User's Manual 55. Syslog and Debug Recording
To configure the Syslog debug level:
1. Open the Syslog Settings page (Troubleshoot menu > Troubleshoot tab > Logging
folder > Syslog Settings).
Figure 55-4: Configuring Syslog Debug Level
2. From the 'Debug Level' (GwDebugLevel) drop-down list, select the debug level of
Syslog messages:
• No Debug: Disables Syslog and no Syslog messages are sent.
• Basic: Sends debug logs of incoming and outgoing SIP messages.
• Detailed: Sends debug logs of incoming and outgoing SIP message as well as
many other logged processes.
3. From the 'Syslog Optimization' (SyslogOptimization) drop-down list, select whether
you want the device to accumulate and bundle multiple debug messages into a single
UDP packet before sending it to a Syslog server. The benefit of the feature is that it
reduces the number of UDP Syslog packets, thereby improving (optimizing) CPU
utilization. The size of the bundled message is configured by the
MaxBundleSyslogLength parameter.
4. From the 'Syslog CPU Protection' (SyslogCpuProtection) drop-down list, select
whether you want to enable the protection feature for the device's CPU resources
during debug reporting, ensuring voice traffic is unaffected. If CPU resources drop
(i.e., high CPU usage) to a critical level (user-defined threshold), the device
automatically lowers the debug level to free up CPU resources that were required for
the previous debug-level functionality. When CPU resources become available again,
the device increases the debug level to its' previous setting. For example, if you set
the 'Debug Level' to Detailed and CPU resources decrease to the defined threshold,
the device automatically changes the level to Basic, and if that is not enough, it
changes the level to No Debug. Once CPU resources are returned to normal, the
device automatically changes the debug level back to its' original setting (i.e.,
Detailed). The threshold is configured by the DebugLevelHighThreshold parameter.
5. Click Apply.
55.2.5 Configuring Reporting of Management User Activities
The device can report operations (activities) performed in the device's management
interfaces (e.g., Web and CLI) by management users, in Syslog messages. The Syslog
message indicates these logs with the string "Activity Log". Each logged user activity
includes the following information:
Username (e.g., "Admin") of the user that performed the action
IP address of the client PC from where the Web user accessed the management
interface
Protocol used for the session (e.g., SSH or HTTP)
The following example shows a Web-user activity log (indicating a login action) with the
above-mentioned information:
14:07:46.300 : 10.15.7.95 : Local 0 :NOTICE : [S=3149]
[BID=3aad56:32] Activity Log: WEB: Successful login at
10.15.7.95:80. User: Admin. Session: HTTP (10.13.22.54)
