Local logging is not supported on UX1000 models. Instead, please use Remote logging.

The Local Logs tab displays a listing of log files stored locally on the UX file system. UX system logs can record every internal and external action the UX system performs, including user visible actions (such as placing calls), as well as internal parsing and messaging operations. The actual level of logging detail is configurable by Setting the Local Log Level.

The Local logging facility maintains two differently named log files:

  • webui.log: This file contains the current log messages being sent by the UX System. The contents of this file are directly stored in-memory to reduce the I/O overhead on the overall UX system. This log file gets automatically rotated, see Understanding Local Log Rotation Rules.

  • nvwebui_<timestamp>.log: When the webui.log file is rotated manually (or automatically) its contents are copied from memory to the local UX disk. The file is then named nvwebui_<timestamp>.log where <timestamp> represents the time when webui.log was rotated. The UX system stores a maximum of 6 local log files on disk.

Working with Local Logs

  1. In the WebUI, click the Logs tab.
  2. In the Logs page, click the Local Logs tab.


Locally stored log files can be directly viewed from the UX Web interface. To do so, simply click the expand () icon next to the log file you wish to preview the log in place, or click the popup () icon to preview in a separate window.

It is not recommended to preview log files greater than 2 Megabytes in size as this may slow down your browser. Please consider downloading the logs instead.


To download a copy of any local log file (or Web Access/Error log), simply click the Download button located under the Actions column.


Aside from automatic log rotation, you can directly rotate the current webui.log from memory to disk from the UX Web interface. To do so, simply click the Rotate button located under the Actions column.

Please note that the system can store up to 6 local log files. When you rotating the current log file, the 6th local log file on disk is deleted to make way for the newly rotated file.

Web Access and Web Error Logs

In addition to the Local log, the UX system also keeps exclusive tracking of the internal and external actions strictly having to do with the system's Web Server. The Web Server on UX is responsible for serving requests to and from the Web Interface and the UX REST API. These logs are typically used only when troubleshooting issues with UX that do not have to do with telephony traffic.

Similarly to the Local logging facility, the automatic log rotation rules applies, and user are able to Preview, Download, and Rotate those files.
