Logging system-subsystem-application matrix

You can identify Relativity system components that log messages based on the system-subsystem-application designation. When troubleshooting, use the system-subsystem-application matrix to configure logging to target specific Relativity components.

Relativity systems

Systems are the top-level components of Relativity. They are typically IIS applications, Windows services, or executables.

Logging systems are as follows:

Agent Agent windows service running as kCura EDDS Agent Manager.
Invariant Relativity Invariant processing and conversion engine.
Relativity Relativity web site under IIS installed by default as /Relativity.
RelativityDistributed Relativity web site for downloads installed by default as /Relativity.Distributed.
RelativityRest Relativity RESTful web services installed by default as /Relativity.Rest.
RelativityServices Relativity web services installed by default as /Relativity.Services.
RelativityWebAPI Relativity web services installed by default as /RelativityWebAPI.
ServiceHost Windows service for running hosted services. Installed by default as kCura Service Host Manager.

Agent windows service running as kCura EDDS Web Processing Manager.

The following image presents the Relativity components hosted in IIS. They correspond to the logging systems listed in the table above.


Subsystems are Relativity components called from one or more systems. Generally, they are designated based on similar functionality.

Logging subsystems are as follows:

Container Web API for dynamic endpoints for RESTful services.
CustomAgent Background process of an agent that is part of an application or a resource file.
CustomPage Custom Pages are IIS applications deployed under /Relativity/CustomPage/<GUID>.
EventHandler Event handlers that run custom code build on the Relativity platform.
IdentityServer Authentication server that is used for managing tokens for user login.
Kepler Web API for dynamic endpoints for RESTful services.
RelativityAgent Background process of an agent that is part of the Relativity.
InvariantAPI Invariant API hosted in the Invariant Queue Manager service for processing and conversion requests.
InvariantAdminAPI Invariant Admin API hosted in the Invariant Queue Manager service for managing processing workers.

Relativity applications

Applications are unique identifiers of the context the code is running in. Applications are identified by GUID.

Logging applications are as follows:

Custom Relativity applications can also use logging and be identified by GUID.
