Tuning and Troubleshooting OVO
Tuning Performance
❏ NNM Daemons
Do not use the logging and tracing options provided for the HP
OpenView NNM daemons (trapd, netmon, and so on) unless
absolutely necessary.
❏ Management Server
Configure the management server as a secondary Domain Name
Server (DNS).
❏ Background Graphics
Reduce the number of background graphics in the HP OpenView
submaps to a minimum.
❏ Alarm Severity Symbol
Suppress the appearance of the OVO Alarm Severity symbol in the
HP OpenView submaps by changing the OVO app-defaults file.
Set the line Opc.statusPropOnAllNodes to False in the following
file:
/opt/OV/lib/X11/app-defaults//Opc
The default setting is True.
