118 Configuring Dell OpenManage IT Assistant to Monitor Your Systems
Selecting An Appropriate Discovery Time-Out Value for the Network
Since Tom is monitoring remote systems across a WAN, time-out values may
differ significantly between local systems and those further removed. In this
case, it is recommended that Tom determine and set an appropriate time-out
for the discovery of the systems located over the WAN.
In environments with long network latency times, such as global WANs, Tom may
want to consider increasing ping time-outs across the enterprise. He can determine
the ping times of systems that exhibit the greatest latency on the network by using
the Too lsTroubleshooting Too l and selecting the Device Connectivity tab.
From there, Tom can test the connection of high-latency systems to see whether
he should increase specific ping times for better WAN performance.
Configuring Discovery Settings for the First Time in the Enterprise Network
Like Jane, if this is the first time IT Assistant has been launched since
installation, Tom is presented with a welcome screen indicating that
IT Assistant has not yet been configured. The four basic steps of
configuration are listed:
Step 1: Discovery Configuration
Step 2: Inventory Configuration
Step 3: Status Polling
Step 4: Ranges
Clicking any of the steps will take him to the corresponding dialog box under
the Discovery and Monitoring menu bar in IT Assistant. Steps 1 through 3
are single-window dialog boxes; step 4 is a wizard-based procedure for
defining discovery ranges.
Configuring Discovery Configuration Settings
Tom begins by configuring the discovery settings for his systems using
the Discovery Configuration Settings dialog box. This dialog is displayed
either automatically when he clicks Step 1: Discovery Configuration from the
IT Assistant welcome screen or by choosing Discovery Configuration from
the menu bar. Here, Tom enters information that IT Assistant will use for
discovery. These values remain unchanged and apply to all the discovery
ranges he will create later in this procedure. However, he can change these
values at any time using this dialog box.
