Overview
In order to standarize the errors and logs handled by each component, some conventions have been taken, as log patterns, error codes definition or messages content.
The information on this page should be used by each partner who develop a DE4A component, also it should be maintained to have a proper messages reference and be aware which information will include.
Apart from the usual reasons of the logging and error handling, in the DE4A project, there are 3 main bullet points on which the messages definition are supported:
- Kafka tracking: messages sent to the Kafka server which can be previewed at: https://de4a-dev-pt.egovlab.eu/#!detail
- Metrics logs: messages marked with a special tag inside the common log file or logged on a separated file, which will be used to analyze and raise some metrics about each system
- Error convenction: standarize the error messages and codes
Structure definition
This section will describe the hierarchy and model followed to build the different logs and messages. There are multples pattern depending on the message nature, but the following tables will be a common reference to understand the rest of information collected in the page.
Layer
The layer concept will be used to name the system level where the message comes from.
| Layer | Layer Code | Description |
|---|---|---|
| Communication | 1 | External connections/communications performed by the Connector |
| Internal failure | 2 | Internal failure of the Connector to be handled and stored in ErrorTypes wrapped in DE4A responses |
| Configuration | 3 | Unexpected situation due to a missing configuration paramater |
| Business | 4 | Unsuccessful situation on the business flow |
Module
A reference to each DE4A module possibly involved in an interaction. A "None" element has been included to represent the situation where a message occurs internally in a certain component
| Module Name | Module Code |
|---|---|
| IDK | 01 |
| SMP | 02 |
| Connector DR | 03 |
| Connector DT | 04 |
| Data Owner | 05 |
| Data Evaluator | 06 |
| None | 07 |
Type
It is mean to use just for the Connector log messages (metrics and Kafka)
| Log Type | Type code |
|---|---|
| Services | 01 |
| Client | 02 |
| AS4 | 03 |
Error messages
As part of the logging standardization, some error messages templates have been defined. Those messages will be thrown by each component with the corresponding parameterization.
| Error message | Code | Parameters |
|---|---|---|
| Service requested {0} not found | 01 | {0}: REST service requested |
| Arguments missing or invalid at {0} - {1} | 02 | {0}: Service requested
{1}: Missing arguments |
| Connection error with {0} - {1} | 03 | {0}: Module name
{1}: Inherited error message |
| Error on response from {0} - {1} | 04 | {0}: Module name
{1}: Inherited error message |
| Object conversion error on {0} - {1} | 05 | {0}: Module name
{1}: Inherited error message |
| Error accessing/saving data on {0} - {1} | 06 | {0}: Module name
{1}: Inherited error message |
| Scheme validation failed for {0} message - {1} | 07 | {0}: Message type
{1}: Inherited error message |
| Error occurred on AS4 Gateway to {0} - {1} | 08 | {0}: Module name
{1}: Inherited error message |
| Failed to establish user identity | 09 | - |
| Error extracting evidence | 10 | - |
| Error in identity matching | 11 | - |
| Unsuccessful completion of preview | 12 | - |
| Preview rejected by user | 13 | - |
| Failed to re-establish user identity | 14 | - |
| Evidence not available yet (delayed) | 15 | - |
| Unsuccessful generation of the canonical evidence | 16 | - |
