You can create a new statistic and then use it in statistic profiles and statistic charts. To use a new statistic to create a statistic event generator, you must specify a threshold.

About this task

You can create an operating system statistic for use as a template. You can create a new statistic template that includes a variable. For example, you can create a statistic that includes the variable portname. Then to collect statistics on more than one port, copy the statistic and replace the variable with the actual port name.

When you create a statistic, you define the type of data the statistic will collect and the measurement unit. You also specify whether it is an operating system statistic or a trended statistic.

Trended statistics are gathered by the Activity Trends Collector task, and used to provide activity trends statistics information.

Procedure

1. From the Domino® Administrator, click the Configuration tab, and open the Monitoring Configuration -> Names & Messages (Advanced) -> Statistic Names view.

2. Click New Statistic.

3. On the Basics tab, complete these fields:

Table 1. Basics tab

Field	Action
Statistic name	Enter the name of the new statistic.
Data type	Choose one: Text Number Time
Statistic unit	Enter one: The unit in which the statistic is measured -- for example, bytes or minutes The word none, if this is a text statistic
Statistic description	Enter a description of the statistic

• If you selected Text or Time as the data type, go on to Step 5.
• If you selected Number as the data type, in the Normal values field, enter a normal value for this statistic -- for example, 350KB -- or the word varies, if the normal value of the statistic varies.

6. For the field Is an Activity statistic? the default is No. Check Yes if the if the statistic is generated using the Activity Trends Collector task, and then check one or more of the following:

• Has trended values -- If the statistic has both trended and last-occurrence values.
• Has prime/24-hour values -- If the statistic includes values for the prime shift and for a 24-hour period.
• Is user selectable -- If the statistic will be used as a selection -- for example, in a dialog box.
• Used in resource balancing -- If the statistic will be used when balancing resources using Activity Trends.

8. For the field Useful for thresholds? the default is No. Check Yes if this statistic will be used to generate statistic alarms. To use this statistic in a statistic event generator, you must define a threshold. Complete these fields:

Table 2. Options for a threshold

Field	Action
Threshold operator	Select the condition against which to evaluate the threshold: Less than Greater than Multiple of Percentage of
Threshold value	Enter a number.
Event severity	Select the severity that will cause an alarm.
Suggested response	Enter an explanation of a how to resolve the event that caused the alarm.
Useful in setup	Click Yes to use the statistic during setup and include this statistic when a new Monitoring Configuration database (EVENTS4.NSF) is created.
