Syslog Message Description For Cpu Overload - AudioCodes E-SBC User Manual

CHAPTER 58 Syslog and Debug Recording
●
●
■ Device's CLI: The device sends error messages (e.g., Syslog messages) to the CLI as well
as to the configured destination.
● To start debug recording:
debug log
● To stop debug recording:
no debug log
● To stop all debug recording:
no debug log all
■ Wireshark: Third-party, network protocol analyzer (http://www.wireshark.org).
When debug recording is enabled and Syslog messages are also included in the debug
recording, to view Syslog messages using Wireshark, you must install AudioCodes'
Wireshark plug-in (acsyslog.dll). Once the plug-in is installed, the Syslog messages are
decoded as "AC SYSLOG" and displayed using the "acsyslog" filter (instead of the
regular "syslog" filter). For more information on debug recording, see
■ Third-party, Syslog Server: Any third-party, Syslog server program that enables filtering of
messages according to parameters such as priority, IP sender address, time, and date.

Syslog Message Description for CPU Overload

Whenever the devicedetects a CPU overload, it sends a Syslog message that shows CPU
utilization of the different processes (tasks) per core. This information can help in identifying the
cause of the overload. When the devicedetects a CPU overload, it sends a Syslog message every
10 seconds until it returns to normal state.
You can also view CPU utilization through the CLI, by using the following command:
show system utilization
The figure below shows an example of a Syslog message generated because of a CPU overload.
CPU utilization information is shown under the "CPUUtilMonitor" section (shown in pink). The
subsequent table describes the displayed information.
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.
