In the Maximum days to maintain event history field, enter the number of days 
you want to retain event data in the database log. At midnight of each day, old 
records are purged if their start time is older than the maximum allowed days.

In the Data Collection box, do you want the system to record data collection 
failures in the event log?
• If 
yes
, put a check mark in the box next to the Log Event on failure field. 
Set the alert level for the event by clicking on the arrow in the Alert level 
pull-down list and selecting one of the options.
• If 
no
, leave the box unchecked. The system will not record any data 
collection errors in the event log, even if data collection parameters have 
been established.
4In the Scheduled Reports box, do you want the system to record report 
generation failures in the event log?
• If 
yes
, put a check mark in the box next to “Log Event on failure”. Set the 
alert level for the event by selecting one of the options listed in the Alert 
level pull-down list.
• If 
no
, leave the box unchecked. The system will not record any report 
generation failures in the event log.
5In the Call Processing Occupancy box, do you want the system to record call 
processing occupancy exceptions in the event log?
• If 
yes
, put a check mark in the box next to “Log event when exception 
occurs” in the Call Processing Occupancy box. Set the alert level for the 
event by clicking on the arrow in the Alert level pull-down list and 
selecting one of the options.

• If 
no
, leave the box unchecked. The system will not record any call 
processing occupancy exceptions in the event log.
The G3r occupancy threshold field reflects the maximum percent of CPU 
occupancy being used by the call processing software for DEFINITY G3r 
switches before an event is generated. Enter the threshold percent in this 
field by typing the percent or by clicking the up or down arrows to obtain 
the desired percent.
The Non-Gr3 occupancy threshold field sets the default call processing 
occupancy threshold for switches other than the DEFINITY Gr3. Fill in this 
field as described in the G3r field.
6In the Trunk Groups box, do you want the system to record trunk group grade 
of service exceptions in the event log?
• If 
yes
, put a check mark in the box next to “Log event when exception 
occurs”. Set the alert level for the event by clicking on the arrow in the 
Alert level pull-down list and selecting one of the options.
• If 
no
, leave the box unchecked. The system will not record any trunk 
group grade of service exceptions in the event log.
In the Model field, select the model to use in calculating trunk group grade 
of service. Choose the model whose assumptions most closely match 
your situation.
The Erlang B model assumes that calls that are blocked from accessing 
the trunk group are cleared from the system.

The Erlang C model assumes that there is an infinite queue for calls trying 
to access the trunk group to wait in until resources are available.  This 
means that all calls are eventually served.
The Retrial model assumes that some calls are blocked but will retry.  The 
Retrial model is an approximation using the average of the results of the 
Erlang B and Erlang C models.
Choose one of the following options:
• Erlang B
• Erlang C
• Retrial
In the Service objective field, type a number between .001 and .700 that 
represents the percent of calls that may be blocked from accessing that 
trunk group based on the current call activity. Trunk group grade of 
service events are generated when the computed service objective 
exceeds the value in this field.

Set Processor Occupancy Alerting ParametersIntroduction
This procedure describes how to override the default processor occupancy 
alerting parameters for a specific managed node.
Procedure
To set processor occupancy alerting parameters, do the following:1From the left window pane, click 
DEFINITY Systems > [managed node] > 
Processor Occupancy > Alerting Parameters
Result: 
Displays the Processor Occupancy Alerting Parameters pane for the 
managed node you selected.

Do you want the system to record call processing occupancy exceptions in 
the event log?
• If 
yes
, put a check mark in the box next to “Log event when exception 
occurs”. 
• If

pull-down list and selecting one of the options.5In the Call processing threshold field, enter the maximum percent of CPU 
occupancy being used by the call processing software before an event is 
generated. Type the percent or click the up or down arrows to obtain the

parameters for a specific managed node.
Procedure
To set the trunk group alerting parameters, do the following:1From the left window pane, click 
DEFINITY Systems > [managed node] > Trunk 
Groups > Alerting Parameters.
Result: 
Displays the Grade of Service Alerting Parameters pane for that 
managed node. The columns on the left side of the table identify the 
trunk group number, name and number of trunks. These columns 
cannot be changed. The remaining fields can be changed if the 
Default? box is not checked.

Click in the Default column for the trunk group you want to change so that the 
Default? box is unchecked.Result: 
You can now change the parameters in the remaining columns.
Note: 
If the Default box is checked, the system will use the global default values 
to determine when to record alerts. The remaining fields will display the 
default values and cannot be changed.

In the Log column, put a checkmark in the box if you want the system to 
record trunk group grade of service exceptions. If you do not want to record 
exceptions, leave the box unchecked.4In the Level column, set the alert level for the event by clicking on the arrow in 
the Alert level pull-down list and selecting one of the options.5In the Model column, select the model to use in calculating trunk group grade 
of service. The Retrial calculation is an approximation of the standard Retrial 
calculation. It is basically the average of Erlang B and Erlang C.
Choose one of the following options:
• Erlang B
• Erlang C
• Retrial6In the Service Objective column, type a number between .001 and .700 that 
represents the percent of calls that will be blocked from accessing that trunk
