Step 2. Click on a file name in the list.
Step 3. Click on Open to open the file or Cancel to exit without changing host files.
The hosts are displayed on the Host Manager screen. The monitored hosts are also
displayed on the System Manager screen.
Using Multiple Host Files
To use multiple host files to monitor varying sets of agent hosts, the following
suggestions may be useful:
• Since the sentinal.hosts file is always loaded when the System Manager starts,
do not enable any of the hosts in it. This prevents the System Manager from polling
any of the agent hosts.
• After you start the System Manager, load the host file of your choice. It can have
hosts enabled in it.
• To switch to another host set without stopping your current agents, exit from the
System Manager and restart it. Then load the new host file.
