Logging

The log messages produced by Qlik Sense provide important information that can be used to detect security incidents, operational problems, and policy violations.

The logging is based on the log4net component in Apache Logging Services. This means that Qlik Sense uses a standardized logging framework and conforms to standard logging procedures.

New logging framework

A new logging framework was introduced in Qlik Sense version 2.0. Unless otherwise stated, the documentation describes the new logging framework.

Legacy logging framework

The legacy logging framework is still available in Qlik Sense, but the logs are as of Qlik Sense version 2.0 referred to as trace logs. The log files remain the same, but they are stored in a new location.

See: Trace logs

Reading and analyzing log files in Qlik Sense

The log files can be read and analyzed using Qlik Sense, which includes the following pre-defined, log-related data connections after installation:

• ServerLogFolder: Links to the active log files.
• ArchivedLogsFolder: Links to the archived log files.

The data connections can be edited in the Qlik Management Console (QMC).

In addition, users with root, security, content, or deployment administrator rights can use the Qlik Sense log data in apps by selecting one of the data connections listed above in the data load editor.
