Status Information

Diagnostic:

We provide a health check script that can show the state of our application.
The script is located at  /data/scripts/docker_health.sh. 
The script is taken from our repository in LF on VM spin.
The script calls a REST API in the FE and BE server.

BE health Check URL:

http://<BE server IP>:<BE server port>/sdc2/rest/healthCheck

The Back end health check provides the following INFO, in case one of the components is down the server will fail requests:

The Front end server health check places a REST call to the Back end server to check the connectivity status of the servers.

the status received from the Backend server is aggregated in the Frontend health Check response.

in addition to the info retrieved from the BE the info of the Frontend server is added for the Catalog and Onboarding

FE health Check URL:

 The logs are mapped from the docker to an outside path so that on docker failure the logs will still be available.


to change the log level in sdc:

  1. access the docker for FE or BE example docker exec -it <docker id > bash
  2. go to config/catalog-fe/logback.xml
  3. open the file for editing.
  4. in the file you can change the log level:

    <root level="INFO">
            <appender-ref ref="ASYNC_ERROR" />
            <appender-ref ref="ASYNC_DEBUG" />
            <appender-ref ref="AUDIT_ROLLING" />
            <appender-ref ref="ASYNC_TRANSACTION" />
            <if condition='property("enable-all-log").equalsIgnoreCase("true")'>
                    <then>
                            <appender-ref ref="ALL_ROLLING" />
                    </then>
            </if>
    </root>
    
    <logger name="org.openecomp.sdc" level="INFO" />
  5. change the root level to DEBUG to open all logs in SDC including the dependencies. (Note a lot of log output is created and it is hard to follow).
  6. open the logger by a package to enable only sdc spcific logs.
  7. it is important to note the opening the logs impacts the application performance so do not leave the system in debug level.
  8. the log configuration is runtime editable so no restart is required for the docker, just save the file and that is enough.

  1. What is the recommended restart procedure. It seems when we have a problem with SDC our only repair is to do a helm delete /helm deploy for all of SDC. Is there a script or set sequence to recover a failed pod like sdc-be.
