Chapter 4 Modifying IPM Components
Setting IPM Database Preferences
The IPM database preferences file allows you to control these parameters and also define the business
hours and days. Defined business hours are used in determining the daily, weekly, and monthly averages,
whereas business days are used in determining the weekly and monthly averages.
The database preferences file also allows you to set the length of time that daily data is retained in the
database.
Note Bad data from SA Agent can affect daily, weekly, and monthly statistical reports. To prevent this, IPM
filters very large values (greater than 999999) and negative values from the data that it receives from the
SA Agent.
Information about viewing and changing the database preferences is provided in the following sections:
• Displaying the Current Database Preferences
• Changing the Database Preferences
• Database Preferences File Format
Displaying the Current Database Preferences
To display the preferences in the currently running IPM database in Solaris, enter:
# cd /opt/CSCOipm/bin
# ./ipm dbprefs view
In Windows, enter:
cd c:\Program Files\Internetwork Performance Monitor\Server\bin
ipm dbprefs view
To display the preferences in the configuration file (which might differ from the preferences in the
currently running IPM database), in Solaris, enter:
# cd /opt/CSCOipm/bin
# ./ipm dbprefs viewfile
In Windows, enter:
cd c:\Program Files\Internetwork Performance Monitor\Server\bin
ipm dbprefs viewfile
The output from the view and viewfile versions of this command is formatted differently because
ipm dbprefs view displays the contents of a database, but ipm dbprefs viewfile displays the contents of
a file.
Changing the Database Preferences
To change the IPM database preferences:
Step 1 Edit the IPM database preferences file (/opt/CSCOipm/etc/ipmDbPref.conf in Solaris; c:\Program
Files\Internetwork Performance Monitor\server\etc\ipmDbPref.conf in Windows) using a text editor.
Step 2 Change the number of days that daily network performance statistics are stored, modify the following
line:
ipm_daily_stats_life=180
Step 3 Set the business hours to be used in calculating averages, you must turn on or off the appropriate hourly
interval.
