includes the required Id field, and optional fields for the configuration. For descriptions of these fields, see Retrieve configurations.

      "Application":"3E86B18F-8B55-45C4-9A57-9E0CBD7BAF46",
      "LoggingEnabled":"TRUE"
   }
}

The response returns a status code of 200 when the service successfully updates or creates a configuration.

Delete a configuration

To delete a configuration, use the the following URL on the Logging Configuration Manager service:

Copy

1
<host>/Relativity.REST/api/Relativity.Services.LoggingConfig.ILoggingConfigModule/Logging Configuration Manager/DeleteAsync

The request must include Id field for the configuration that you want to delete. This value is available on the record for the configuration in the EDDSLogging database, or by calling the GetAllAsync() method. The request can optionally include other fields, such as Order, MachineName, and others. However, the only required field is the Id. For descriptions of these fields, see Retrieve configurations.
