Troubleshooting
===============
**NOTE**
According to **ONAP** logging policy, **Mapper** logs contain all required markers as well as service and client specific Mapped Diagnostic Context (later referred as MDC)
Default console log pattern:
::
|%date{"HH:mm:ss.SSSXXX", UTC}\t[ %thread\t] %highlight(%-5level)\t - %msg\t
A sample, fully qualified message implementing this pattern:
::
|11:10:13.230 [rcc-notification] INFO metricsLogger - fetch and publish from and to Dmaap started:rcc-notification
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.**
Deployment/Installation errors
--------------------
**Missing Default Config File in case of using local config instead of Consul**
::
|13:04:37.535 [main] ERROR errorLogger - Default Config file kv.json is missing
|13:04:37.537 [main] ERROR errorLogger - Application stoped due to missing default Config file
|13:04:37.538 [main] INFO o.s.s.c.ThreadPoolTaskExecutor - Shutting down ExecutorService 'applicationTaskExecutor'
|15:40:43.982 [main] WARN debugLogger - All Smooks objects closed
**These log messages are printed when the default configuration file "kv.json", was not present.**
**Invalid Default Config File in case of using local config instead of Consul**
If Default Config File is an invalid json file, we will get below exception
::
|15:19:52.489 [main] ERROR o.s.boot.SpringApplication - Application run failed

|15:19:52.493 [main] WARN debugLogger - All Smooks objects closed
**Invalid Smooks mapping file**
If VES-Mapper blueprint or local config file contains invalid Smooks mapping file, then we will get below SAXException / JsonProcessingException / JsonSyntaxException / JsonParseException while processing the incoming notifications and the notification will be dropped without converting into required VES event. All such dropped notifications will be logged in error log file.
