Resource Monitors | Monitoring
How To:
Create an SNMP Interface Monitor
To set up a typical performance monitor, follow these steps:
1
In the Resource Monitors portlet, and create a new monitor by right-clicking and selecting
New .
2
Select the type of monitor from the submenu—for this example, an SNMP Interfaces
monitor.
NOTE:
Some devices have ports rather than interfaces. This monitor works for them too, even though it is an
“interface” monitor.
3
In the General screen, 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 entity 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 ge
(gigabit ethernet), for example.
Tip
Notice that you can add refinements like filtering on
Administrative State
and
IP Address
to the filter.
5
Select interfaces (Ctrl+click to add more than one), then click Add Selection then Done to
confirm your entity.
Tip
Hover 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. 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 Thresholds screen, configure thresholds by first clicking Add.
8
Click Add above the threshold levels list for each threshold you want to add.
9
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.
