3. In the General screen, enter a name, leave Enabled checked, enter a polling interval (5
minutes is the default). For this example, check Retain polled data and accept the
remaining defaults for checkboxes and the retention policy.
4. Select an ent
ity to monitor by clicking the Add button in the top portion of the Monitor
Options screen. For an interface monitor, select Interface as the Type at the top of the
screen. You can also filter the list of interfaces that appear further by selecting Interface
Type as Ethernet, for example.
Tip: Notice that you
can add refinements like filtering on Administrative State
and IP Address to the filter.
5. Select inte
rfaces (Ctrl+click to add more than one), then click Add Selection then Done to
confirm your entity.
Tip: Hove
r your cursor over a line describing an interface to have a more
complete description appear as a popup.
6. Click Browse to
display the MIB Browser (see SNMP Monitor on page 110) For the sake of
this example, we elect to monitor ifInErrors (in RFC Standard MIBs, RFC1213-MIB > Nodes
> mib
-2 > interfaces > ifTable > ifEntry > ifInErrors).
7. In the Thre
sholds screen, configure thresholds by first clicking Add.
8. In the threshold editor
, enter a name (Examples: Low, Medium, Overload), an upper and
lower boundary, (0 - 10, 10 - 100, 100+), a severity (Informational, Warning, Critical) and
color (BLUE, YELLOW, RED). In this case, no string matching is necessary. When the data
crosses thresholds, the monitor reacts.
Attributes available depend on the type of monit
or you are creating. Notice that, you can
also check to make crossing this threshold emit a notification (an alarm that would appear
on the Alarm panel). You can also configure the type of calculation, and so on. You can
even alter existing thresholds, by selecting one, then clicking Edit to the right of the
selected threshold.
Note: If a threshold’s counter is an SNMP Counter32 (a 32-bit counter)
monitoring can exceed its capacity with a fully utilized gigabit
interface in a relatively short period of time. The defaults configured
in this monitor account for this, but if you know that this is an issue,
you can probably configure the monitor to account for it too.
After taking a look at Thresholds no more configuration is required. Notice, however, that
you can also configure Calculated Metrics and Inventory Mappings on other screens in
this editor to calculate additional values based on the monitored attributes, and to map
them.
