Parameter Description
Enables the protection of 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 (threshold), the device automatically lowers the
debug level to free up CPU resources that were required
for the previous debug-level functionality. When sufficient
CPU resources become available again, the device
increases the debug level. The threshold is configured by
the 'Debug Level High Threshold' parameter (see below).
■ [0] Disable
■ [1] Enable (default)
Defines the threshold (in percentage) for automatically
switching to a different debug level, depending on CPU
usage. The parameter is applicable only if the 'Syslog CPU
Protection' parameter is enabled.
The valid value is 0 to 100. The default is 90.
The debug level is changed upon the following scenarios:
■ CPU usage equals threshold: Debug level is reduced
one level.
■ CPU usage is at least 5% greater than threshold:
Debug level is reduced another level.
■ CPU usage is 5 to 19% less than threshold: Debug
level is increased by one level.
■ CPU usage is at least 20% less than threshold: Debug
level is increased by another level.
For example, assume that the threshold is set to 70% and
the Debug Level to Detailed (5). When CPU usage
reaches 70%, the debug level is reduced to Basic (1).
When CPU usage increases by 5% or more than the
threshold (i.e., greater than 75%), the debug level is
disabled - No Debug (0). When the CPU usage decreases
to 5% less than the threshold (e.g., 65%), the debug level
is increased to Basic (1). When the CPU usage decreases
to 20% less than the threshold (e.g., 50%), the debug level
changes to Detailed (5).
Note: The device does not increase the debug level to a
level that is higher than what you configured for the 'Debug
Level' parameter.
Defines the time zone that is displayed with the timestamp
in CDRs. The timestamp appears in the CDR fields "Setup
Time", "Connect Time", and "Release Time".
The valid value is a string of up to six characters. The
default is UTC. For example, if you configure the
parameter TimeZoneFormat = GMT+11, the timestamp in
CDRs are generated with the following time zone display:
17:47:45.411 GMT+11 Sun Jan 03 2018
Note: The time zone is only for display purposes; it does
not configure the actual time zone.
