As needed, you can modify via parameter the logging levels for the following services of the platform. These settings should only be modified when you are debugging an issue. After the issue is resolved, you should set the logging level back to its original value.
You can apply this change through the Admin Settings Page (recommended) or trifacta-conf.json.
For more information, see Platform Configuration Methods.
Tip: You can download service logs through the application. See System Services and Logs.
For more information on these services, see System Services and Logs.
For more information on logging levels, see https://logging.apache.org/log4j/log4j-2.6.1/manual/customloglevels.html.
Masking PII
You can use the following settings to mask personal information in the log files. However, doing so may complicate debugging:
| Logging Parameter and Default Value | Description |
|---|---|
"logging.piiMask.enabled": false, | Set this value to |
"logging.piiMask.salt": "this is a grain of salt", | When PII masking is enabled, this value can be used as a randomizing element for generating hashed values. |
Configure log format
You can configure the fields and format of them for the following log files:
| Service | Applicable Log Files | Parameter |
|---|---|---|
| VFS Service | vfs-service.access.log | vfs-service.loggerOptions.format |
| WebApp | webapp.access.log | webapp.loggerOptions.format |
NOTE: This field configuration applies only the log files listed above.
For each of the above parameters, you can use a token-based method of configuring the fields to include in a log entry. You can modify:
- The sequence of fields
- The fields to include
- For some fields, you can specify specific subsets of the available information.
Entries are specified as space-delimited fields, each of which begins with a colon:
:field1 :field2 :field3
For more information on these log format options, see https://github.com/expressjs/morgan#tokens.
Configure output format
By default, logs are in flat text format and exported as .log files.
Some loggers enable output in JSON format.
NOTE: JSON format is not recommended for Designer Cloud Enterprise Edition. You may not be able to download logs in JSON format.
To enable JSON format, locate the appropriate parameter, where the wildcard below represents the service. Set the value to true:
"*.loggerOptions.json": true,
Save your changes and restart the platform or service.
