LOGFILEROTATESIZE Triggers a log file rotation based on the size of the active file. The
application regularly checks the current size of the file to determine
whether a rotation is required. If a file rotation is triggered by this
parameter, the rotated file might be slightly larger than the size
specified by this parameter. A file rotation is triggered by this
parameter causes the timer associated with the
LOGFILEROTATEINTERVAL parameter to be reset as well.
10 Mb
LOGFILEROTATEINTERVAL Triggers a log file rotation based on the time elapsed since the
previous rotation. This timer is reset after any rotation occurs,
regardless of the cause or trigger of the rotation.

IPADDRNMS Defines the IP address of the network management system. —
OVLDSAMPLERATE Defines the frequency of CPU sampling and threshold checking. 3000 millisecond
(ms) polling rate
OVLDLEVEL1PERCENT Indicates what percentage of calls should be rejected when an
overload condition occurs. This parameter is used in conjunction with
the OVLDLEVEL1FILTER parameter. The overload level 1 value is
the lowest level of overload and must be less than or equal to the
provisioned values for OVLDLEVEL2PERCENT and
OVLDLEVEL3PERCENT.
Note If this value is set to zero, no overload level 1 treatment
occurs.
20
OVLDLEVEL1FILTER Indicates what call types should be gapped if an overload level 1
condition occurs. The possible values are:
• Normal—Emergency or priority calls are not gapped.
• All—All calls are gapped, regardless of type.
Note If the overload percentage is set to 100, all calls are gapped
irrespective of this setting.
Normal
OVLDLEVEL1THRESHLOWER
CALLS
Determines the number of active calls below which the application
load must fall in order for the overload level 1 condition to be
removed.
1800
OVLDLEVEL1THRESHUPPER
CALLS
Determines how many simultaneous active calls trigger an overload
level 1 condition.
1900
OVLDLEVEL1THRESHLOWER
CPU
Determines the CPU utilization level below which the application
must fall in order for the overload level 1 condition to be removed.
60
OVLDLEVEL1THRESHUPPER
CPU
Determines the level of CPU utilization that triggers an overload
level 1 condition.
65
OVLDLEVEL2PERCENT Indicates what percentage of calls should be rejected when an
overload condition occurs. The parameter is used in conjunction with
the OVLDLEVEL2FILTER parameter. This is the second level of
overload and must be less than or equal to the provisioned value of
OVLDLEVEL3PERCENT and greater than or equal to the
provisioned value of OVLDLEVEL1PERCENT.
Note If this value is set to zero, no overload level 1 or 2 treatment
occurs (by definition, the level 1 value must also be zero).
