Viewing Syslog Messages

You can view syslog messages generated by the device using any of the following syslog server types:

■

Device's Web Interface: The device provides an embedded syslog server, which is accessed through the Web interface (Troubleshoot tab > Troubleshoot menu > Message Log

). You can select the syslog messages displayed on the page, and then copy-and-paste them into a text editor such as Notepad. This text file (txt) can then be sent to AudioCodes support team for diagnosis and troubleshooting.

The displayed logged messages are color-coded based on message type:

●

"notice": Dark green

●

"error", "crit", "alert", "emerg": Red

●

"debug": Black

●

"info": Blue

●

"warn": Magenta

The page provides various buttons to do the following actions:

Buttons on Message Log Page

Button	Description
Start	Resumes the message log after it has been stopped (see the Stop button).
Stop	Stops the message log, allowing you to easily scroll through the messages to a specific message.
Clear	Clears the message log. The button can only be clicked after you have stopped the message log (see the Stop button). Note: If you navigate away from the Message Log page to another page, the Message Log is stopped and cleared.

Button

Description

Start

Resumes the message log after it has been stopped (see the Stop button).

Stop

Stops the message log, allowing you to easily scroll through the messages to a specific message.

Clear

Clears the message log. The button can only be clicked after you have stopped the message log (see the Stop button).

Note: If you navigate away from the Message Log page to another page, the Message Log is stopped and cleared.

●

It's not recommended to keep a Message Log session open for a prolonged period. This may cause the device to overload. For prolonged (and detailed) debugging, use an external syslog server.

●

The Message Log page provides limited syslog server functionality.

■

Device's Serial Console: You can enable the device to also send the syslog messages to the serial console (over the device's physical serial interface). This may be useful, for example, if you no longer have network access to the device and you would like to perform diagnostics. To enable this feature, configure the [EnableConsoleLog] parameter to 1, and then restart the device.

■

Device's CLI: The device sends error messages (e.g., syslog messages) to the CLI as well as to the configured destination.

●

To stop debug recording:

Wireshark: Third-party, network protocol analyzer (http://www.wireshark.org).

■

AudioCodes Syslog Viewer: This utility can be used for two major tasks:

●

Recording and displaying syslog messages from the device

●

Analyzing recorded logs (including support for interactive SIP ladder diagrams)

To obtain the Syslog Viewer installation file, download it from https://www.audiocodes.com/library/firmware.
