Starting the Logging Service

The Doradus server enables the Logging service when it is started with the following option in the doradus.yaml file:

storage_services:

- com.dell.doradus.logservice.LoggingService

If the LoggingService is the first storage service listed, it becomes the default for new applications. Otherwise, new applications must use the StorageService option to select the LoggingService. For example (in JSON):

{"MyLogs": {

"options": {"StorageService": "LoggingService"},

...

}

Details of installing and configuring the Doradus server are covered in the Doradus Administration document, but here’s a review of the ways Doradus can be used:

•	Standalone: The Doradus server can be started as a standalone application using the provided Jetty web server to serve the REST API. When Doradus is built using Maven, an example command line from the directory {doradus_home}/doradus-jetty is:

java -cp ./target/classes:./target/dependency/* com.dell.doradus.core.DoradusServer

Command line arguments can be added to such as “-restport 5711” to change the REST API port to 5711.

•	Tomcat: Doradus can use Apache Tomcat to host its REST API. The doradus-tomcat folder provides a README file with instructions.

•	Windows service: Doradus can be started as a Windows service by using the procrun package from Apache Commons. See the Doradus Administration document for details.

•	Embedded app: Doradus can be embedded in another JVM process. This is especially useful for bulk load or other applications where performance is critical. As an embedded application, Doradus is started by calling the following method:

com.dell.doradus.core.DoradusServer.startEmbedded(String[] args, String[] services)

where:

•	args is the same arguments parameter passed to main() when started as a console application. For example {"-restport", "5711"} sets the REST port to 5711.

•

services is the list of Doradus services to initialize. Each string must be the full package name of a service. Required services are automatically included. An embedded application must include at least one storage service. Other services should be included when the corresponding functionality is needed. See the comments in doradus.yaml for a list of the current services.
