57.5 Filtering Syslog Messages and Debug Recordings
The device can filter Syslog messages and debug recording (DR) packets, which are sent
to a Syslog server and packet capturing application (such as Wireshark), respectively.
Filtering can be useful to reduce CPU consumption and minimize negative impact on VoIP
performance.
You can configure up to 30 filtering rules, each based on a selected filtering criteria (e.g.,
an IP Group). Each filtering criteria can be configured with a range. For example, you can
filter Syslog messages for IP Groups 1 through 4. For each filter criteria, you can enable or
disable Syslog messages and debug recording.
Debug recording can also be filtered using various filtering criteria such as SIP signaling or
signaling and media.
The following procedure describes how to configure Logging Filter rules in the Web
interface. You can also configure Logging Filter rules using the table ini file parameter,
LoggingFilters or the CLI command configure system > logging > logging-filters.
To configure a logging filtering rule:
1. Open the Logging Filters Table page (Configuration tab > System menu > Logging
> Logging Filters Table).
2. Click Add; the following dialog box appears:

4. Click Submit, and then save ("burn") your settings to flash memory.
Note: To configure the Syslog debug level, use the 'Debug Level' parameter (see
''Enabling Syslog'' on page 737).
