Logging¶

The gateway captures a record of activities within a trouble log (tlog). The information is listed sequentially by time and provides a severity code for each event listed. The severity codes are listed below.

You can view the tlog from the Web Manager, as CLI output, or you can configure the serial Line to output tlog activity.

Accessing the Trouble Log¶

To view the trouble log from a web browser:

On an Internet browser, type "/tlog" after the module's IP address (http://<device IP address/tlog).

The tlog is displayed in the browser.

To configure a Line to tlog:

Configure Line 1 or a Virtual Line, and select "Trouble Log" as the protocol.

Access the line using a terminal or PC running a terminal emulator to view the tlog on the device.

To view the trouble log from the CLI:

From the CLI, type tlog from the root level.
