Managing Local Logs

Getting Started with Local Logs

The Diagnostics tab displays a listing of log files stored locally on the

SBC 2000 and SBC SWe Lite file systems. System logs can record every internal and external action the systems perform, 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.

Preview

Locally stored log files can be directly viewed from the

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.

Download

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

Rotate

Aside from automatic log rotation, you can directly rotate the current webui.log from memory to disk from the

SBC 2000 and SBC SWe Lite Web interface. To do so, click the Rotate button located under the Actions column.

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

Working with Local Logs

The Local logging facility maintains two differently named log files:

• webui.log: This file contains the current log messages being sent by the
  Unable to show "metadata-from": No such page "_space_variables"
  SBC 2000 and SBC SWE Lite Systems. The contents of this file are directly stored in-memory to reduce the I/O overhead on the overall
  Unable to show "metadata-from": No such page "_space_variables"
   SBC 2000 and SBC SWe Lite systems. This log file gets automatically rotated, refer to 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
  Unable to show "metadata-from": No such page "_space_variables"
  SBC disk. The file is then named nvwebui_<timestamp>.log where <timestamp> represents the time when webui.log was rotated. The
  Unable to show "metadata-from": No such page "_space_variables"
  The system stores a maximum of 6 local log files on disk.

Access Local Logs as follows:

1. In the WebUI, click the Diagnostics tab.

Working with Web Access and Web Error Logs

The

SBC Edge system keeps exclusive tracking of the internal and external actions strictly having to do with the system's Web Server. The Web Server on the SBC Edge is responsible for serving requests to and from the Web Interface and the REST API. These logs are typically used only when troubleshooting issues with the SBC Edge 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.

To access Local Logs:

1. In the WebUI, click the Diagnostics tab.

2. In the Logs page, click the Logs > Web Access Logs OR Web Error Logs.
