 Troubleshooting
 ===============
 
+**NOTE**
+
+According to **ONAP** logging policy, **HV-VES** logs contain all required markers as well as service and client specific Mapped Diagnostic Context (later referred as MDC)
+
+Default console log pattern:
+
+::
+
+        | %date{&quot;yyyy-MM-dd'T'HH:mm:ss.SSSXXX&quot;, UTC}\t| %thread\t| %highlight(%-5level)\t| %msg\t| %marker\t| %rootException\t| %mdc\t| %thread
+
+A sample, fully qualified message implementing this pattern:
+
+::

+
+
+For simplicity, all log messages in this section are shortened to contain only:
+    * logger name
+    * log level
+    * message
+
+Error and warning logs contain also:
+    * exception message
+    * stack trace
+
+**Do not rely on exact log messages or their presence, as they are often subject to change.**

-**Kafka service became unavailable after producer for a given topic was successfully created**
-
-
-After receiving a **Ves Common Event**, **HV-VES** creates a producer for a given topic and keeps it for the whole lifetime of an application.
-If Kafka service becomes unreachable after the producer creation, you will see the following logs when trying to establish another connection with the Kafka server.

-**server.p12** and **trust.p12** are default names of key and trust stores. They can be changed by specifying **--trust-store** or **--key-store** command line arguments on deployment.

 The above is logged when provided keystore has invalid or corrupted content.
 This log also appears when you try to use key store/trust store in archive format other than **PKCS12** (the only supported by **HV-VES** store type).
