OneSight Administrator Guide

Modifying System Definitions
Instance – Enter the component that you want to monitor.
Database Instance System Information
Enter the following information for discovering named instances of
SQL databases.
Component Tab – The Component tab shows the name of the
database you are configuring. Changing this name will affect the
database entry on the left side of the System Editor dialog box.
Perfmon Tab – The Windows NT Performance Monitor (Perfmon)
can be used with OneSight to discovery multiple named instances
of SQL databases. To enable OneSight to use this information, you
must first start and configure Performance Monitor for your system.
For more information, see Perfmon.
Instance – Enter the instance names separated by a semi-colon.
For example, ABC;DEF.
Database Log File System Information
Currently, the Database log file component type is not used by any
existing profile metric. This component type will be used for
database log files when implemented in future database profiles.
Disk System Information
When you add a new disk component, you must add information to
the Properties tabs to configure the data sources that OneSight
metrics use to obtain information about the disk.
Note: If you are using Windows 2003/2008 with a firewall, you
must open the SNMP agent port configured on the SNMP tab (the
default is port 161), otherwise discovery may fail.
