## Event log

To view the event log of the NanoTrack server, go to the Administration Panel and click Event Log.

Figure 5.3. The event log

The event log contains information about errors, access to the system, important administrative operations and cron job executions. It is independent from the logs of PHP, the web server and the operating system. Its purpose is to supplement those information, not to replace them. In particular, some serious errors (such as lack of access to the database) cannot be stored in the event log of the NanoTrack server.

Events in the event log are divided into four types:

Errors

  Errors and warnings in the system NanoTrack. They may result from incorrect input data, lack of permission to perform some operations, conflicts between parallel changes or incorrect system configuration.

Access

  Information about successful and failed attempts to log into the system, as well as errors associated with the denial of access to specific pages or operations.

Audit

  Information about important administrative operations, such as: creating and changing passwords or permissions of users, creating, deleting and modifying issue types, attributes, projects and folders, and deleting issues.

Cron

  Information about executions of the cron job. For more information, see the section called “Cron jobs”.

Events also have three different levels of severity: information, warning and error. They are marked with different icons.

By default, the log displays all events, sorted from newest to oldest. If you are interested only in a specific type of events, click on one of the options in the upper right corner of the window to enable filtering.

Click on an event to view detailed information about it. In addition to the type, severity and full message, also the name of the user who performed the operation and the host name or IP address, from which the connection was made, are displayed.

### Note

Although detailed information about errors are stored in the event log, for security reasons they are not displayed on error pages. However, you can enable detailed error messages for development or troubleshooting purposes. You can also enable an additional text log which makes debugging easier. However, you should not enable those settings in production environment. For more information, please visit http://wiki.mimec.org/wiki/NanoTrack/Configuration.

Events are automatically removed from the log after a specified amount of time. For more information about configuring this period, refer to the section called “Advanced settings”.
