+## Portal Logging Configuration
+=================================================================================================
+Portal has two docker containers- portal and mariadb.
+The canonical logging implementation is only done for the container, portal.
+Portal has two sub-modules portal-be and portal-db each one has its own separate logback.xml file.
+Canonical logs will be generated at /var/log/onap/portal/
+=================================================================================================
+## Instructions for deployment
+=================================================================================================
+### Portal logging deployment for sub-module portal-be
+-------------------------------------------------------------------------------------------------
+  1. Log provider file is available at the path, /opt/apache-tomcat-8.0.37/webapps/ECOMPPORTAL/WEB-INF/classes, in the container.
+  2. Copy the canonical logback.xml from 'portal-be' directory (of gerrit) into the path mentioned in step 1.
+  3. Create the canonical path for logs, /var/log/onap/portal/portal-be on the host VM.
+  4. Provide write permissions for "others" users for directory created in step 3.
+  5. Volume-Mount: The portal container requires one host path mapped as volume in the container
+        
+      5.1. Log file path:
+        Host path -      /var/log/onap/portal/portal-be/ mapped to 
+        Container path - /var/log/onap/portal/portal-be/      
+      5.2. Log provider file path:              
+        Note: Log provider path cannot be configured externally as it is bundled inside a WAR.

+        Host path -      /var/log/onap/portal/portal-db/ mapped to 
+        Container path - /var/log/onap/portal/portal-db/
+        This is done so that the log files are also visible in the VM and then to the filebeat.
+      5.2. Log provider file path:              
+        Note: Log provider path cannot be configured externally as it is bundled inside a WAR.
