Chapter 3 Storage Arrays 3-87
The event monitor is a separate program bundled with the client software and must
be installed with the storage management software. The client/event monitor is
installed on a storage management station or host connected to the storage arrays.
For continuous monitoring, install the event monitor on a computer that runs 24
hours a day. Even if you choose not to install the event monitor, alert notifications
must still be configured on the computer where the client software is installed,
because alerts will be sent as long as the Enterprise Management Window is
running.
Figure 3-36 shows how the event monitor and the Enterprise Management Window
client software send alerts to a remote system. The storage management station
contains a file with the name of the storage array being monitored and the address
where alerts will be sent. The alerts and errors that occur on the storage array are
continuously being monitored by the client software and the event monitor. The
event monitor takes over for the client after the client software package is shut
down. When an event is detected, a notification is sent to the remote system.
FIGURE 3-36 Event Monitor Configuration
Because the event monitor and the Enterprise Management Window share the
information to send alert messages, the Enterprise Management Window contains
some visual cues to assist in the event monitor installation and synchronization. The
parts of the Enterprise Management Window that are related to event monitoring are
shown in Figure 3-37 on page 3-88.
Using the event monitor involves three key steps:
1. Install the client software. The event monitor is packaged with the client software
and installs automatically with the client software. It is recommended that you
run the event monitor on one machine that will run continuously. To prevent
receipt of duplicate alert notifications of the same critical event on a storage array,
disable the event monitor on all but one storage management station.
