Analyze the Log

Log files are generated by Talend Data Catalog for most process such as model import.

Information note

The bridges do not use log4j and does not log into the tomcat log file but in its own set of files. Thus, one cannot go to the data/logs/tomcat folder for import (or export) logs.

Steps

To review a process log

  1. Go to the MANAGE
  2. > Configuration.
  3. Select the model for which the process occurred (e.g., the model for a model import process)
  4. Click on the Log tab.
  5. Select the specific process log you wish to review.
Information note

There may be several logs for the same type of process, e.g., repeated imports of a model, so knowing the date and time is crucial. Generally, though, one will want the latest log at the end of the list.

Information note

You may delete a log at this time. All deleted logs are removed from the database and cannot be retrieved.

Information note

You may also schedule a regular maintenance task called Purge failed logs to clean up older logs of processes that failed.

Log level messages

Log messages come in five levels:

Level

Description

Debug

Special diagnostic messages

Information

Basic informational message (e.g., parameter settings, connection events, etc.)

Status

Process step status messages (e.g., Importing model…)

Warning

Lower level issues identified which may compromise the results of the process

Error

Higher level issues identified which do compromise the results of the process and potentially cause it to fail entirely

Click on the level next to Show at the bottom of the Log Message dialog to pick the log level being displayed.

Example

After importing a model, you go to MANAGE > Configuration and select the model. Then click on the Log tab and select the latest timestamped log and click View Log.

Here we have selected All in the Show level pick list ensuring that all levels of log message are displayed.

Information note

To search a log, click Save Log to download the log to a text editor.
