In-Depth Information
Clicking Create Blackout opens the Create Blackout wizard, shown in Figure
4-57
. As you can see, the blackout
functionality is quite extensive and can apply to composite targets (most commonly a host and all targets running on
that host).

Don't use blackouts to hide alerts that you don't want or know how to investigate. this
always
leads to missing
alerts that you should have picked up. Instead, use blackouts only for planned maintenance.
Tip
Log Review
The target type menu also provides a handy Logs submenu for reviewing the system logs associated with various
targets (see Figure
4-58
). The menu itself is common to all targets, but the available level of detail depends on the
nature of the target and the plug-in designer. In the case of a database, for example, the Logs submenu gives you
access to review the
alert.log
file, to review all recorded errors, and to manage trace files.
