OneSight Administrator Guide

Configuring DNS Monitors
Sample Every: – Specifies how often samples are
taken for this monitor. Refer to, ―Sample Every Settings,‖ later
in this chapter for a description of these settings.
Test – When you add or modify a monitor, you can test settings
to determine if they are set appropriately. After clicking the
Test button, you will see messages in the status window as the
test runs and when the test completes.
3. Each monitor that you add must have a unique name. You can
let OneSight create a unique name using the DNS specifications
you supply, or you can type in your own name for the monitor.
4. On the General tab in the DNS Server box, type in the IP
address of the domain name server that you want to monitor.
5. Type in a Host Name that the DNS server should resolve. You
can also type in the IP address of the host name you specify in
the Host Address box so that the monitor will verify that the IP
address returned by the DNS server matches the address you
specify here.
6. By default, a DNS monitor will check the availability and
responsiveness of the domain name server every 10 minutes and
will time out after 10 seconds if the name is not resolved. If you
want the monitor to sample more or less frequently, change the
sampling interval. If you want to have the timeout occur earlier
or later, change the Timeout setting.
7. To verify that the monitor will work as configured, click the
Test button. The Monitor Test window provides information
about the success or failure of the test and indicates what may
be causing any problem.
8. If the test succeeds, click OK in the Add Monitor dialog box to
save these basic DNS monitor settings. You can now add this
monitor to a monitor group. Refer to Adding Monitors to a
Monitor Group in Chapter 4.
